A PanedWindow should be used to group components into Panes separated by Sashes and Separators for adjusting the relative size of each Pane. This component must be composed of any number of groups of components, called Panes, each separated by a Sash and a Separator. The Panes, Sashes, and Separators must be grouped linearly, either horizontally or vertically. A Sash must be composed of a handle on the Separator between two Panes for adjusting the position of the Separator, and therefore the size of the Panes next to it.
As a Sash is moved, the Pane in the direction of the Sash movement must get smaller and the other Pane must get larger by an equal amount. If a Pane is adjusted to its minimum size, adjustment should continue with the next Pane in the direction of the Sash movement.
This component must follow the navigation model described in Navigation.
For information about activating a Sash, see the reference page for Sash.
