//
// -----------------------------------------------------------------------
// TODO
// -----------------------------------------------------------------------
//

//
// For Next Release:
// * Third "unspecified" state to bool properties.
//
// Maybe later:
// * Fix MSW spinctrl indentation (using old tc indent fix)?
// * IntProperty min/max (automatic use: validator, spinctrl).
// * Python: Proper refcounting hack (regarding double incref)?
// * Python: Crash if not imported in global scope?
// * GetPropertyValue() to return Null wxVariant if the property value is
//   unspecified (uncomment code in GetValueAsVariant).
// * Key interceptor docs (remember GetGrid!).
// * Traditional wxValidator mode?.
// * wxPG_EX_ALTERNATE_KEYS?
// * Make various wxPropertyGridState methods virtual (SetPropertyValues).
// * Add pImpl.
// * GetPropertyAttribute
// * Fix Python SetValues Freeze-Thaw (regarding autofill=True).
// * Double-buffering to checkbox.
// * Increase consistency of OnResize (need better testing code/procedure).
//   One potential solution is to use, as someone suggested, a large panel on
//   wxScrolledWindow.
// * If wxParentProperty is loaded from a text source, its value should
//   be set *after* all children are inserted.
// * Enable font images?
// * After 1.0.x compatibility removed, drop itemcount argument support.
//
// 1.3 Branch:
// * onevent wnd always actual control, never clipper.
// * Custom values (one of which is Unspecified). Up to 255, use string table
//   in property grid for relevant displayed strings.
// * Maybe have wxPG_EX_PROCESS_EVENTS_IMMEDIATELY behaviour as default (and non-
//   optional).
// * Move to different directory style to enable CVS usage.
// * Integrate the flexible MVC grid backend.
// * wxPGId == wxPGProperty*
// * wxSize, wxDateTime, wxPoint returned as values instead of const Foo&
//   (so that empty values can be returned on invalid property).
// * Get rid of wxPG_COMPATIBILITY_1_0_0s.
// * Classnames = property names
//   Construction requires new then probably. The only way around
//   this would be a way too messy copying system.
// * IsPropertyXXX to const?
// * If child changed, send changed events for all related parents *as well*.
// * wxPGNameStr -> const wxString& (but retain typedef).
// * wxPGId -> wxPGProperty* (but retain typedef).
// * Change wxPG_SUBID1 etc to 1,2,3...
// * Have wxPG_EX_GREY_LABEL_WHEN_DISABLED as default.
// * wxVariant values.
//   * Would not eliminate need for DoSetValue and GetValue in
//     all cases (but would in most).
//   * Value type would do ValueToString and ValueToInt conversion.
//     Property ptr would be given as arg, so that int value type
//     could convert itself into a choice string at value's index.
// * Images in front of labels.
// * SetPropertyBackgroundColour instead of SetPropertyColour.
// * Replace SetAttribute with DoSetAttribute, and add SetAttribute as
//   user-usable method (currently there is only SetAttrib).
// * Get rid of priority system/compactor button (with compatibility defines,
//   however).
// * Real property attribute system.
// * String attribute names (old defines can be set to strings, so the
//   compatibility is kept).
// * Deprecate IsModified (in favour of IsPropertyModified).
// * Deprecate Disable.
// * HitTest.
// * SetPropertyTextColour.
// * Abstract wxPGEditorDialog scheme (longstringproperty and arraystringproperty
//   to support it, at the least). Probably needs an adapter class
//   (for validator support and such).
// * Replace FROM_STATE macros (but remember, it is redefined just prior to
//   state methods!!!).
// * wxPG_INVALID_VALUE to equal INT_MIN. Or not? Does it matter?
//
// High Priority but Difficult to implement or justify:
// * TAB should visit trigger buttons as well (but requires that wxButton or
//   its usage is properly fixed to support key event tracking.
// * Put kbd focus rectangle to check box, but only when focus really comes
//   from kbd.
// * Child priority system more consistent (ie. wxPGPWC vs wxPP vs wxCP)
// * Consider: move (some of the) example properties to headers.
// * Finalize: Font property images (drop down could use them as well, and even
//   in more useful manner).
// * wxMSW: Scrollbar freeze after mode switch (did resizing before that).
//
// For Some of the Next Releases:
// * Consider: Semi-unfocus on when clicking (l+r) on empty space.
// * Consider: Match system font size in grid.
//   Problem: There is no preferred font point size detection.
// * Multiple delimiters for string tokenizers (e.g. ';' in addition to ',').
// * Temporary object file etc folder and file removal on install and uninstall.
// * Consider: Further additions to wxPropertyContainerMethods
//   (virtual Insert, Delete and DrawItemAndChildren, and then methods
//   that need them). This could reduce size of wxPropertyGridManager
//   code.
// * Consider: three-argument wxEnumProperty (choices would be added
//     with AddPropertyChoice). Already has this, but with docs too.
// * Error/Warning popups (preferably a balloon tooltip on WinNT-based OS).
// * Consider adding optional images in front of property label.
// * Improve string editor dialog (but how?).
//
// Bug Fixes:
// * wxGTK, no cc: Right-click doesn't occur if right-clicked on control.
// * wxGTK, no cc: TAB-based editor browsing ceases sometimes (try 2nd page, until
//   two disabled boolprops).
//
// Medium Priority:
// * wxPropertyGridManager's missing methods:
//   GetLastProperty.
// * Adding items when focused is no-no.
// * Properly fix DoGetBestSize (both controls). How? It is called but
//   result is probably somehow interpreted incorrectly.
//
// To Consider:
// * Simple checkbox: Background clear unaligned (see with grey colour scheme).
//   Problem: It is caused by the MSW checkmark drawing background clear.
// * Remove hover support to lighten some code (no tooltips, then).
//   Would basicly eliminate need for visibility cache (get first visible
//   instead viscache refresh and find items around it).
// * Custom image horizontal size increment in relation to line height.
//   Feb-13-2005: Only real help if people use really big ( ptsz>12 ) fonts.
//   So this is real low priority.
// * At some occasions, maybe use FindOrCreatePen and FindOrCreateBrush.
//   Feb-13-2005: More bloat for marginal gains.
// * Key event forwarding (use ex flag to mark that).
//   Feb-13-2005: Really needed?
// * Visual state saving (which items are expanded and which collapsed,
//   which mode is selected).
//   Feb-13-2005: More bloat?
// * Manager: SetCustomModeBitmaps. Call before toolbar is actually created.
//   Feb-13-2005: More bloat?
// * More drop-down editors (for wxLongStringProperty etc.) instead of modal dialogs.
//   Problem: complex, multi-sub-control popups do not work yet (will they ever work?).
//
// Low Priority:
// * wxPropertyGridManager::SetFont.
// * Basic context menu with Reset() and checkable Show Description that toggle the help box.
// * wxCustomEnumProperty - Allows user to set the image as well.
// * GetItemAtY() to use binary search.
// * Preparations for wxPGProperty direct usage.
// * Refine dialog-position auto-generator.
// * Maybe different colour lines between categories (like light grey ones in .NET).
//   (though I don't think its that elegant).
// * wxGTK1: Multichoice can't get value correctly.
// * wxGTK1: Control(s) disapper after:
//     Splitter centering.
//     Collapse expand.
//     - Refresh is not enough?
//

//
// Documentation Todo:
// * Set/GetPropertyValue: Strings work for all value types.
// * SetPropertyAttribute.
// * Having graphics glitches? Use Freeze and Thaw - they have extended functionaly in PG.
