/**
* SECTION:gtkappchooserwidget
* @Title: GtkAppChooserWidget
* @Short_description: Application chooser widget that can be embedded in other widgets
*
* #GtkAppChooserWidget is a widget for selecting applications.
* It is the main building block for #GtkAppChooserDialog. Most
* applications only need to use the latter; but you can use
* this widget as part of a larger widget if you have special needs.
*
* #GtkAppChooserWidget offers detailed control over what applications
* are shown, using the
* #GtkAppChooserWidget:show-default,
* #GtkAppChooserWidget:show-recommended,
* #GtkAppChooserWidget:show-fallback,
* #GtkAppChooserWidget:show-other and
* #GtkAppChooserWidget:show-all
* properties. See the #GtkAppChooser documentation for more information
* about these groups of applications.
*
* To keep track of the selected application, use the
* #GtkAppChooserWidget::application-selected and #GtkAppChooserWidget::application-activated signals.
*
* # CSS nodes
*
* GtkAppChooserWidget has a single CSS node with name appchooser.
