# AboutData

If a [script add-in](../../../scripting/script_add-ins) provides an [**OnAboutScript**](../scripting_events/onaboutscript) method, it is passed an **AboutData** object when invoked via the user clicking the _About_ button in Preferences.

| window        | _int_       | This is a handle to the parent window that the script should use if displaying a dialog via the [**Dialog**](dialog) object. Even though this is not a [**Lister**](lister) or [**Tab**](tab), it can still be assigned to the **Dialog.window** property to set the parent window of the dialog. |
