Description

Provides message handling for all messages that do not have specific handlers.

Override DefaultHandler to extend the default handling of messages. DefaultHandler is the final opportunity for component writers to handle messages to controls. The method referenced by WindowProc provides the first opportunity. Individual message methods such as Click provide additional opportunities.

DefaultHandler handles the messages Windows sends to manage the control's text: WM_GETTEXT, WM_SETTEXT, and WM_GETTEXTLENGTH.
