This method provides a simple way to set a background bitmap without defining an EVT_ERASE_BACKGROUND handler and, more importantly, one that works correctly in wxMSW for a window with children as it paints the background of transparent children too. Add a test of this method to the erase sample. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@67253 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
