Public Functions Documentation

BlockTransition

BlockTransition	(			)

Initializes a new instance of the BlockTransition class.

Parameters:

transitionSteps	(Optional) Number of steps in the transition animation.

handleTickEvent

virtual void handleTickEvent	(			)

Handles the tick event when transitioning.

It uncovers and invalidates two blocks in every frame, for a total of 24 frames.

Reimplements: touchgfx::Transition::handleTickEvent

init

virtual void init	(			)

Initializes the transition.

Called after the constructor is called, when the application changes the transition.

Reimplements: touchgfx::Transition::init

invalidate

virtual void invalidate	(			)

Block transition does not require an invalidation.

Invalidation is handled by the class. Do no invalidation initially.

Reimplements: touchgfx::Transition::invalidate

tearDown

virtual void tearDown	(			)

Tears down the Animation.

Called before the destructor is called, when the application changes the transition.

Reimplements: touchgfx::Transition::tearDown
