/**
* GtkAppChooserWidget:
*
* `GtkAppChooserWidget` is a widget for selecting applications.
*
* It is the main building block for [class@Gtk.AppChooserDialog].
* 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
* [property@Gtk.AppChooserWidget:show-default],
* [property@Gtk.AppChooserWidget:show-recommended],
* [property@Gtk.AppChooserWidget:show-fallback],
* [property@Gtk.AppChooserWidget:show-other] and
* [property@Gtk.AppChooserWidget:show-all] properties. See the
* [iface@Gtk.AppChooser] documentation for more information about these
* groups of applications.
*
* To keep track of the selected application, use the
* [signal@Gtk.AppChooserWidget::application-selected] and
* [signal@Gtk.AppChooserWidget::application-activated] signals.
*
* ## CSS nodes
*
* `GtkAppChooserWidget` has a single CSS node with name appchooser.
*
* Deprecated: 4.10: The application selection widgets should be
* implemented according to the design of each platform and/or
* application requiring them.
