.SH NAME
wxEraseEvent \- Functions for wxEraseEvent class
.SH DESCRIPTION
.LP
An erase event is sent when a window\&'s background needs to be repainted\&.
.LP
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\&.
.LP
To intercept this event, use the EVT_ERASE_BACKGROUND macro in an event table definition\&.
.LP
You must use the device context returned by \fIgetDC/1\fR\& to draw on, don\&'t create a \fIwxPaintDC\fR\& in the event handler\&.
.LP
See: Overview events 
.LP
This class is derived (and can use functions) from: \fIwxEvent\fR\&

Use \fIwxEvtHandler:connect/3\fR\& with \fIwxEraseEventType\fR\& to subscribe to events of this type\&.
