/* Paned Widgets
|
|
*
|
|
* The GtkPaned Widget divides its content area into two panes
|
|
* with a divider in between that the user can adjust. A separate
|
|
* child is placed into each pane. GtkPaned widgets can be split
|
|
* horizontally or vertially.
|
|
*
|
|
* There are a number of options that can be set for each pane.
|
|
* This test contains both a horizontal and a vertical GtkPaned
|
|
* widget, and allows you to adjust the options for each side of
|
|
* each widget.
