CDockablePane::OnBeforeChangeParent
The framework calls this method before it changes the parent of the pane.
virtual void OnBeforeChangeParent(
CWnd* pWndNewParent,
BOOL bDelay = FALSE
);
Parameters
[in] pWndNewParent
A pointer to the new parent window.[in] bDelay
BOOL that specifies whether to delay recalculation of the docking layout if the pane is undocked. For more information, see CDockablePane::UndockPane.
Remarks
If the pane is docked and the new parent does not allow docking, this method undocks the pane.
If the pane is being converted to a tabbed document, this method stores its recent docking position. The framework uses the recent docking position to restore the position of the pane when it is converted back to a docked state.
