CMFCToolBarMenuButton::IsExclusive
Indicates whether the button is in exclusive mode.
virtual BOOL IsExclusive() const;
Return Value
TRUE if the button is working in exclusive mode; otherwise FALSE.
Remarks
When a user opens a popup menu for a button and then moves the mouse pointer over another toolbar or menu button, the popup menu closes unless the button is in exclusive mode.
The default implementation always returns FALSE. Override this method in a derived class if you want to turn on exclusive mode.
