/**
 * #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.
