CMFCToolBarButton::IsEditable
Determines whether the button can be customized.
virtual BOOL IsEditable() const;
Return Value
Nonzero if a button can be customized by the user; otherwise 0.
Remarks
The framework calls this method to determine whether the user can customize the toolbar button by using drag-and-drop or edit operations.
The default implementation returns FALSE if the command ID of the button is a standard command (you can determine this by calling the IsStandardCommand function) or if the command ID is in the list of protected commands. For more information about protected commands, see CMFCToolBarButton::GetProtectedCommands and CMFCToolBarButton::SetProtectedCommands.
Override this method to customize its behavior.
