The mover transition is a transition that animates an object across the
display. For example, an application could wrap a mover transition around
an image widget, then begin moving that images vertically, horizontally or
diagonally across the display, specifying each movement as a series of
point-to-point destinations. The mover transition places the target object
at a particular location (relative to a container that defines the
movement's coordinate plane), then gradually moves the target object in a
linear manner to a final destination location.
For this transition to work properly, the target widget must be in a
To create a mover transition, an application would do the following:
1. Create the object that will be the target of the mover transition
2. Call ISHELL_CreateInstance() with a class ID of
AEECLSID_Transition2_Mover to retrieve a reference counted instance
of the mover transition.
3. Call Transition2Mover_Init() to setup the initialize the mover's
custom properties, including the widget it is to wrap, the container
holding the widget, and the starting and ending coordinates.
4. Call ITransitionMgr_Add() to add the transition to a manager.
This class will free itself if the reference count reaches zero.
