wxWindow is the base class for all windows. Any children of the window will be deleted
automatically by the destructor before the window itself is deleted.
-Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
-help text. These must not be called by a user program and are documented only for illustration.
-On several platforms, only a few of these handlers are actually written (they are not always
-needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
-the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
-platform can implement its native behaviour or just ignore the event if nothing needs to be
-done.

Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
release the capture.
+Note that wxWindows maintains the stack of windows having captured the mouse
+and when the mouse is released the capture returns to the window which had had
+captured it previously and it is only really released if there were no previous
+window. In particular, this means that you must release the mouse as many times

-
-\wxheading{Parameters}
-
-\docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
-
-\wxheading{Remarks}
-
-Use the EVT\_PAINT macro in an event table definition to intercept paint events.
-
-Note that In a paint event handler, the application must {\it always} create a \helpref{wxPaintDC}{wxpaintdc} object,
-even if you do not use it. Otherwise, under MS Windows, refreshing for this and other windows will go wrong.
-
-For example:
-
-\small{%
-\begin{verbatim}
- void MyWindow::OnPaint(wxPaintEvent\& event)
- {
- wxPaintDC dc(this);
-
- DrawMyDocument(dc);
- }
-\end{verbatim}
-}%
-
-You can optimize painting by retrieving the rectangles
-that have been damaged and only repainting these. The rectangles are in
-terms of the client area, and are unscrolled, so you will need to do
-some calculations using the current view position to obtain logical,
-scrolled units.
-
-Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
-
-{\small%
-\begin{verbatim}
-// Called when window needs to be repainted.
-void MyWindow::OnPaint(wxPaintEvent\& event)
-{
- wxPaintDC dc(this);
-
- // Find Out where the window is scrolled to
- int vbX,vbY; // Top left corner of client
- GetViewStart(&vbX,&vbY);
-
- int vX,vY,vW,vH; // Dimensions of client area in pixels
- wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
-
- while (upd)
- {
- vX = upd.GetX();
- vY = upd.GetY();
- vW = upd.GetW();
- vH = upd.GetH();
-
- // Alternatively we can do this:
- // wxRect rect;
- // upd.GetRect(&rect);
-
- // Repaint this rectangle
- ...some code...
-
- upd ++ ;
- }

-
-When a window is resized, usually only a small part of the window is damaged and you
-may only need to repaint that area. However, if your drawing depends on the size of the window,
-you may need to clear the DC explicitly and repaint the whole window. In which case, you
