On some platforms, such as GTK+, this event is simulated (simply generated just before the paint event) and may cause flicker. It is therefore recommended that you set the text background colour explicitly in order to prevent flicker. The default background colour under GTK+ is grey. To intercept this event, use the EVT_ERASE_BACKGROUND macro in an event table definition. You must call wxEraseEvent::GetDC and use the returned device context if it is non-NULL. If it is NULL, create your own temporary wxClientDC object. .SH REMARKS Use the device context returned by GetDC to draw on, don't create a wxPaintDC in the event handler. .SH "PARENTS" wxEvent wxObject .SH "INCLUDE FILES" wx/event.h .SH MEMBERS .SS wxEraseEvent (int id = 0wxDC* dc = NULL) Constructor. .SS wxDC* GetDC () Returns the device context associated with the erase event to draw on. .SH EVENTS .SS EVT_ERASE_BACKGROUND(func) Process a wxEVT_ERASE_BACKGROUND event. .SH "SEE ALSO" wxEvent wxObject Event handling overview .SH "AUTHORS" Documentation content by Julian Smart, Robert Roebling, Vadim Zeitlin, Robin Dunn, et al Conversion to manpage format by Arnout Engelen (http://bzzt.net), bugreports welcome.
