Struct gtk::AboutDialog [−][src]
pub struct AboutDialog(_);
Expand description
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 show_uri_on_window()
when a user clicks one. The behaviour can be overridden with the
signal::AboutDialog::activate-link
signal.
To specify a person with an email address, use a string like “Edgar Allan Poe <edgar`poe`>”. 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:
⚠️ The following code is in C ⚠️
GdkPixbuf *example_logo = gdk_pixbuf_new_from_file ("./logo.png", NULL);
gtk_show_about_dialog (NULL,
"program-name", "ExampleCode",
"logo", example_logo,
"title", _("About ExampleCode"),
NULL);
It is also possible to show a AboutDialog
like any other Dialog
,
e.g. using DialogExt::run()
. In this case, you might need to know that
the “Close” button returns the ResponseType::Cancel
response id.
