Inheritance diagram for wx.EraseEvent:
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 wx.EVT_ERASE_BACKGROUND macro in an event table definition.
You must call GetDC and use the returned device context if it is not None. If it is None, create your own temporary wx.ClientDC object.
| Event Name | Description |
|---|---|
| wx.EVT_ERASE_BACKGROUND(func) | Process a wx.wxEVT_ERASE_BACKGROUND event. |
Use the device context returned by GetDC to draw on, don’t create a wx.PaintDC in the event handler.
