AboutDialog

Added in version 1.5.

class AboutDialog(**properties: Any)

Superclasses: Dialog, Widget, InitiallyUnowned, Object

Implemented Interfaces: Accessible, Buildable, ConstraintTarget

A dialog showing information about the application.

an about dialog is typically opened when the user activates the About … item in the application’s primary menu. All parts of the dialog are optional.

Main page

AdwAboutDialog prominently displays the application’s icon, name, developer name and version. They can be set with the application_icon, application_name, developer_name and version respectively.

What’s New

AdwAboutDialog provides a way for applications to display their release notes, set with the release_notes property.

Release notes are formatted the same way as AppStream descriptions.

The supported formatting options are:

• Paragraph (<p>)

• Ordered list (<ol>), with list items (<li>)

• Unordered list (<ul>), with list items (<li>)

Within paragraphs and list items, emphasis (<em>) and inline code (<code>) text styles are supported. The emphasis is rendered in italic, while inline code is shown in a monospaced font.

Any text outside paragraphs or list items is ignored.

Nested lists are not supported.

Only one version can be shown at a time. By default, the displayed version number matches version. Use release_notes_version to override it.

Details

The Details page displays the application comments and links.

The comments can be set with the comments property. Unlike comments, this string can be long and detailed. It can also contain links and Pango markup.

To set the application website, use website. To add extra links below the website, use add_link.

If the Details page doesn’t have any other content besides website, the website will be displayed on the main page instead.

Troubleshooting

AdwAboutDialog displays the following two links on the main page:

• Support Questions, set with the support_url property,

• Report an Issue, set with the issue_url property.

Additionally, applications can provide debugging information. It will be shown separately on the Troubleshooting page. Use the debug_info property to specify it.

It’s intended to be attached to issue reports when reporting issues against the application. As such, it cannot contain markup or links.

AdwAboutDialog provides a quick way to save debug information to a file. When saving, debug_info_filename would be used as the suggested filename.

Credits and Acknowledgements

The Credits page has the following default sections:

• Developers, set with the developers property,

• Designers, set with the designers property,

• Artists, set with the artists property,

• Documenters, set with the documenters property,

• Translators, set with the translator_credits property.

When setting translator credits, use the strings "translator-credits" or "translator_credits" and mark them as translatable.

The default sections that don’t contain any names won’t be displayed.

The Credits page can also contain an arbitrary number of extra sections below the default ones. Use add_credit_section to add them.

The Acknowledgements page can be used to acknowledge additional people and organizations for their non-development contributions. Use add_acknowledgement_section to add sections to it. For example, it can be used to list backers in a crowdfunded project or to give special thanks.

Each of the people or organizations can have an email address or a website specified. To add a email address, use a string like Edgar Allan Poe <edgar@poe.com>. To specify a website with a title, use a string like The GNOME Project https://www.gnome.org:

Legal

The Legal page displays the copyright and licensing information for the application and other modules.

The copyright string is set with the copyright property and should be a short string of one or two lines, for example: © 2022 Example.

Licensing information can be quickly set from a list of known licenses with the license_type property. If the application’s license is not in the list, license can be used instead.

To add information about other modules, such as application dependencies or data, use add_legal_section.

Constructing

To make constructing an AdwAboutDialog as convenient as possible, you can use the function show_about_dialog which constructs and shows a dialog.

static void
show_about (GtkApplication *app)
{
  const char *developers[] = {
    "Angela Avery",
    NULL
  };

  const char *designers[] = {
    "GNOME Design Team",
    NULL
  };

  adw_show_about_dialog (GTK_WIDGET (gtk_application_get_active_window (app)),
                         "application-name", _("Example"),
                         "application-icon", "org.example.App",
                         "version", "1.2.3",
                         "copyright", "© 2022 Angela Avery",
                         "issue-url", "https://gitlab.gnome.org/example/example/-/issues/",
                         "license-type", GTK_LICENSE_GPL_3_0,
