LayoutAnchorable

A LayoutAnchorable is in AvalonDock an element that can be anchored into a flexible position (eg.: bottom, top, left, right of MainWindow). Such a flexibility is usually required for a Tool Window since users should be able to dock a tool window around their document.

A LayoutDocument (document) in turn, can also be docked in a (less) flexible manner but only inside one collection called DocumentsPane.
