Managing Your Panel's Settings
Sequence grabber components store their configuration information in Movie Toolbox user data items (see the chapter "Movie Toolbox" in Inside Macintosh: QuickTime for more information about user data items). This configuration information includes settings for each of the channels used by the sequence grabber. Because your panel component configures sequence grabber channels, your panel component is responsible for creating and formatting the contents of its user data items. The sequence grabber component calls your component whenever it wants to retrieve these settings. The sequence grabber may also use previously stored settings to restore your panel's settings. This section discusses the functions that allow the sequence grabber to work with your panel's settings.
The sequence grabber calls your SGPanelGetSettings function in order to retrieve your panel's current settings. The sequence grabber uses your SGPanelSetSettings function to restore those settings to some previous values.
