WipeTransition

A Transition that expands the new screen over the previous from the given direction. This transition only draws the pixels in the framebuffer once, and never moves any pixels. It is therefore very usefull on MCUs with limited performance.

Public Functions Documentation#

handleTickEvent#

virtual void handleTickEvent()

Handles the tick event when transitioning.

It uncovers and invalidates increasing parts of the new screen elements.

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()

Wipe 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

WipeTransition#

WipeTransition(const uint8_ttransitionSteps =20)

Initializes a new instance of the WipeTransition class.

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