Struct libadwaita::AboutWindow

source ·

pub struct AboutWindow { /* private fields */ }

👎Deprecated: Since 1.6

Available on crate feature v1_2 only.

Expand description

Use AboutDialog. A window showing information about the application.

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

§Main page

AboutWindow 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

AboutWindow 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 ()
Ordered list (<ol>), with list items (<li>)
Unordered list (<ul>), with list items (<li>)

Within paragraphs and list items, emphasis () 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][struct@crate::Gtk::AboutDialog#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

AboutWindow 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.

AboutWindow 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.

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 AboutWindow as convenient as possible, you can use the function show_about_window() which constructs and shows a window.

⚠️ The following code is in c ⚠️

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

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

  adw_show_about_window (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,
                         "developers", developers,
                         "designers", designers,
                         "translator-credits", _("translator-credits"),

§Signals

§`activate-link`

Emitted when a URL is activated.

Applications may connect to it to override the default behavior, which is to call show_uri().

Window

§`activate-default`

Emitted when the user activates the default widget of @window.

This is a keybinding signal.

The keybindings for this signal are all forms of the Enter key.

Action

§`activate-focus`

Emitted when the user activates the currently focused widget of @window.

This is a keybinding signal.

The default binding for this signal is ␣.

Action

§`close-request`

Emitted when the user clicks on the close button of the window.

§`enable-debugging`

Emitted when the user enables or disables interactive debugging.

When @toggle is true, interactive debugging is toggled on or off, when it is false, the debugger will be pointed at the widget under the pointer.

This is a keybinding signal.

The default bindings for this signal are Ctrl+Shift+I and Ctrl+Shift+D.

Action

§`keys-changed`

emitted when the set of accelerators or mnemonics that are associated with @window changes.

Widget

§`destroy`

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

§`direction-changed`

Emitted when the text direction of a widget changes.

§`hide`

Emitted when @widget is hidden.

§`keynav-failed`

Emitted if keyboard navigation fails.

See [WidgetExtManual::keynav_failed()][crate::gtk::prelude::WidgetExtManual::keynav_failed()] for details.

§`map`

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

§`mnemonic-activate`

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

§`move-focus`

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

§`query-tooltip`

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering “above” @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

§`realize`

Emitted when @widget is associated with a GdkSurface.

This means that [WidgetExtManual::realize()][crate::gtk::prelude::WidgetExtManual::realize()] has been called or the widget has been mapped (that is, it is going to be drawn).

§`show`

Emitted when @widget is shown.

§`state-flags-changed`

Emitted when the widget state changes.

See [WidgetExtManual::state_flags()][crate::gtk::prelude::WidgetExtManual::state_flags()].

§`unmap`

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

§`unrealize`

Emitted when the GdkSurface associated with @widget is destroyed.

This means that [WidgetExtManual::unrealize()][crate::gtk::prelude::WidgetExtManual::unrealize()] has been called or the widget has been unmapped (that is, it is going to be hidden).
