 A size event holds information about size change events.
 
+The EVT\_SIZE handler function will be called when the window has been resized.
+
+You may wish to use this for frames to resize their child windows as appropriate.
+
+Note that the size passed is of
+the whole window: call \helpref{wxWindow::GetClientSize}{wxwindowgetclientsize} for the area which may be
+used by the application.
+
+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
+may need to call \helpref{wxWindow::Refresh}{wxwindowrefresh} to invalidate the entire window.
