                SizeEvent

A size event holds information about size change events. The EVT_SIZE handler function will be called when the window it is bound to has been resized.

Note that the size passed is of the whole window: call wx.Window.GetClientSize 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 and that area is all that is in the update region for the next paint event. 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 wx.Window.Refresh to invalidate the entire window.
