Class
GtkAboutDialog
Description [src]
final class Gtk.AboutDialog : Gtk.Window
implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget, Gtk.Native, Gtk.Root, Gtk.ShortcutManager {
/* No available fields */
}The GtkAboutDialog 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. GtkAboutDialog
displays these as clickable links. By default, it calls gtk_file_launcher_launch()
when a user clicks one. The behaviour can be overridden with the
GtkAboutDialog::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 GtkAboutDialog as convenient as possible, you can
use the function 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 GtkAboutDialog,
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
GtkAboutDialog has a single CSS node with the name window and style
class .aboutdialog.
