CDockablePane: : IsResizable ()


By default, dockable panes are the resizable. To prevent resizing, override this method in a derived class and return FALSE. Note that a FALSE value leads To a failed ASSERT in CPane: : DockPane. Use CDockingManager: : AddPane home To dock a pane within a parent frame.

Panes that always be resized can neither complete nor enter auto - hide mode and are always located at the outer edge of the parent frame.
