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 - recalculated 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.
