  49  * @Short_description: Application chooser widget that can be embedded in other widgets
  50  *
  51  * #GtkAppChooserWidget is a widget for selecting applications.
  52  * It is the main building block for #GtkAppChooserDialog. Most
  53  * applications only need to use the latter; but you can use
  54  * this widget as part of a larger widget if you have special needs.
  55  *
  56  * #GtkAppChooserWidget offers detailed control over what applications
  57  * are shown, using the
  58  * #GtkAppChooserWidget:show-default,
  59  * #GtkAppChooserWidget:show-recommended,
  60  * #GtkAppChooserWidget:show-fallback,
  61  * #GtkAppChooserWidget:show-other and
  62  * #GtkAppChooserWidget:show-all
  63  * properties. See the #GtkAppChooser documentation for more information
  64  * about these groups of applications.
  65  *
  66  * To keep track of the selected application, use the
  67  * #GtkAppChooserWidget::application-selected and #GtkAppChooserWidget::application-activated signals.
