Inside Macintosh: QuickTime Components
This chapter discusses sequence grabber panel components. Sequence grabber components create a settings dialog box that includes items that are managed by sequence grabber panel components and sequence grabber channel components. Sequence grabber panel components allow sequence grabber components to obtain configuration information from the user for a particular sequence grabber channel component. Applications never call sequence grabber panel components directly; application developers use panel components only by calling the sequence grabber component.
This chapter addresses developers of sequence grabber panel components. If you plan to create a sequence grabber panel component, you should read the entire chapter. If you are writing an application that uses components of this type, you do not need to read this chapter. Refer to the chapter "Sequence Grabber Components" in this book for information about sequence grabber components and how to display the settings dialog box to the user.
As components, sequence grabber panel components rely on the facilities of the Component Manager. In order to use any component, your application must also use the Component Manager. If you are not familiar with this manager, see the chapter "Component Manager" in Inside Macintosh: More Macintosh Toolbox . In addition, you should be familiar with sequence grabber components and sequence grabber channel components. See the chapters "Sequence Grabber Components" and "Sequence Grabber Channel Components" in this book for more information.
The text in this chapter makes numerous references to sequence grabber components, sequence grabber channel components, and sequence grabber panel components. For the sake of brevity, shortened names have been adopted for each of these components. Consequently, you will often find sequence grabber components referred to as sequence grabbers ; sequence grabber channel components as channel components ; and sequence grabber panel components as panel components .
