AppChooserDialog shows a AppChooserWidget inside a Dialog.
Note that AppChooserDialog does not have any interesting methods of its own. Instead, you should get the embedded AppChooserWidget using get_widget and call its methods if the generic AppChooser interface is not sufficient for your needs.
To set the heading that is shown above the AppChooserWidget, use set_heading.
Example: AppChooserDialog:
public class Application : Gtk.Window {
public Application () {
// Prepare Gtk.Window:
this.title = "My Gtk.AppChooserDialog";
this.window_position = Gtk.WindowPosition.CENTER;
this.destroy.connect (Gtk.main_quit);
// The button:
Gtk.AppChooserDialog dialog = new Gtk.AppChooserDialog.for_content_type (this, 0, "image/png");
if (dialog.run () == Gtk.ResponseType.OK) {
AppInfo info = dialog.get_app_info ();
if (info != null) {
print ("%s:\n", title);
print (" Name: %s\n", info.get_display_name ());
print (" Desc: %s\n", info.get_description ());
}
}
dialog.close ();
}
public static int main (string[] args) {
Gtk.init (ref args);
Application app = new Application ();
app.show_all ();
Gtk.main ();
return 0;
}
}
