GtkAboutDialog

The gtk.about_dialog.AboutDialog offers a simple way to display information about a program.

The shown information includes the programs' logo, name, copyright, website and license. It is also possible to give credits to the authors, documenters, translators and artists who have worked on the program.

An about dialog is typically opened when the user selects the About option from the Help menu. All parts of the dialog are optional.

About dialogs often contain links and email addresses. gtk.about_dialog.AboutDialog displays these as clickable links. By default, it calls gtk.file_launcher.FileLauncher.launch when a user clicks one. The behaviour can be overridden with the signal@Gtk.AboutDialog::activate-link signal.

To specify a person with an email address, use a string like Edgar Allan Poe <edgar@poe.com>. To specify a website with a title, use a string like GTK team https://www.gtk.org.

To make constructing a gtk.about_dialog.AboutDialog as convenient as possible, you can use the function func@Gtk.show_about_dialog which constructs and shows a dialog and keeps it around so that it can be shown again.

Note that GTK sets a default title of _("About s") on the dialog window (where `s` is replaced by the name of the application, but in order to ensure proper translation of the title, applications should set the title property explicitly when constructing a gtk.about_dialog.AboutDialog, as shown in the following example:

GFile *logo_file = g_file_new_for_path ("./logo.png");
GdkTexture *example_logo = gdk_texture_new_from_file (logo_file, NULL);
g_object_unref (logo_file);

gtk_show_about_dialog (NULL,
                       "program-name", "ExampleCode",
                       "logo", example_logo,
                       "title", _("About ExampleCode"),
                       NULL);

CSS nodes

gtk.about_dialog.AboutDialog has a single CSS node with the name window and style class .aboutdialog.
