Using QuickTime SMIL Extensions

QuickTime takes advantage of SMIL's extensibility by adding tags that you can use to enhance a presentation. To make use of QuickTime extensions in your presentations, you have to add the special binding otherTagString in the WOSMILDocument element. Then you must bind it to an instance variable that provides the appropriate string.

  1. Select the WOSMILDocument element in your component.
  2. In the WOSMILDocument Binding Inspector window, add the otherTagString binding.
  3. Bind otherTagString to an instance variable of type String named qtNameSpace.
  4. In the component class's constructor, initialize qtNameSpace to "xmlns:qt=\"http://www.apple.com/quicktime/resources/smilextensions\"".

    QuickTime does not actually access the URL; it is used only to uniquely identify the QuickTime SMIL extensions. For more information, see http://www.apple.com/quicktime/authoring/qtsmil.html.
