|
|
* @Short_description: Represents an application mode in a GtkShortcutsWindow
|
|
*
|
|
* A GtkShortcutsSection collects all the keyboard shortcuts and gestures
|
|
* for a major application mode. If your application needs multiple sections,
|
|
* you should give each section a unique #GtkShortcutsSection:section-name and
|
|
* a #GtkShortcutsSection:title that can be shown in the section selector of
|
|
* the GtkShortcutsWindow.
|
|
*
|
|
* The #GtkShortcutsSection:max-height property can be used to influence how
|
|
* the groups in the section are distributed over pages and columns.
|
|
*
|
|
* This widget is only meant to be used with #GtkShortcutsWindow.
