Struct gtk4::AboutDialog
source · #[repr(transparent)]pub struct AboutDialog { /* private fields */ }Expand description
The AboutDialog 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. AboutDialog
displays these as clickable links. By default, it calls FileLauncher::launch()
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.com>. To specify a website with a title,
use a string like GTK team https://www.gtk.org.
To make constructing a AboutDialog as convenient as possible, you can
use the function 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 AboutDialog,
as shown in the following example:
⚠️ The following code is in 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
AboutDialog has a single CSS node with the name window and style
class .aboutdialog.

authors
the authors of the application
sourcepub fn set_comments(&self, comments: Option<&str>)
pub fn set_comments(&self, comments: Option<&str>)
Sets the comments string to display in the about dialog.
This should be a short string of one or two lines.
comments
a comments string
sourcepub fn set_copyright(&self, copyright: Option<&str>)
pub fn set_copyright(&self, copyright: Option<&str>)
Sets the copyright string to display in the about dialog.

sourcepub fn set_license(&self, license: Option<&str>)
pub fn set_license(&self, license: Option<&str>)

If license is NULL, the license page is hidden.
license
the license information
sourcepub fn set_license_type(&self, license_type: License)
pub fn set_license_type(&self, license_type: License)

sourcepub fn set_system_information(&self, system_information: Option<&str>)
pub fn set_system_information(&self, system_information: Option<&str>)
Sets the system information to be displayed in the about dialog.

page is hidden.
See property::AboutDialog::system-information.
system_information
system information
sourcepub fn set_translator_credits(&self, translator_credits: Option<&str>)
pub fn set_translator_credits(&self, translator_credits: Option<&str>)
Sets the translator credits string which is displayed in the credits page.
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:
⚠️ The following code is in c ⚠️
GtkWidget *about = gtk_about_dialog_new ();
gtk_about_dialog_set_translator_credits (GTK_ABOUT_DIALOG (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 AboutDialog will detect if “translator-credits”
is untranslated and omit translator credits.
translator_credits
the translator credits
sourcepub fn set_version(&self, version: Option<&str>)
pub fn set_version(&self, version: Option<&str>)
sourcepub fn set_website(&self, website: Option<&str>)
