See the Subversion log for all the details.

===============================================================================
Dabo 0.8 (2007-05-09) (Revision 3111):

Enhancements:

    ===== General Stuff =====
+ Improved a lot of the handling of paths. It is now possible to correctly 
  resolve a relative path when the source file and the contained file are in 
  different directories, while the app is running from a third directory.

+ Added datanav2; deprecated datanav. datanav2 no longer supports fieldSpecs,
  relationSpecs, and other things. The general theme is that the generated
  code is meant to be taken as boilerplate to be edited by the developer to
  achieve the desired results.

+ Began work on new unit testing harness, with Nate Lowrie at the helm.

+ Added/enhanced unit tests for dCursor, dBizobj, dTextBox, and dForm.

+ Big fixes and enhancements, as always, to runtime cdxml instantiation, 
  including much better inheritance of properties.

+ General move away from accepting specific keyword arguments to class 
  constructors, in favor of accepting property values instead.

    ===== UI Tier =====
+ Began work getting grid cell properties set up. IOW, being able to set the
  ForeColor of a specific row in a column (a single cell), including
  dynamic cell properties. Currently, it works, but the only property
  I've added yet is CellForeColor and DynamicCellForeColor.

+ Removed the requirement that objects used as DataSources have to inherit 
  from dObject. Thanks Carl for pointing out the limitation.

+ Added dDockForm to the main trunk, which is Dabo's wrapper for wxAUI. 

+ Added the option of passing complex filter expressions to setAll(). This 
  function now accepts a tuple of filter expressions of the format 
  'att comp val', which will be eval'd with the child objects inn order to 
  determine if the filter applies. Each expression in the tuple is ANDed 
  with the others; all the tuple elements must evaluate to True for the 
  value to be set.

+ Added the dHtmlBox.HtmlLinkClicked event.

+ Added the HatchStyle property to draw objects. This gives you the option 
  of specifying that the fill for drawn objects can be one of the following 
  hatch patterns:

    Solid (default)
    Transparent
    Cross
    Horizontal
    Vertical
    Diagonal
    ReverseDiagonal
    CrossDiagonal

+ EasyDialogBuilder - minor improvements by Nate Lowrie.

+ Added ensureLineVisible() method in dEditor, which even unfolds if needed.

+ Added WordWrap to dGrid columns while in edit mode.

+ Enhanced dShell to have Dabo property access, including Font properties.

+ Improved dDateTextBox.

+ Coerce dMessageBox messages into strings, which is convenient.

+ dGrid's navigation now traps and responds to business rule violations, with
  mediation by the form if possible. 

+ dTreeView supported in ClassDesigner-designed files.

+ Added Icon property to dApp, which will become the default Icon for all
  forms and dialogs, if not overridden at the form level.

+ Simplified drag/drop in dabo.ui.

+ Added dabo.ui.getChoice() and getChoices(), which present a list of choices
  to the user, and return the user's selection(s).

+ Added TextLength property to dTextBox, to limit the number of characters
  that can be typed in by the user. Courtesy Nate Lowrie.

+ Improved font zooming. Improved handling of resizing fonts for different
  platforms (Mac), so that you have cross-platform consistency. Thanks to
  Dj Gilcrease for help in working this out.

+ Added Continuous property to dSlider, which determines whether Hit is 
  raised while the slider is being changed, or only after the user has
  finished sliding.

+ Improved autocompletion in dEditor.

+ Added AutoAutoCompletion option to dEditor.

+ Added methods to dabo.ui: isMouseLeftDown(), isMouseRightDown(), 
  and isMouseMiddleDown().

+ Added tango icon theme and changed our toolbars/menus to reference the new
  icons. (Ticket # 1037)

+ Added Modal property to dForm, settable only by sending the property to the
  constructor. When Modal, a dialog instead of a form will be instantiated.

+ dEditor now properly syntax-colors dabo-based xml files such as .cdxml
  and .rfxml. Previously, it displayed these files using Python coloring.

+ Removed IconBundle property from dFormMixin. Added the ability to set Form.Icon
  to a sequence of filenames which Dabo will convert to a wx.IconBundle
  automatically.

+ Added property WordWrap to dEditBox. Default is True.

    ===== Data Tier =====
+ Added the option of passing additional keyword arguments to db.dConnection.
  Thanks Uwe for noting the limitation.

+ dbFirebird - Minor improvements by Uwe Grauer.

+ dbPostgreSQL - Improvements by John Fabiani, including some missing data
  types and support for schemas.

+ Added support for SQL-JOIN clauses in the sql builder.

+ Added database logging, an optional feature.

+ Improved SQLite by providing DictCursors.

+ Added enclosing of table, field, and other names in the appropriate quote
  character for the database backend in use. This allows for cases such as
  spaces in field names. Control whether quoting happens automatically using
  the dBizobj.AutoQuoteNames property.

    ===== Bizobj Tier =====
+ Added the concept of VirtualFields to dBizobj, which provides a simple,
  flexible interface to reference calculated fields on the fly.

+ Added the 'SaveNewUnchanged' property to dBizobj. When this is True, new 
  records that have not been modified from their defaults are saved; the 
  default remains to not insert such records. 

+ Improved data binding to bizobjs on a parent form.

+ Added dBizobj.deleteAllChildren()

+ Added ability to set parameters to pass to default values in dBizobj.

+ Added oldVal() method to dBizobj, which takes a field name and returns the
  value of the field at the time of the last requery.

+ Added moveToPK() method in dBizobj


Bug Fixes:
+ dRadioList.ButtonSpacing wasn't able to be set from initProperties() or
  as an argument to the constructor. Fixed.

+ Starting in wxPython 2.7, our dialogs weren't giving focus to the first
  control. Fixed.

+ More wxPython 2.8 bugfixes in dMenu, dPageFrame

+ Fixed dConnection and dConnectInfo to raise exceptions if improper
  arguments are passed. Ditto for dSizer*.

+ Fixed dBorderSizer's box to stay in back of the controls contained within it.

+ Fixed ForeColor to work immediately on Gtk.

+ Controls were flushing their value, and raising ValueChanged events, too
  many times. Fixed.

+ Dialogs and forms weren't able to set things like whether they have a 
  close box, from within initProperties. Fixed.

+ Message dialogs invoked like dabo.ui.areYouSure() weren't getting attached
  to the appropriate parent form, so that the message displayed wouldn't 
  activate the form that it applied to first. Fixed.

+ Fixed rapid flashing in a sorted dGrid when an editable column was selected.

+ Fixed bug that prevented adding new records when child bizobjs existed.
  (Ticket #1027). Thanks to Larry Long and John Fabiani for continued
  assistance in tracking these problems down.

+ setWhereClause() method missing in dBizobj. Fixed.

+ Fixed dCursor.getChangedRows() to not take into account new records that
  have no changes.

+ Fixed the dBizobj.save() process to not scan all child bizobj's repeatedly.
  This fixes some problems, and speeds up save() considerably.

+ Fixed a problem where canceling a bizobj that had no records caused an 
  exception that was being displayed with notifyUser(). Normally, a bizobj 
  with no records does not need canceling, so raising such an error is not 
  appropriate. You can still have the old behavior by calling cancel() with 
  'ignoreNoRecords = False'.

+ Fixed a bug reported by Larry Long and John Fabiani that involved requerying
  one bizobj resulted in checking for pending changes in other bizobjs that 
  were not involved in the requery.

+ Descending sorts created infinite loop with duplicate values. Fixed.
  (Ticket #1041). Thanks Jussi.

+ Fixed status text to clear the old field validation failed message when the
  user fixes the value and the field now passes validation.

+ Fixed the geometry persistence to only restore the size of the form from 
  user settings if BorderResizable is set to True. 

+ Fixed dGrid's AlternateRowColoring to be settable from the constructor
  or initProperties (previously, it was only settable in afterInit() or
  later). 

+ Dynamic props on dColumn were not working: fixed.

+ Fixed a bug that confused the string 'None' with the null value None when 
  setting BorderStyle from a cdxml. Thanks to Miguel for catching this one.

+ Fixed a couple of bugs related to the dSizer.BorderSides property. 
  Previously it was not retrieving that property correctly from the internal 
  wx flag.


===============================================================================
Dabo 0.7.2 (2007-01-18) (Revision 2716):

Additions, all minor, backported to stable only to keep compatibility with the 
stable versions of daboide and/or dabodemo:
+ Enhanced the getImagePath() function to work better with Windows pathing.
+ Refactored dPanel into a common mixin class.
+ Added getBaseNodeClass() function to dTreeView.

Bug Fixes:
+ Fixed the stable branch to work with wxPython 2.7 and 2.8, which was a fairly
  large backport of relevant changes from the development trunk.
+ Fixed a form activation problem that would happen in some cases on Windows, 
  particularly with the Class Designer.
+ Fixed incremental search in dGrid, which was broken by earlier unicode fixes.
+ dBizobj.onSaveNew() user hook never being called. Fixed.
+ Fixed but in dUserSettingProvider if setting/retrieving nested settings.
+ dForm not updating field values after a save(), which is sometimes needed.
  Fixed.
+ Fixed dForm to explicitly cancel bizobj changes if the user answers "no" to
  the "do you wish to save?" message. Otherwise, the application would never
  finish.
+ Fixed dGrid and dImage's attProperties.
+ Fixed bug in dGrid.HeaderHeight resulting in a traceback if you tried to set
  it in initProperties() or as a kwarg to the constructor.
+ Fixed dabo.ui.busyInfo() to actually show the specified text instead of just
  an ugly grey box on Gtk.
+ Fixed a bug in dbFirebird that was caused by initializing more than once.
+ Fixed a problem with the date textbox in the datanav select page adding 1
  to each month, resulting in an incorrect select statement.
+ Fixed some minor wording and behavior problems with the Quick Report option
  in AppWizard apps, thanks to Ted Roche.
+ Fixed htmlAbout to not return the html tags to the clipboard.
+ Fixed dToggleButton to always flush its data, not just on LostFocus.


===============================================================================
Dabo 0.7.1 (2006-11-21) (Revision 2490):

Bugfixes:
+ Segfault in dSplitter when dragging the sash. Fixed.
+ __init__() of the wx classes happening twice. Fixed.
+ Setting Caption sometimes required a subsequent refresh(). Fixed.


===============================================================================
Dabo 0.7 (2006-11-16) (Revision 2464):

It has sure been a while, but we haven't been resting. Lots of new stuff
as we move one step forward to Dabo 1.0. Here are the most important
things to mention.

Notable things:
+ SQLite is now required.
+ wxPython 2.7 and 2.8 DO NOT WORK yet, but will soon, so stick with 2.6
  for now.
+ Dabo preferences are no longer saved in .ini files, but as sqlite databases.
+ The old shortcut of referencing fields in bizobjs like:
    fname = biz.first_name
  no longer works. You need to change all such code to read:
    fname = biz.Record.first_name

Known Issues:
+ FireBird Requery problem (see http://dabodev.com/tracker/0229)


Bug Fixes:
+ Replace function in dTextBox and dEditBox causing traceback. Fixed.
+ Incremental search in dGrid now works with unicode data.
+ Double select page on Mac and Win. Fixed.
+ Datanav select page scrollbar doesn't show. Fixed.
+ Ignore Tab and Shift+Tab in grid searching, so they can navigate.
+ Setting AutoPopulatePK on the bizobj doesn't propagate to cursor. Fixed.
+ Entering a unicode character in a dTextBox set up with a str value doesn't
  stick. Fixed.
+ Fixed unicode problems in dEditor.
+ Fixed problem where fast cpu's could generate non-unique object names.
+ Fixed showModal() to reactivate previously deactivated windows accordingly.
+ dCursor's initProperties() called twice. Fixed.
+ Spacers not working correctly in class designer generated files. Fixed.
+ Fixed dabo.ui.getMouseObject() to always return the dabo object, not the
  wx one. This would happen with grids, for example.
+ Border sizer caption not showing. Fixed.
+ Connection information not properly escaped in default.cnxml. Fixed.
+ Fixed layout of nested sizers.
+ Fixed running class-within-a-class (class designer generated).
+ Fixed paged controls to work when generated from the Class Designer.
+ Grid mouse events duplicated. Fixed.
+ Can't set RegID from within initProperties(). Fixed.
+ stderr and stdout not restored if intellisense processing caused exception.
  Fixed.
+ Fixed login form to look okay at low resolutions.
+ Removed old, lingering requirement for mx.DateTime.
+ dSpinner doesn't work correctly unless initialized to '0'. Fixed.
+ dForm.ActiveControl would return controls in other forms, if they were the
  current active control with keyboard focus, when clearly we want the active
  control of *this* form. Fixed.
+ Fixed function in dbSQLite to find and set the pk field.
+ Fixed __version__.py to work outside the expected directory naming
  structure.
+ Report writer wasn't initializing report variables before starting the 
  iteration of the cursor, resulting in errors if you referred to the
  variables from inside the page header, for example. Fixed.
+ Setting the Value of a data-bound control programatically wasn't propagating 
  to the underlying bizobj. Fixed.
+ New reportlab can only handle utf-8, causing errors otherwise. Added a
  friendly message in case this happens to you when running the Quick Report
  option in AppWizard-generated apps.

Enhancements:
+ Added Visible property to grid dColumns.
+ Added column information to the EventData of grid events.
+ Removed RequeryOnLoad property from datanav.Form to dabo.ui.dForm.
+ Can now send kwargs to grid.addColumn(), which get sent to the column's
  constructor.
+ Added self.super() to replace cls.doDefault, thanks to Timothy Delaney.
+ Added exception handling to requerying. If exception happens, the
  transaction will be rolled back.
+ Enhanced the process used to determine field types. In addition to better
  automatic deduction of types, you can now explicitly set the DataStructure
  property of dBizobj and Dabo will respect that.
+ Added Alt+Up and Alt+Down to AppWizard Apps, which bring you to first and
  last records, respectively.
+ Added properties for getting/setting the selection and insertion point for
  text controls. These are InsertionPosition, SelectedText, SelectionEnd,
  SelectionLength, and SelectionStart.
+ Compound primary keys can now be used.
+ Dabo icon now has an alpha channel and looks much better. Thanks to Kenneth 
  Ismert for doing a great job of this.
+ Added Expanded property for treeview nodes.
+ Can now set PageClass property of dPageFrame to a cdxml file.
+ Added dRadioList to replace dRadioGroup. Pure Dabo control.
+ Added ability to set a bizobj LinkField property to a table.field reference.
+ Added RequeryWithParent property to dBizobj, True by default. Allows for
  user code to determine when to requery the child, for performance reasons.
+ Added Selection property to dGrid, which returns the list of selected rows
  or columns.
+ Added AutoBizobj, thanks to Echo.
+ Added Count property to dMenu, to return the number of child menus.
+ Changed most initial dEditor settings into configurable properties.
+ Drag/Drop for tree nodes begun.
+ Added getCurrentRecord() that returns the actual record data.
+ Added dPref for managing application preferences, and switched the default
  way to save/restore settings to use this class. Your application can define
  whatever hierarchy you see fit. See also the new BasePrefKey and 
  PreferenceManager properties of dObject.
+ Added ForceCase property to dTextBox and dEditBox. Forces to upper, lower,
  or title case as the user types.
+ Added getTempCursor() to facilitate ad-hoc data queries.
+ Added dApp.Encoding property, a single place to get the unicode encoding. To
  set the default encoding, use dabo.defaultEncoding = "latin-1", for example.
+ Added clear() method to sizers, to remove all items from the sizer, and to
  optionally destroy the items as well.
+ Added Precision property to dColumn, which specifies the number of places to
  show for float columns.
+ Added preliminary support for BLOB fields. Works at least with MySQL.
+ Added GridBeforeSort and GridAfterSort events.
+ Added itemNode entry to the eventData for Tree events.
+ dToggleButton now uses GenBitmapTextToggleButton, allowing for text and
  images.
+ Added some filtering functions to dDataSet, for selecting which records
  to return.
+ Added transparency and drawGradient to drawing objects. Thanks to Andrea
  Galvana for the gradient code.
+ Added WordWrap property to dColumn, which will wrap the text appropriately.
+ Added cut/copy/paste hooks at the grid level.
+ Added dabo.ui.getFormMousePosition (position relative to active form)
+ Added DrawMode property, the logical function to use for draw operations.
+ Added ability for About dialog subclasses to add their own version info.
+ Added helper functions to dabo.ui: isControlDown(), isShiftDown(), 
  isAltDown(), and isCommandDown() which will return True/False depending 
  on whether the key is down while the call is made.
+ Added containerCoordinates() and formCoordinates() method, to get the 
  current mouse position relative to the container or form.
+ Added objectCoordinates(), which is relative to the object.
+ Made dForm.ActiveForm settable as well as gettable.
+ Added isContainedBy() function, returning True if the object is contained
  inside the passed container.
+ Made dEditor a data-aware control (cool!)
+ Added Encoding property to dDataSet. Thanks to Simen Haugen.
+ Can now send extra keyword args to bindKey(), which will get included in
  the eventData dictionary, just like it works with bindEvent().
+ Added Dabo data type code "L" for blobs, "G" for longs, and "F" for floats.
+ Added 'sort none' option to dGrid. Now, the third mouse click on the header
  will be 'no sort'.
+ Added accelerator keys to the datanav Actions menu. Added Select All to the
  Edit menu.
+ Added dabo/ui/uiwx/concordance.py, which shows a listing of all the Dabo
  ui classes, and the wx Class from which they descend. Then, it shows the
  wx classes, and the list of Dabo classes that descend from it. Should help
  people with questions like "where is wx.TextCtrl in Dabo? (dTextBox).
+ Added MultipleSelection property to dGrid.
+ Improved dPageList, allowing setting the spacing of the list items with
  ListSpacing, and catching right-clicks smartly (the correct item gets 
  referenced).
+ Added function dabo.lib.getRandomUUID(). Thanks to Ka-Ping Yee.
+ Added method afterInitAll(), which gets called after all child objects have 
  been initialized and are live.
+ Added helpful treeFromStructure() method to dTreeView, which takes a
  hierarchy (in list or tuple form) and constructs the tree nodes accordingly.
+ Added ability to send sequences of 3-sequences to the ok/cancel dialog to 
  automatically construct labels and controls on the dialog.
+ Couldn't use the same RegID for objects, even if the prior object was
  destroyed. Relaxed the requirements to allow for this.
+ Added dHtmlBox, which wraps wx.html.HtmlWindow, for displaying formatted 
  text simply. Thanks to Nate Lowrie.
+ Added showContainingPage() method to all ui controls, which will recursively
  show any pages in any pageframes that contain this control.
+ Added showCurrentLine() to dEditor. Does what it says.
+ Datanav forms (AppWizard-generated) now look better as they have a bigger
  default size. Thanks to Bill Anderson for bringing up lots of such issues.
+ Added AddChildEditPages property to datanav apps. Set it to False and you
  stop getting the annoying edit pages for the child bizobjs.
+ Previously, you could only set page sizes in reports to strings like 
  "letter", "a4", etc. Now, you can also set explicit sizes such as
  (100, 75) or ("1.75 in", "1 in").
+ Added preliminary support for Microsoft SQL Server. This isn't usable yet 
  for any but the most tenacious developers, and likely quite buggy. If you 
  want to try it out or help develop it, please post a message to the dabo
  developer's list (dabo-dev@leafe.com). 


===============================================================================
Dabo 0.6 (2006-03-27) (Revision 2043):

+ Fixed a problem when switching to the Browse page of the datanav grid without
  first running a query. Also, there was an error being thrown if a previous
  query had results, and a subsequent query had no results.

+ Modified the code in _setCurrentRow() of dGrid so that it wasn't calling
  SetGridCursor() unless the position had actually changed. I had recorded up to
  10 calls to this function, all with the exact same values each time I switched
  to the Browse page.

+ Removed the code that lower-cased field names, as it was preventing the code
  from working with case-sensitive backends and columns containing capital
  letters.

  Fixed a problem where str values were not able to be properly converted to
  unicode.

+ Added a parameter to the promptForFileName() method to specify the default
  path for the dialog.

+ Added the TreeItemContextMenu event. This differs from the normal
  ContextMenuEvent in that it returns the itemID of the node that was 
  right-clicked.

+ Added code in the event data gathering code to store the tree item ID for
  these events in EventData.itemID.

+ Changed all the names '_id' in the dTreeView.py file to the clearer 'itemID'.

+ Fixed an oversight in the dSizerMixin that didn't remove the Box for a
  dBorderSizer when the sizer was released.

+ The double-Activate on Windows is really getting in the way. I haven't heard
  anything from my bug report yet, so I added workaround code to ignore the
  first Activate.

+ Cleaned up the order of releasing child objects for sizers. Also fixed problem
  with releasing the box for border sizers.

+ Added getFunctionList() method to return a list of all 'class' and 'def'
  statements in the current file.

+ First pass at integrating the dTable class into the dabo.db framework. Right
  now, if this works at all, it only works for SQLite.

+ Fixed a bug wherein multiply-nested sizers might not release all of their
  content when release(True) is called.

+ Added a 'setInactive()' method that will hide the auto-complete popup if one
  is visible.

+ Disabled the fillGrid()'s setting of focus to the grid, as it causes problems
  with stealing focus away from another active form, at least on Windows. Also,
  it seems that such code really doesn't belong inside the function to build the
  grid, but perhaps we'll find it belongs somewhere else.

+ The xml header wasn't being converted to native line endings. Fixed.

+ No need to explicitly do the unicode conversion in the report fields, as that
  is done in the report writer.

+ Added a Refresh event. This is raised when dForm.refresh() is called. All
  dPemMixin classes will receive it, and fire their refresh() hook method.

+ Added dynamic properties to most normal static properties. Example: given a
  label and a function 'currTime()' in a form that returns the current time,
  issuing the following:
    label.DynamicCaption = label.Form.currTime
  will result in the label's Caption property being updated every time
  label.Form.refresh() is called.

+ Added two methods to dabo.ui for converting image data back to bitmaps and
  images. These were necessary because I noticed that when Editor.py was called
  from locations other than its own directory, the image file for the function
  button was not found. The solution was to convert the .png file to a data
  stream using wx.tools.img2py.py, and store that in Editor.py.

+ Can now set dApp.UI=None, and setup() won't try to load a UI. You have to do
  it explicitly, though, such as:
    app = dabo.dApp()
    app.UI = None
    app.setup()
  --or--
    app = dabo.dApp(UI=None)
    app.setup()

+ First crack at creating a double-buffered drawing surface. The new class,
  'dDrawPanel', is a subclass of dPanel, but has its repainting handled through
  the double-buffer techniques outlined on the wxPython wiki.

+ Bookmarks in dEditor now persist when you save the file. If you re-open a
  saved file with bookmarks, they are restored.

+ Refactored dUserSettingProvider a little bit. Fixed a bug in 
  getUserSettingKeys() that resulted in it always returning an empty list. Added
  deleteUserSetting() and deleteAllUserSettings(); these do just what you think
  they would.

+ Changed a couple exec() calls to setattr() calls instead, which may be safer 
  if not faster, but definitely more explicit and easier to understand.

+ Implemented the handling of RowSpan/ColSpan for grid sizers.  Added a
  GridSizerSpanException class that is raised if an attempt to set the span to a
  location that is already occupied.

+ Revamped the entire flow for transactions. These changes have been tested on
  MySQL and SQLite, but still need to be tested with Firebird and PostgreSQL.

+ Changed the default for bizobjs, cursors, etc., to not autocommit. The
  AutoCommit property of the bizobj is simply a pass-through to the cursor's
  AutoCommit property.

+ Also cleaned up some inconsistent spacing and method ordering.

+ Modified datanav to allow for manual setups that don't use fieldSpecs or
  relationSpecs. I'll be committing a change to the AppWizard that allows
  for this option soon.

+ Moved SelectPageClass, BrowsePageClass, and EditPageClass from PageFrame
  to Form, since that is a better central location for these properties.

+ Added a splash screen to the Dabo app startup. This is based on Andrea 
  Gavana's AdvancedSplash class, and allows for cool shaped windows, etc.

+ Added the ability to set the DataSource to an object, rather than just a
  string that can be eval'd to an object.

+ Changed the 'getMaxRow/Col' methods to 'getHighRow/Col' in order to avoid
  confusion with the MaxRows/Cols props in dGridSizer.

+ Modified both sizer classes to accept windows and not just SizerItems when
  setting/getting prop values.

+ Added the movePage() method, which takes either a page reference or a page
  index, and moves the page to the specified position. The page is then
  selected, unless the third parameter 'selecting' is False.

+ Added a getInt() method to dabo.ui.uiwx.

+ Fixed the splashscreen display on Windows.

+ Added the ability to set the font face and size for the editor.

+ Added the setCheck() method to dMenu. Given a caption, it will check any menus
  whose captions match. By default it will uncheck any that don't match; you can
  pass False as the second argument and leave non-matchers alone. Also added
  clearChecks() to uncheck all menu items in a menu.

+ Exposed the FileName and FilePath properties in dEditor.

+ Added some syntax sugar for referring to fields and variables in reports.
  Where you used to have to refer to self.Record["clientname"], you can now do
  self.clientname. Same with self.Variables.

+ Added the 'callEvery' function to dabo.ui. This function accepts an interval
  (in milliseconds), and callable reference, and optional arguments to that
  callable. It then creates a timer that fires the callable every <interval>
  milliseconds, passing along any optionally included arguments. The timer
  reference is then returned, where it can be controlled by calling stop(), 
  start() or release(). This is based on the dCallEvery class that Brandon
  Singer proposed. I made it a function in dabo.ui because I felt it was more
  consistent with the existing functions callAfter() and callAfterInterval().

+ Changed the default for forms to not automatically show "Record 1 of 0" or
  similar meaningless database information in the status bar. Set it back to
  True for the datanav Form class, so all datanav apps should remain unchanged.
  All of the apps in the demo and IDE directories that don't query data, though,
  no longer show that message.

+ Creating an instance of dApp doesn't automatically create an instance of
  uiApp. Instead, it now asks dabo.ui to get it a reference, and dabo.ui either
  returns the current instance if one already exists, or creates one if not.
  This allows you to run wxPython apps from within wxPython apps.

+ Added some rudimentary support for file drag/drop. Right now, you can call
  'createFileDropTarget' on an object to make it able to respond to files
  dropped on it. Pass in an optional handler object reference; otherwise, the
  handler is set to the object itself. The drop event is passed on to the
  handler by calling its 'processDroppedFiles' method, which should be
  overridden in the handler object to do the specific processing of the files.

+ Added a 'Column' property to dEditor; this represents the column position in
  the current line, and can be changed to move the cursor within the line.

+ Added option in getItemByRowCol() to return the sizer item in the given
  position instead of the object managed by that sizer item.

+ Added method 'isItemChecked()' to allow you to determine the checked status of
  any menu item.

+ Added dabo.ui.getMousePosition(), which returns the position of the mouse
  on the screen. This is in contrast to dPemMixin.getMousePosition(), which 
  gets the position of the mouse inside the client window.

+ Update to allow execution of SQL statements without affecting the current data
  set. The bizobj has a new pass-through method named 'execute()', which takes a
  statement understood by the backend database and passes it to its cursor's
  execute method.

+ The cursor class has been modified to run all statements that don't begin with
  'select' through its auxiliary cursor, thereby preserving its data set.
  Preliminary tests that I've run have confirmed that these are working
  correctly, but there should be a lot more testing done before I am confident
  that these changes are truly sound and can handle whatever we can toss at them.

+ You can now set the DataSource to an actual object, instead of having to set
  it to a string that could be resolved to an object. 

+ Added basic support for storing lists/tuples in the user settings. 

+ Added a simple way of persisting MRU lists in applications. A new dApp
  property, '_persistentMRUs' is a dict that contains the name of the menu as
  the key for the entry, and the function to bind the items to as the value. The
  framework will then handle saving and restoring MRU lists upon app startup and
  closing.

+ Modified the uiApp to accept just the menu caption as an identifier instead of
  requiring the actual menu. This is necessary to create MRU lists for context
  menus, or for restoring menus at app startup.

+ Updated the requirement that a bizobj be found for all data sources. Since
  that was written, Dabo's use of data binding has expanded to lots of 
  non-bizobj uses.

+ Completed the majority of the work needed to implement saved classes that can
  be used in other class designs; it was working from the Designer, but not when
  you ran the form. These changes implement the whole inheritance structure so
  that if you change the underlying class, any changes not explicitly overridden
  in the design that uses that class are reflected. This works for both property
  changes as well as code changes. 

+ Switched the default order of arguments in callAfterInterval(). It makes more
  sense to specify the interval first, followed by the function and its
  arguments. Sticking the interval between the function and its arguments seems
  very awkward. I added code to callAfterInterval() to check if it received a
  call in which the interval is the second argument (i.e., the original style)
  and switch them around in that event.

+ Removed dDrawPanel as a class. Turns out that adding double-buffering to
  panels doesn't affect their performance noticeably, so it made sense to turn
  this on for all dPanel objects by default. However, if you run into a
  situation where this adversely affects your app, there is a new property named
  'Buffered' that will turn this behavior off (i.e., make it work like it used
  to) when set to False.

  *IF YOU USED dDrawPanel IN YOUR CODE, THIS WILL BREAK IT!* You must update by
  changing all references to dDrawPanel to simply dPanel.

+ Removed the old syntax for begin/commit/rollbackTransaction. The default for
  these actions in dBackendObject is to call the appropriate method on the
  connection, not to execute a command on the cursor.

+ Removed the call to cursor.connection.begin() in the beginTransaction()
  method. This does not seem to be needed for most backends; in fact, it is
  typically used to override autocommit to create temporary explicit
  transactions.

+ Table creation now works for MySQL also. The class dAutoBizobj is a bizobj
  that has a dTable. The function AutoCreateTables() will try to create all the
  tables that have been setup with dAutoBizobj objects. If it can't create the
  tables, a message pops up for the user and the db admin. The db admin can
  enter the username and password for access to create tables or the db admin
  can manualy execute the queries in the queries.sql.

+ Converted the dTimer from a bitmap to a non-visible control based directly on
  wx.Timer. This makes it fit in much better with dabo.ui.callEvery(), which is
  much more convenient to use in many cases.

+ Began coding for the Hover property, which will allow for easier visual coding
  of MouseOver events. It isn't fully implemented yet, so don't try working with
  it.

+ Implemented the Hover property in dPemMixin. The reason for this rather than
  relying on MouseLeave to terminate the effect is that there are many time when
  it seems that the mouse leaves the area without triggering the MouseLeave
  event. The Hover mechanism employs a timer to check for mouse position, and
  fire the MouseLeave code if it detects that the mouse position is outside of
  the control.

+ Added a CustomSQL property to the datanav form. If set, the settings in the 
  select page will be ignored and the contents of CustomSQL used instead.

+ Added defaults to dGrid.getValue(). If no row or col is specified, it defaults
  to the current row/column, respectively.

+ Added fontMetricFromDrawObject() to dabo.ui. This enables simple calculation
  of the width/height of a drawn text object.

+ Added a fitToSizer() method to dPemMixin. This will resize the object to fit
  the size required by the sizer represented in its Sizer property. You can also
  pass in extraWidth and extraHeight values to adjust the size further.

+ Added 'Alignment' to the pre-init properties of dCheckBox. Cleaned up the
  property methods and definitions to make them alphabetized, and to make the
  strings localized. Also relaxed the values accepted for the Alignment 
  property.

+ Added an option to dEditor.changeFontSize() to accept strings in the format
  "+n" or "-n". These will increment or decrement the font size by 'n' points.

+ Moved the _addCode() method out of dFormMixin, since it really is more generic
  than that. It now lives in dObject._addCodeAsMethod(), which takes a dict of
  method name/code pairs and adds them as methods of the object. dPemMixin now
  looks for a keyword argument called 'srcCode', and if found, adds it to the
  object.

+ You can now call addObject() and pass a cdxml file instead of a Dabo class
  reference, and the class defined in the cdxml will be added to the parent.

+ Cleaned up the dynamic code creation routines in dObject and
  DesignerXmlConverter.

+ Modified xmltodict to handle property declarations.

+ Added setAfter() and setAfterInterval() to dabo.ui. These work the same as
  callAfter() and callAfterInterval(), except you use them to set properties to
  particular values.

+ Added the following properties to dGrid: MovableColumns, ResizableColumns, and
  ResizableRows. When any of these are set to False, the user cannot move/resize
  the column or row.

+ Changed the keyboard datanav navigation from Ctrl+, and Ctrl+. to Ctrl+LEFT 
  and Ctrl+RIGHT on Mac, and Alt+LEFT and Alt+RIGHT on Linux and Windows. I've
  The original configuration, in addition to being nonintuitive, didn't work on
  Windows.

+ Added the ability to save screenshots in one of several graphics formats.
  While this was part of the Bubblet demo originally, it could have uses
  elsewhere. For example, combining this with dabo.ui.callAfterInterval() would
  enable timed screen shots.

+ Hacked a bit to get getCaptureBitmap() to work well on GTTK, but it's still
  a bit of a mess. GTK doesn't capture the title bar, menu bar or frame
  decorations of a window, and I tried to compensate the sizing accordingly.
  Individual controls don't seem to work at all. I don't have more time to
  play around with this now, but this is hardly a show-stopper for release.


===============================================================================
Dabo 0.5.1 (2006-01-25) (Revision 1860):

+ Additional MDI/SDI improvements and fixes. By default, dForm on Windows will 
  be a MDI child, which is what most Windows users will expect.

+ Fixed PageFrame background color to take the background color from the form,
  not unconditional white. Only on Windows - Gtk and Mac do the right thing by
  default.

+ Fixed various issues with getting icon files and converting them to bitmaps.

+ Set the default grid font to Arial,9 on Windows, as the wx-default was just
  plain ugly.

+ Added getPositionInSizer() method to sizers, since they may also be contained
  within sizers.

+ Reworked dShell. Now it appears as a split window, with the standard command
  area on the top, and the output in the lower pane.

+ Changed dGridSizer to raise an exception if the insert method is called
  instead of just returning False.

+ Added SashPositionChanged event. Updated dSplitter to raise this event when
  the sash position changes.

+ Added scrollToBeginning() and scrollToEnd() methods to dEditBox.

+ Added pass-through properties for dSplitForm's splitter's panels.

+ Added the property 'SplitState' to the dShell class. By right-clicking on the
  shell, you can toggle between the new split behavior and the "traditional"
  single pane behavior.

+ Added a right-click menu to the output pane. Right now all it can do is clear
  itself, but we could add other stuff such as font selection, etc.

+ Fixed a bug in uiApp that prevented Cut(), Copy() and Paste() from working in
  the shell (and other non-Daboized controls that only have wx versions of these
  methods).

+ Added a menu command to the shell to clear the output window using 
  Ctrl-Backspace.

+ Added the MenuOpen event to dEvents. This allows us to create dynamic menus by
  intercepting this event and updating the prompts of the menu items as needed.
  Added the event data code to save the prompt and menu object that triggered
  the event.

+ Added 'deadObjectException' as an alias to wx._core.PyDeadObjectError to the
  dabo.ui.uiwx module. This will enable Dabo code to handle this condition
  without having to use wx code.

+ Added a bunch on internationalization to the dShell script.

+ Made the dMessageBox titles come from Application.getAppInfo(appName) by
  default.

+ Added handling for situations where a bizobj is used with a data connection.

+ Added a sizeToColumns() method. This will set the width of the grid equal to
  that of its component Columns.

+ Fixed copy to clipboard in about.py to use CRLF on Windows.

+ Added new properties to grid:
    HorizontalScrolling
    VerticalScrolling
    ShowColumnLables
    ShowCellBorders
  The scrolling properties are booleans, and will hide/show the scrollbars.

+ Fixed some problems with setting the column's Width. For a number of reasons,
  when you created a grid from scratch and then added columns using addColumn,
  the columns widths you'd specify weren't being respected. Fixed.

+ Moved the code for the dEditor class from ide/dEditor.py into its own 
  uiwx-level class. This will allow other apps (I'm thinking Designer here!) to
  instantiate code editors where they need.

+ Revamped the layout of the dOkCancelDialog class to create the panel and sizer
  that is needed in addControls().

+ Cleaned up some of the default spacing so that with AutoSize=True, the form
  still looks OK.

+ Removed the split sash code from the dEditor. That stuff belongs in the form
  the editor is located, not in the editor itself.

+ Fixed a bug in dGrid that only seemed to pop up when the grid was located on a
  form with a bizobj but that wasn't a dForm. The presets dialog in minesweeper
  fit that description, and it was throwing errors when you navigated through
  the grid.

+ Added methods for getting/setting the back color of individual items.

+ Added property CellHighlightWidth to dGrid, and used that property in the
  about dialog.

+ Made dPanel.addControls() better behaved.

+ Reworked/improved the Quick Report dialog in datanav.

+ Updated dPageFrameNoTabs to raise the same events as the 'tabbed' versions do.
  Added a 'getPageNumber()' method.

+ Added PNG files for rotating images clockwise and counter-clockwise.

+ Improved dImage to support 90 degree rotation in either direction. Added
  rotation to the the demo.

+ Fixed a bug in dListControl's StringValue prop, and any other place where the
  framework was trying to call the control's GetString() method, since it
  doesn't have one.

+ Added SearchDelay property to dApp, which becomes the default SearchDelay for
  dGrid. The dGrid SearchDelay can get set to any int but that won't override
  the dApp setting. If dGrid.SearchDelay is set to None (the default), that is
  when the dApp setting gets used. Set the default SearchDelay to 300 - better
  than the previous 600 IMO but still not too fast. Eventually, when we provide
  a default system preference screen, we should expose this property for the
  user to tweak how they like.

+ Cleaned up and consolidated lots of stuff in dGrid, which shouldn't have any
  effect on runtime performance. Made SameSizeRows into an actual property.

+ Using the standard button sizer in the okay/cancel dialog is good, because it
  lets wx handle the platform-convention rules. However, even though it handles
  rearranging the order of the buttons as needed, it doesn't rearrange tab
  order. So I added code to do that.

+ Reworked the login dialog to subclass from dOkCancelDialog.

+ Reworked dGrid to sync the rowcount in refresh() calls. Fixed bug in syncing
  of column counts.

+ The entire populate() cycle was happening every time you entered the browse
  page in datanav apps, when in reality the only thing you need to do in current
  dGrids when the dataset has been requeried is a simple refresh().

+ Added an initial call to _clearDocument(), which is where all the defaults are
  set for the editor. The DesignerEditor would not indent properly without this.

+ Added moveToBeginning() and moveToEnd() methods to position the pointer at the
  beginning and end of the document, respectively.

+ Added functions to dBizobj, dCursor, and dBackend to get the data structure
  from the cursor description, instead of querying the backend based on a table
  name. This is more likely to contain correct information, but will need work
  for other backends besides MySQL. Also, getting the pkid is still problematic
  - but IMO it isn't a big deal to just have the user tell us which field to use
  as the PK.

+ Fixed dGrid's buildFromDataSet() to use the new function so it will work even
  if the bizobj has no records at the time of creation.

+ Fixed dGrid.sort() to not care if sort is done on an empty bizobj. Added the
  logic to restore code saved in the Designer so that it functions properly in
  the re-created form.

+ This is big - really big. For the first time, you can create a form in the
  Designer, add code to be bound to events, or create custom methods, and that
  code will work in the form created from the .cdxml file exactly the same as if
  you had written those methods in a regular .py script.

+ Improved the card deck pictures.

+ Fixed some problems in the Icon setter that would cause errors if None was
  passed, or if the icon path didn't exist, as would be the case if you were
  running with py2exe and didn't include the icon files as resources.

+ Added a significant change to eventMixin.py's auto event binding logic. The
  code now first looks at the object itself before looking up its family tree.
  This is critical for the event binding when running a cdxml file, where
  methods are added to the object at runtime, and are not present in the class
  definition.

+ Cleaned up some spacing in dEvents; also fixed some "appliesToClass" logic
  that had events 'applying' to incorrect classses. There are still some
  anomalies, I'm sure; the event listing in the Designer will reveal these.

+ Modified the dynamic code binding to fix the problem with modifying the
  object's class definition in the current namespace. Also fixed a problem where
  code for dPage objects was not getting assigned.

+ Fixed a bug in the dListControl's _getValue() method when there were no items
  in the list.

+ Added alias 'dragging' for 'mouseDown' in the EventData for mouse events.

+ Added method 'getMousePosition()' to dPemMixin. This returns the mouse
  position in relative coordinates to the object that called it.

+ Added 'drawBitmap()' method to dPemMixin. Like the other wx.DC drawing
  methods, this wraps the wx.DC.DrawBitmap() method into an object interface
  that Dabo objects can use.

+ Changed getSQL() so that if no FROM clause has been specified, it defaults to
  a FROM clause using the cursor's Table.

+ Added properties SettingsFileName and SettingsDirectoryName to the app's
  UserSettingProvider. The defaults for both come from 
  app.getAppInfo("appShortName"), and determine the name of the directory and
  file name of the user settings file. The directory name will be lower()'d and
  have a '.' prepended automatically.

+ Created the dFoldPanel and dFoldPanelBar classes, which wrap the built-in
  wx.lib.FoldPanel classes. Modified __init__.py to include these, and added
  some hacks to dPemMixin to enable them to work with the event structure.

+ Added the dCalendar control. This wraps the wx.calendar.CalendarCtrl, making
  it simpler and more Pythonic to work with.

+ Added a setting 'firstDayOfWeek' to dabo.settings

+ Moved the method _getWxColour() from dFoldPanelBar into dPemMixin, as it is
  needed in both dFoldPanelBar as well as dCalendar, and possibly other wx
  controls that expect a wx.Colour object instead of a color tuple.

+ Added the calendar events and their processing.

+ Added a form subclass named 'dBorderlessForm'. This creates a form with no
  visible border or title bar. Renamed the base form class in dForm.py from
  'dFormBase' to 'BaseForm'. I felt that the 'd' prefix was misleading, as it
  isn't meant to be a Dabo base class at all.

+ Updated dDateTextBox to use regular datetime values internally instead of
  wx.DateTime. Updated the calendar to use the new Dabo dCalendar instead of the
  raw wx version.

+ Added row and column highlighting to the dGrid class. Default is to only show
  the selected cell, but that can be changed by setting the SelectionMode
  property to either "rows" or "columns". The color used to highlight the
  selected row/col is controlled by the new SelectionBackColor and
  SelectionForeColor properties; defaults are yellow background and black text.

+ Added a GridRangeSelected event to dEvents, and added the code to raise it to
  dGrid.

+ Changed the default SelectionMode for the datanav grid to 'row'.

+ Added some additional properties and functionality to the dFoldPanelBar class.
  First is the 'Singleton' property, which controls a behavior in which one and
  only one panel is open at any time. Expanding a different panel collapses the
  currently open one, and attempting to collapse the expanded panel does
  nothing. 

  Second, there is a 'SingleClick' property that controls whether you need to
  double-click on a panel's caption bar (default behavior) to toggle it, or
  whether a single click will suffice.

  Finally, the 'CollapseToBottom' property determines whether any collapsed
  panels are positioned at the bottom of the control, or whether they remain in
  their natural position.

  I added the FoldPanelCaptionClick and FoldPanelChange events to dEvents in
  order to implement these features. They are available to instances of the
  dFoldPanelBar class for hooking additional behaviors to these events.

  I updated the test form for dFoldPanelBar to enable you to play with these
  settings.

+ Fixed a bug in dGrid's new SelectionMode property. I had previously checked
  for only 'r' or 'c' at the beginning of the setting, forgetting that 'cells'
  is a valid setting, so I fixed that to check the first two letters.

+ Added the property 'AlternateRowColoring' to dGrid. When True, rows in the
  grid will be colored depending on the RowColorOdd and RowColorEven properties.

+ Changed the datanav grid to use alternate row coloring.

+ Added some changes to the column Width setting that were necessary for working
  correctly in the Designer.

+ Fixed a bug with MultipleSelect in the dTreeView class. Added some navigation
  methods for returning adjacent nodes. Fixed a selection bug when working with
  MultipleSelect=True.

+ Added code to properly escape characters that should not be in XML attributes.
  Also cleaned up some uneven spacing in the created XML.

+ Fixed a bug in dGrid that didn't allow the ColumnCount to be reduced.

+ Fixed a bug in dPage that happened when the page was instantiated separately
  from the pageframe, since it wasn't yet in the Pages collection.

+ Added 'dEditableList', which is a wrapping of the wx.gizmos.EditableListBox.
  This control takes a list and allows the user to add/edit/delete items from
  the list, as well as re-order them. There are properties to enable/disable any
  of the following: edit, add, delete, order. All are enabled by default.

+ Fixed a bug in dGridSizer. Apparently, calling 'AddGrowableRow/Col' multiple
  times increments an internal counter, and a subsequent 'RemoveGrowableRow/Col'
  will only decrement it, and will not set it to be not growable unless the
  counter has dropped to zero. Now setting a row as growable won't do anything
  if it already is.

+ Added the drawText() method, along with the text draw objects.

+ Added columns to reportWriter. Added smarter sorting of elements in the xml
  output, for instance putting the report title up top instead of on bottom, and
  putting the bands in order that they appear and not alpha order.

+ Changed all the sizer routines to return the SizerItem managing the object
  that was just added to the sizer.

+ Sizer.Children now modified the SizerItem objects to include a
  'ControllingSizer' attribute that references the parent sizer.

+ Modified the dFoldPanelBar class to better time its refreshes. It's still a
  bit funky, but does seem to work better.

+ Modified dFormMixin to handle the new Spacer panels correctly.

+ Added a 'Children' property to dFoldPanelBar that returns the child panels,
  instead of the layout panel that it uses to manage the visible panels.

+ Added a return value to setItemProp() in the sizers so that we can tell if a
  value was successfully applied.

+ Fixed the problem with propertyHelperMixin.getPropertyList(): it was caching
  the list of properties across the class hierarchy, instead of caching just for
  this one class definition. Good catch, Ed!

+ Wrapped the wx.CheckListBox for Dabo.

+ Changed the parameter to sizer for setting the sides that the Border property
  applies to from 'borderFlags' to 'borderSides', as this seems much more
  appropriate. Updated the sizers to properly get/set this prop from a list of
  values.

+ Changed all hard-coded "\n" in dicttoxml to the more crossplatform idiom 
  "%s" % os.linesep.

+ Fixed a problem whereby nested sizers did not get their Parent property set.
  Thanks to Casey McGuire for catching this bug.

+ Added the GridCellEditBegin event, which is raised when a grid cell editor is
  shown. This allows you to record the value of a cell before it is modified by
  the user.

+ Added StayOnTop property to dFormMixin.

+ Added ShowMenuBar property, so I can avoid showing the Dabo menubar on my
  property sheet and object tree forms.

+ Added groups and variables elements to a newly created report form.
