CWinApp::DoWaitCursor

virtual void DoWaitCursor( int nCode );

Parameters

nCode

If this parameter is 1, a wait cursor appears. If 0, the wait cursor is restored without incrementing the reference count. If –1, the wait cursor ends.

Remarks

This member function is called by the framework to implement CWaitCursor, CCmdTarget::BeginWaitCursor, CCmdTarget::EndWaitCursor, and CCmdTarget::RestoreWaitCursor. The default implements an hourglass cursor. DoWaitCursor maintains a reference count. When positive, the hourglass cursor is displayed.

While you would not normally call DoWaitCursor directly, you could override this member function to change the wait cursor or to do additional processing while the wait cursor is displayed.

For an easier, more streamlined way to implement a wait cursor, use CWaitCursor.
