IUIAnimationStoryboardEventHandler::OnStoryboardUpdated method
Handles events that occur when a storyboard is updated.
Syntax
HRESULT OnStoryboardUpdated(
[in] IUIAnimationStoryboard *storyboard
);
Parameters
- storyboard [in]
-
The storyboard that has been updated.
Return value
If the method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See Windows Animation Error Codes for a list of error codes.
Remarks
This method is called when the value of at least one of the variables that a storyboard is animating has changed since the last call to the IUIAnimationManager::Update method.
By default, a call made in a callback method to any other animation method results in the call failing and returning UI_E_ILLEGAL_REENTRANCY. However, there are exceptions to this default. The following methods can be successfully called from OnStoryboardUpdated:
- IUIAnimationManager::GetStoryboardFromTag
- IUIAnimationManager::GetVariableFromTag
- IUIAnimationStoryboard::GetTag
- IUIAnimationVariable::GetCurrentStoryboard
- IUIAnimationVariable::GetFinalIntegerValue
- IUIAnimationVariable::GetFinalValue
- IUIAnimationVariable::GetIntegerValue
- IUIAnimationVariable::GetPreviousIntegerValue
- IUIAnimationVariable::GetPreviousValue
- IUIAnimationVariable::GetTag
- IUIAnimationVariable::GetValue
