## Detailed Description

Interface implemented by widgets for choosing an application.

This interface can be implemented by widgets which allow the user to choose an application (typically for the purpose of opening a file). The main objects that implement this interface are AppChooserWidget, AppChooserDialog and AppChooserButton.

Applications are represented by Gio::AppInfo objects here. GIO has a concept of recommended and fallback applications for a given content type. Recommended applications are those that claim to handle the content type itself, while fallback also includes applications that handle a more generic content type. GIO also knows the default and last-used application for a given content type. The AppChooserWidget provides detailed control over whether the shown list of applications should include default, recommended or fallback applications.

To obtain the application that has been selected in an AppChooser, use get_app_info().

See Platform-specific content typing in glibmm for more information about content types.

Since gtkmm 3.0:

## Member Function Documentation

static void Gtk::AppChooser::add_interface | ( | GType | gtype_implementer | ) |
| static

Glib::RefPtr<Gio::AppInfo> Gtk::AppChooser::get_app_info | ( |  | ) |

Returns the currently selected application.

Since gtkmm 3.0:

Returns
  A AppInfo for the currently selected application, or `nullptr` if none is selected. Free with Glib::object_unref().

Glib::RefPtr<const Gio::AppInfo> Gtk::AppChooser::get_app_info | ( |  | ) | const

Returns the currently selected application.

Since gtkmm 3.0:

Returns
  A AppInfo for the currently selected application, or `nullptr` if none is selected. Free with Glib::object_unref().

Glib::ustring Gtk::AppChooser::get_content_type | ( |  | ) | const

Returns the current value of the Gtk::AppChooser::property_content_type() property.

Since gtkmm 3.0:

Returns
  The content type of self. Free with Glib::free().

static GType Gtk::AppChooser::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

GtkAppChooser* Gtk::AppChooser::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GtkAppChooser* Gtk::AppChooser::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

AppChooser& Gtk::AppChooser::operator= | ( | AppChooser&& | src | ) |
| noexcept

Glib::PropertyProxy_ReadOnly< Glib::ustring > Gtk::AppChooser::property_content_type | ( |  | ) | const

The content type of the Gtk::AppChooser object.

See [GContentType][gio-GContentType] for more information about content types.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

void Gtk::AppChooser::refresh | ( |  | ) |

Reloads the list of applications.

Since gtkmm 3.0:

## Friends And Related Function Documentation

Glib::RefPtr< Gtk::AppChooser > wrap | ( | GtkAppChooser * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
