wxEraseEvent - Functions for wxEraseEvent class

Data Types

wxEraseEvent() = wx:wx_object()

       wxErase() =
           #wxErase{type = wxEraseEvent:wxEraseEventType(),
                    dc = wxDC:wxDC()}

       wxEraseEventType() = erase_background

Description

       An erase event is sent when a window's background needs to be repainted.

       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  use  the  device context returned by getDC/1 to draw on, don't create a wxPaintDC in the event
       handler.

       See: Overview events

       This class is derived (and can use functions) from: wxEvent

       wxWidgets docs: wxEraseEvent

Events

       Use wxEvtHandler:connect/3 with wxEraseEventType to subscribe to events of this type.

Exports

getDC(This)->wxDC:wxDC()

              Types:

                 This = wxEraseEvent()

              Returns the device context associated with the erase event to draw on.

              The returned pointer is never NULL.
