Gtk.Dialog This class extends , providing a dialog to show information about a program.

The 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. supports this by offering global hooks, which are called when the user clicks on a link or email address, see and . Email addresses in the authors, documenters and artists properties are recognized by looking for <user@host>, URLs are recognized by looking for http://url, with url extending to the next space, tab or line break.

The following example creates and shows a from both assembly attributes and stored values.

  A object containing the native GLib type for the new instance.
  Constructs and initializes a new instance of for a specified native GLib type.
  Chain to this constructor if you have manually registered a native value for your subclass.
- Constructor
  2.12.0.0
  A pointing to the raw object to be managed by the new instance.
  Constructs and initializes a new instance of using an existing unmanaged object as its base.
  This is not typically used by managed code. It is primarily used for enclosing an existing object, created by unmanaged code, in a managed wrapper.

- Property
  2.12.0.0
  GLib.GType Gets the GLib type of the current instance. A value representing the native GLib type of . The value is used internally by the GLib type management system.
- Property
  2.12.0.0
  GLib.Property("license")
  System.String Gets and sets the license text of the program. A object containing the license text to display with the current instance. This string is displayed in a text view in a secondary dialog, therefore it is fine to use a long multi-paragraph text.
