Provides a default message loop for user-interface threads.

virtual int Run( );

Return Value

An int value that is returned by the thread. This value can be retrieved by calling GetExitCodeThread.


Run acquires and dispatches Windows messages until the application receives a WM_QUIT message. If the thread's message queue currently contains no messages, Run calls OnIdle to perform idle-time processing. Incoming messages go to the PreTranslateMessage member function for special processing and then to the Windows function TranslateMessage for standard keyboard translation. Finally, the DispatchMessage Windows function is called.

Run is rarely overridden, but you can override it to implement special behavior.

This member function is used only in user-interface threads.
