-\subsection{Incompatable changes since 2.4.x}\label{incompatiblesince24}
+\helpref{wxEvent}{wxevent} and its \helpref{derivatives}{eventhandlingoverview} do not have their public variable members public anymore.

-Windows are no longer fully repainted when resized, use new style \windowstyle{wxFULL\_REPAINT\_ON\_RESIZE} to force this (\windowstyle{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 \helpref{GetFont()}{wxwindowgetfont}, \helpref{GetBack}{wxwindowgetbackgroundcolour}/\helpref{ForegroundColour()}{wxwindowgetforegroundcolour} to access them, and they will be dynamically determined if necessary.

-\subsubsection{Sizers Internal Overhaul}\label{sizersinternaloverhaul}
+\wxheading{Sizers Internal Overhaul}
\helpref{The Sizers}{sizeroverview} 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:
size of the control to the blending of the minsize and bestsize.
\helpref{wxWindow::SetBestFittingSize}{wxwindowsetbestfittingsize} 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

+\item Either override or inherit a meaningful \helpref{DoGetBestSize}{wxwindowdogetbestsize} method
that calculates whatever size is "best" for the control. Once
that size is calculated then there should normally be a call to

+ \helpref{CacheBestSize}{wxwindowcachebestsize} to save it for later use, unless for some reason
you want the best size to be recalculated on every layout.
\item Any method that changes the attributes of the control such that
- the best size will change should call InvalidateBestSize so it
+ the best size will change should call \helpref{InvalidateBestSize}{wxwindowinvalidatebestsize} so it
will be recalculated the next time it is needed.
\item 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.

- wxID\_SEPARATOR (id used for the menu separators) value changed from -1 to -2
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;

variable any more (the compiler might warn you about this)
- wxListItem::m\_data is now of type wxUIntPtr, not long, for compatibility
- wxSizer::Add/Insert returns pointer to wxSizerItem just added so conditions
writeen with if(Add(..)==true) will not work. Use if(Add(..)) instead.
