NAME

6       wxEraseEvent - Functions for wxEraseEvent class
7

DESCRIPTION

9       An  erase  event  is  sent  when  a window's background needs to be re‐
10       painted.
11
12       On some platforms, such as GTK+, this event is simulated (simply gener‐
13       ated  just  before the paint event) and may cause flicker. It is there‐
14       fore recommended that you set the text background colour explicitly  in
15       order  to  prevent flicker. The default background colour under GTK+ is
16       grey.
17
18       To intercept this event, use the EVT_ERASE_BACKGROUND macro in an event
19       table definition.
20
21       You  must  use the device context returned by getDC/1 to draw on, don't
22       create a wxPaintDC in the event handler.
