Transition handler class.
Library: ilvmgr
This class handles linear transitions between two transformers. During the transition, it computes intermediate transformers by calling the IlvManagerLinearTransitionHandler::computeTransformers
method.
This class can used to give an animation effect when changing the transformer of a view connected to a manager. Instead of using directly manager methods such as IlvManager::setTransformer
, you can create an IlvManagerTransitionScheduler
with an IlvManagerLinearTransitionHandler
. The result will be the same, except that you will see the transitions between the current transformer of the view and the new transformer.
IlvManagerLinearTransitionHandler::IlvManagerLinearTransitionHandler | ( | IlBoolean | partialRedraw = IlTrue | ) |
Constructor.
Initializes a new instance of the IlvManagerLinearTransitionHandler
class.
partialRedraw | A Boolean value specifying whether the transition handler is using partial redraws between transitions. |
|
virtual |
Called to compute the intermediate transformers.
This method fills the oldT and curT parameters using the given rates of completion of the transition.
oldRate | The previous rate of completion of the transition. |
newRate | The next rate of completion of the transition. |
from | The source transformer. |
to | The destination transformer. |
oldT | The computed transformer corresponding to oldRate. |
curT | The computed transformer corresponding to newRate. |
|
virtual |
Called to do the transition from current to next transformers.
This method sets the next transformer on the view view, which is connected to the manager manager.
manager | The manager. |
view | The manager view. |
from | The source transformer of the transition. |
to | The destination transformer of the transition. |
current | The current transformer of the manager view view. |
next | The transformer that will be set on the manager view view. |
