Called by the framework just before the pane changes its parent window.
virtual void OnBeforeChangeParent(
CWnd* pWndNewParent,
BOOL bDelay=FALSE
);
Parameters
[in] pWndNewParent
A pointer to a new parent window.[in] bDelay
Specifies whether layout adjustments must be delayed.
Remarks
The framework calls this method just before the pane's parent changes, usually because of a docking, floating, or auto-hide operation.
The default implementation does nothing.
