The GtkAboutDialog offers a simple way to display information about
a program like its 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_show_uri_on_window()
when a user clicks one. The behaviour can be overridden with the
“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 http://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:
1 2 3 4 5 |
gtk_show_about_dialog (NULL, "program-name", "ExampleCode", "logo", example_logo, "title" _("About ExampleCode"), NULL); |
It is also possible to show a GtkAboutDialog like any other GtkDialog,
e.g. using gtk_dialog_run()
. In this case, you might need to know that
the “Close” button returns the GTK_RESPONSE_CANCEL response id.

void gtk_about_dialog_set_translator_credits (GtkAboutDialog *about
,const gchar *translator_credits
);
Sets the translator credits string which is displayed in the translators tab of the secondary credits dialog.
The intended use for this string is to display the translator
of the language which is currently used in the user interface.
Using gettext()
, a simple way to achieve that is to mark the
string for translation:
1 2 |
gtk_about_dialog_set_translator_credits (about, _("translator-credits")); |
It is a good idea to use the customary msgid “translator-credits” for this purpose, since translators will already know the purpose of that msgid, and since GtkAboutDialog will detect if “translator-credits” is untranslated and hide the tab.
