An about dialog is typically * opened when the user selects the `About` option from the `Help` menu. * All parts of the dialog are optional. * * ![An example GtkAboutDialog](aboutdialog.png) * * About dialogs often contain links and email addresses. `GtkAboutDialog` * displays these as clickable links. By default, it calls [func@Gtk.show_uri] * 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 `. 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 [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 `GtkAboutDialog`, * as shown in the following example: * * ```c * 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`. */ typedef struct { const char *name; const char *url; } LicenseInfo; /* LicenseInfo for each GtkLicense type;
