Defines an animation variable, which represents a visual element that can be animated.
Inheritance
The IUIAnimationVariable interface inherits from the IUnknown interface. IUIAnimationVariable also has these types of members:
Methods
The IUIAnimationVariable interface has these methods.
| IUIAnimationVariable::GetCurrentStoryboard Gets the storyboard that is currently animating the animation variable. |
| IUIAnimationVariable::GetFinalIntegerValue Gets the final value of the animation variable as an integer. This is the value after all currently scheduled animations have completed. |
| IUIAnimationVariable::GetFinalValue Gets the final value of the animation variable. This is the value after all currently scheduled animations have completed. (IUIAnimationVariable.GetFinalValue) |
| IUIAnimationVariable::GetIntegerValue Gets the current value of the animation variable as an integer. |
| IUIAnimationVariable::GetPreviousIntegerValue Gets the previous value of the animation variable as an integer. This is the value of the animation variable before the most recent update. |
| IUIAnimationVariable::GetPreviousValue Gets the previous value of the animation variable. This is the value of the animation variable before the most recent update. (IUIAnimationVariable.GetPreviousValue) |
| IUIAnimationVariable::GetTag Gets the tag for an animation variable. |
| IUIAnimationVariable::GetValue Gets the current value of the animation variable. |
| IUIAnimationVariable::SetLowerBound Sets the lower bound (floor) for the animation variable. The value of the animation variable should not fall below the specified value. |
| IUIAnimationVariable::SetRoundingMode Specifies the rounding mode for the animation variable. |
| IUIAnimationVariable::SetTag Sets the tag for an animation variable. |
| IUIAnimationVariable::SetUpperBound Sets an upper bound (ceiling) for the animation variable. The value of the animation variable should not rise above the specified value. |
| IUIAnimationVariable::SetVariableChangeHandler Specifies a variable change handler. This handler is notified of changes to the value of the animation variable. |
| IUIAnimationVariable::SetVariableIntegerChangeHandler Specifies an integer variable change handler. This handler is notified of changes to the integer value of the animation variable. |
Remarks
Along with IUIAnimationTransition and IUIAnimationStoryboard, IUIAnimationVariable is a primary component for building animations. To create and manage animation variables, use IUIAnimationManager.
