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 dialog often contain links and email addresses. GtkAboutDialog
supports this by offering global hooks, which are called when the user
clicks on a link or email address, see gtk_about_dialog_set_email_hook()
and gtk_about_dialog_set_url_hook(). Email addresses in the
authors, documenters and artists properties are recognized by looking for
<user@host>, URLs are
recognized by looking for http://url, with
url extending to the next space, tab or line break.
Since 2.18 GtkAboutDialog provides default website and email hooks that
use gtk_show_uri().
If you want provide your own hooks overriding the default ones, it is important to do so before setting the website and email URL properties, like this:
1 2 |
gtk_about_dialog_set_url_hook (GTK_ABOUT_DIALOG (dialog), launch_url, NULL, NULL); gtk_about_dialog_set_website (GTK_ABOUT_DIALOG (dialog), app_url); |
To disable the default hooks, you can pass NULL as the hook func. Then,
the GtkAboutDialog widget will not display the website or the
email addresses as clickable.
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); |
Note that prior to GTK+ 2.12, the "program-name" property was called "name". This was changed to avoid the conflict with the "name" property.

Using gettext(), a simple way to achieve that is to mark the
string for translation:
1 |
gtk_about_dialog_set_translator_credits (about, _("translator-credits")); |
