Gtk.AppChooserDialog
Description: Reference for Gtk.AppChooserDialog

### Class

# GtkAppChooserDialog

#### Description [src]

    final class Gtk.AppChooserDialog : Gtk.Dialog {
      /* No available fields */
    }

`GtkAppChooserDialog` shows a `GtkAppChooserWidget` inside a `GtkDialog`.

Note that `GtkAppChooserDialog` does not have any interesting methods of its own. Instead, you should get the embedded `GtkAppChooserWidget` using `gtk_app_chooser_dialog_get_widget()` and call its methods if the generic `GtkAppChooser` interface is not sufficient for your needs.

To set the heading that is shown above the `GtkAppChooserWidget`, use `gtk_app_chooser_dialog_set_heading()`.
