wxWindows 2.5/2.6 Change Log
----------------------------

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 stll
  exists but doesn't do anything any more, this behaviour is default now)


- 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.

wxTaskBarIcon must be explicitly destroyed now, otherwise the application
  won't exit even though there are no top level windows


DEPRECATED METHODS SINCE 2.4.x
==============================

Deprecated methods may still be used but will disappear in future wxWindows
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 wxWindows
                                 methods taking wxArrayString
- wxArrayString::Remove(index, count): use RemoveAt instead
- wxTreeItemId conversion to long is deprecated and shouldn't be used
- [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


OTHER CHANGES
=============

2.5.2
-----

All:

All (GUI):

- wxHtmlWindow now delays image scaling until rendering,
  resulting in much better display of scaled images
- Added UpdateSize to wxSplitterWindow to allow layout while hidden
- implemented Freeze/Thaw() for wxGenericTreeCtrl (Kevin Hock)

wxMSW:

- wxWindow::Freeze()/Thaw() can now be nested
- Added wxSP_NO_XP_THEME style to wxSplitterWindow to switch off
  XP theming (some applications look bad without 3D borders)
- wxMenuBar::GetLabelTop() doesn't include '&'s in the label any more
- wxRegConf couldn't read global settings without admin privileges and didn't
  even try to do it by default -- now it does
- wxTaskBarIcon must be explicitly destroyed now, otherwise the application
  won't exit even though there are no top level windows

wxMotif:

- removed wxMenuItem::DeleteSubMenu()
