4.1 Overview of the FDT Interfaces
The FDT interface specification includes the following objects:
- DTM
- BTM
- Presentation Objects
- DTMActiveXControl
- BTMActiveXControl
- FdtChannelActiveXControl
- FdtChannel
- Frame Application
The behavior of these objects and their interfaces are described in detail in this chapter. Developers building FDT objects for DTMs or parts of Frame Application like storage or communication objects must implement the functionality defined in this chapter.
This chapter also references and defines expected behavior of both standard COM interfaces and FDT specific interfaces that FDT compliant objects must implement.
