## Implemented Interfaces

GtkAppChooserWidget implements AtkImplementorIface, GtkBuildable, GtkOrientable and GtkAppChooser.

## Includes

    #include <gtk/gtk.h>

## Description

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 “show-default”, “show-recommended”, “show-fallback”, “show-other” and “show-all” properties. See the GtkAppChooser documentation for more information about these groups of applications.

To keep track of the selected application, use the “application-selected” and “application-activated” signals.
