Called by the framework to show or hide panes.
- [in] bShow
TRUE to show panes, FALSE to hide panes.
TRUE if the state of the panes changes as a result of calling this method, FALSE if the panes are already in the state specified by bShow. For example, if the panes are hidden and bShow is FALSE, the return value is FALSE.
The default implementation removes the toolbar from the top-level frame window.
If CDockingManager::m_bHideDockingBarsInContainerMode is TRUE (the default), all docking panes will be hidden.
