### Class

# Gtk AppChooserWidget

#### Description [src]

    final class Gtk.AppChooserWidget : Gtk.Widget {
      /* No available fields */
    }

`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.
