-INCOMPATIBLE CHANGES SINCE 2.4.x
-================================
-
- Please take a few minutes to read the following list, especially
- paying attention to the most important changes which are marked
- with '!' in the first column.
-
- Also please note that you should ensure that WXWIN_COMPATIBILITY_2_4
- is defined to 1 if you wish to retain maximal compatibility with 2.4
- series.
-
-! windows are no longer fully repainted when resized, use new style
- wxFULL_REPAINT_ON_RESIZE to force this (wxNO_FULL_REPAINT_ON_RESIZE still
- exists but doesn't do anything any more, this behaviour is default now)
-
-! wxWindow::m_font and m_backgroundColour/m_foregroundColour are no longer
- always set, use GetFont(), GetBack/ForegroundColour() to access
- them, and they will be dynamically determined if necessary.
-
-
-! The Sizers have had some fundamental internal changes in the 2.5.2
- and 2.5.3 releases intended to make them do more of the "Right
- Thing" but also be as backwards compatible as possible. First a bit
- about how things used to work:
-
- * The size that a window had when Add()ed to the sizer was assumed
- to be its minimal size, and that size would always be used by
- default when calculating layout size and positions, and the
- sizer itself would keep track of that minimal size.
-
- * If the window item was Add()ed with the wxADJUST_MINSIZE flag
- then when layout was calculated the item's GetBestSize would be
- used to reset the minimal size that the sizer used.
-
- The main thrust of the new Sizer changes was to make behaviour like
- wxADJUST_MINSIZE be the default, and also to push the tracking of
- the minimal size to the window itself (since it knows its own needs)
- instead of having the sizer take care of it. Consequently these
- changes were made:
-
- * The wxFIXED_MINSIZE flag was added to allow for the old
- behaviour. When this flag is used the size a window has when
- Add()ed to the sizer will be treated as its minimal size and it
- will not be readjusted on each layout.
-
- * The min size stored in wxWindow and settable with SetSizeHints or
- SetMinSize will by default be used by the sizer (if it was set)
- as the minimal size of the sizer item. If the minsize was not
- set (or was only partially set) then the window's best size is
- fetched and it is used instead of (or blended with) the minsize.
- wxWindow:GetBestFittingSize was added to facilitate getting the
- size to be used by the sizers.
-
- * The best size of a window is cached so it doesn't need to
- recaculated on every layout. wxWindow::InvalidateBestSize was
- added and should be called (usually just internally in control
- methods) whenever something is done that would make the best
- size change.
-
- * All wxControls were changed to set the minsize to what is passed
- to the constructor or Create method, and also to set the real
- size of the control to the blending of the minsize and bestsize.
- wxWindow::SetBestFittingSize was added to help with this,
- although most controls don't need to call it directly because it
- is called indirectly via the SetInitialSize called in the base
- classes.
-
- At this time, the only situation known not to work the same as
- before is the following:
-
- win = new SomeWidget(parent);
- win->SetSize(SomeNonDefaultSize);
- sizer->Add(win);
-
- In this case the old code would have used the new size as the
- minimum, but now the sizer will use the default size as the minimum
- rather than the size set later. It is an easy fix though, just move
- the specification of the size to the constructor (assuming that
- SomeWidget will set its minsize there like the rest of the controls
- do) or call SetMinSize instead of SetSize.
-
- In order to fit well with this new scheme of things, all wxControls
- or custom controls should do the following things. (Depending on
- how they are used you may also want to do the same thing for
- non-control custom windows.)
-
- * Either override or inherit a meaningful DoGetBestSize method
- that calculates whatever size is "best" for the control. Once
- that size is calculated then there should normally be a call to
- CacheBestSize to save it for later use, unless for some reason
- you want the best size to be recalculated on every layout.
-
- * Any method that changes the attributes of the control such that
- the best size will change should call InvalidateBestSize so it
- will be recalculated the next time it is needed.
-
- * The control's constructor and/or Create method should ensure
- that the minsize is set to the size passed in, and that the
- control is sized to a blending of the min size and best size.
- This can be done by calling SetBestFittingSize.
-
-
-
-- no initialization/cleanup can be done in wxApp/~wxApp because they are
- now called much earlier/later than before; please move any exiting code
- from there to wxApp::OnInit()/OnExit()
-- also, OnExit() is not called if OnInit() fails
-- finally the program exit code is OnRun() return value, not OnExit() one
-- wxTheApp can't be assigned to any longer, use wxApp::SetInstance() instead
-- wxFileType::GetIcon() returns wxIconLocation, not wxIcon
-- wxColourDatabase is not a wxList any more, use AddColour to add new colours
-- wxWindow::Clear() is now called ClearBackground()
-- pointer returned by wxFont::GetNativeFontInfo() must not be deleted now
-- wxMouseEvent::Moving() doesn't return true if mouse is being dragged any more
-- (most) controls now inherit parents colours by default, override
- ShouldInheritColours() to return false if you don't want this to happen
-- wxApp::SendIdleEvent() now takes 2 arguments
-- wxTabView::GetLayers() changed return type from wxList& to wxTabLayerList&
- (when WXWIN_COMPATIBILITY_2_4 == 0)
-- wxID_SEPARATOR (id used for the menu separators) value changed from -1 to -2
-- wxGetNumberFromUser() is now in separate wx/numdlg.h, not wx/textdlg.h
-- wxChoice and wxCombobox now handle their size in the same way as in all the
- other ports under MSW, new code is actually correct but different from weird
- stuff they were doing before so the behaviour of your programs might change
-- wxTaskBarIcon objects must now be destroyed before the application can exit.
- Previously, the application terminated if there were no top level windows;
- now it terminates if there are no top level windows or taskbar icons left.
-- wxZlibInputStream is not by default compatible with the output of the
- 2.4.x version of wxZlibOutputStream. However, there is a compatibilty mode,
- switched on by passing wxZLIB_24COMPATIBLE to the constructor.
-- when WXWIN_COMPATIBILITY_2_4 == 0 wxHashTable uses a new implementation
- not using wxList keyed interface (the same used when wxUSE_STL == 1),
- the only incompatibility being that Next() returns a wxHashTable::Node*
- instead of a wxNode*.
-- non-const wxDC methods GetBackground(), GetBrush(), GetFont() and GetPen()
- as well as wxWindow methods GetFont() and GetCursor() don't exist any more,
- please fix your code -- it never worked correctly anyhow if you modified the
- objects returned by these methods so you should simply switch to using const
- methods.
-- wxWindow::GetFont() now returns wxFont object instead of reference
-- EVT_XXX macros are now type-safe; code that uses wrong type for event
- handler's argument will no longer compile.
-- Identical functionality of wxFileDialog::ParseWildcard,
- wxGenericDirCtrl::ParseFilter, Motif and MSW parsing native dialogs
- is now accessible in ::wxParseCommonDialogsFilter
-- wxNotebookSizer and wxBookCtrlSizer are now deprecated -- they are no longer
- needed, you can treat wxNotebook as any other control and put it directly
- into the sizer that was wxNotebookSizer's parent sizer in old code.
-- wxFile methods now return either wxFileOffset or wxFileSize_t which may be a
- 64 bit integer type, even on 32 bit platforms, instead of off_t and so the
- return value of wxFile::Length(), for example, shouldn't be assigned to off_t
- variable any more (the compiler might warn you about this)
-- wxListItem::m_data is now of type wxUIntPtr, not long, for compatibility
- with 64 bit systems
-
-
-DEPRECATED METHODS SINCE 2.4.x
-==============================
-
-Deprecated methods may still be used but will disappear in future wxWidgets
-versions, please update your code to not use them.
-
-- wxDocManager::GetNoHistoryFiles() renamed to GetHistoryFilesCount()
-- wxSizer::Remove(wxWindow *), use Detach() instead [it is more clear]
-- wxSizer::Set/GetOption(): use Set/GetProportion() instead
-- wxKeyEvent::KeyCode(): use GetKeyCode instead
-- wxList::Number, First, Last, Nth: use GetCount, GetFirst/Last, Item instead
-- wxNode::Next, Previous, Data: use GetNext, GetPrevious, GetData instead
-- wxListBase::operator wxList&(): use typesafe lists instead
-- wxTheFontMapper: use wxFontMapper::Get() instead
-- wxStringHashTable: use wxHashMap instead
-- wxHashTableLong: use wxHashMap instead
-- wxArrayString::GetStringArray: use wxCArrayString or alternative wxWidgets
- methods taking wxArrayString
-- wxArrayString::Remove(index, count): use RemoveAt instead
-- wxTreeItemId conversion to long is deprecated and shouldn't be used
-- wxTreeCtrl::GetFirst/NextChild() 2nd argument now has type wxTreeItemIdValue
- and not long, please change declarations of "cookie"s in your code
- accordingly -- otherwise your code won't work on 64 bit platforms
-- [MSW only] wxWindow::GetUseCtl3D(), GetTransparentBackground() and
- SetTransparent() as well as wxNO_3D and wxUSER_COLOURS styles
-- wxList keyed interface: use wxHashMap instead
-- wxColourDatabase::FindColour(): use Find() instead (NB: different ret type)
-- wxHashTable::Next: use wxHashTable::Node* or
- wxHashTable::compatibility_iterator to store the return
- value
-- wxWave class; use wxSound instead
-- The wxHIDE_READONLY flag for wxFileDialog was not implemented
- and has now been removed
-- wxTaskBarIcon::OnXXX() virtual methods: use events instead
-- obsolete and not used wxUSE_GENERIC_DIALOGS_IN_MSW has been removed
-- wxDbTable::wxDbTable with wxChar* deprecated, same with wxString& instead

+ printing stuff in the GTK port.
+- Added support to the wxODBC classes for Firebird 1.5 database
+- The samples\db sample program now includes an optional example of using a BLOB
+ datatype (if BLOB support is enabled and supported by the database)

+ after wxTextCtrl creation if you really need to. (Mart Raudsepp)
+- Changed calls to GTK+ 2.4.x functions so that the code checks at
+ runtime, which library version is installed so that these functions
+ are only called with GTK+ 2.4.x installed and should yield linker
