MAnimFreeTimerWindowFunctions

Support

Supported from 5.1

Description

Free timer animation utility functions interface. The class inherits functions from MAnimWindowFunctions, and defines the additional interface required for window operations which support animations with their own timers.

You do NOT have to create an object of this type. The class is implemented by the window server, and provides utility functions to all CFreeTimerWindowAnim derived classes via the WindowFunctions() member.

It is not intended for user derivation.

Note:

• The classes’ functions are declared as pure virtual in the header file. However, as stated above, you do not need to derive from this class, so these have not been marked as pure virtual in this document.
