/* Paned Widgets
|
|
*
|
|
* The HPaned and VPaned Widgets divide their content
|
|
* area into two panes with a divider in between that the
|
|
* user can adjust. A separate child is placed into each
|
|
* pane.
|
|
*
|
|
* There are a number of options that can be set for each pane.
|
|
* This test contains both a horizontal (HPaned) and a vertical
|
|
* (VPaned) widget, and allows you to adjust the options for
|
|
* each side of each widget.
