Description

WMEraseBkgnd is the message handler for the WM_ERASEBKGND Windows message.

WMEraseBkgnd represents the message handler for the WM_ERASEBKGND Windows message. WMEraseBkgnd is a message method that is executed each time the operating system requests the background of the shadow window to be erased. WMEraseBkgnd prevents the message from going to the default handlers of TCustomControl. Thus, the background of the shadow window is not erased.
