The interfaces that are defined by the Windows SideShow platform API can be divided into two broad categories:
Interfaces that are implemented by the Windows SideShow platform.
Interfaces that are implemented by individual Windows SideShow gadgets.
This section describes the gadget-implemented interfaces.
The interfaces in these two categories work together. They often pass pointers back and forth, and calls to a method in one category often lead to a call back to a method or property in the other category.
The following table summarizes the Windows SideShow interfaces implemented by Windows SideShow gadgets and called by the Windows SideShow platform.
