AboutDialog

open class AboutDialog : Window, AboutDialogProtocol

The GtkAboutDialog 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.

An example GtkAboutDialog

About dialogs often contain links and email addresses. GtkAboutDialog displays these as clickable links. By default, it calls [funcGtk.show_uri] when a user clicks one. The behaviour can be overridden with the [signalGtk.AboutDialog::activate-link] signal.

To specify a person with an email address, use a string like Edgar Allan Poe <edgarpoe.com>. 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 [funcGtk.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:

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.

The AboutDialog type acts as a reference-counted owner of an underlying GtkAboutDialog instance. It provides the methods that can operate on this data type through AboutDialogProtocol conformance. Use AboutDialog as a strong reference or owner of a GtkAboutDialog instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the AboutDialog instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkAboutDialog>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the AboutDialog instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkAboutDialog>)

    Parameters

    op

    pointer to the underlying object
