Method Detail

animate

protected boolean animate(long passedTime,
                          long duration)

Description copied from class: ScreenChangeAnimation

Animates this animation.

Specified by:

animate in class ScreenChangeAnimation

Parameters:

passedTime - the passed time in milliseconds

duration - the maximum duration of this animation

Returns:

true when the animation should continue, when false is returned the animation will be stopped and the next screen will be shown instead.

ScreenChangeAnimation.calculateAnimationPoint(int, int, long, long)

paintAnimation

protected void paintAnimation(Graphics g)

Description copied from class: ScreenChangeAnimation

Paints the animation.

Specified by:

paintAnimation in class ScreenChangeAnimation

Parameters:

g - the graphics context

onShow

protected void onShow(Style style,
                      Display dsplay,
                      int width,
                      int height,
                      Displayable lstDisplayable,
                      Displayable nxtDisplayable,
                      boolean isForward)

Description copied from class: ScreenChangeAnimation

Starts the animation. Please note that an animation can be re-used for several screens. At the end of starting animation(long,long) is called before the painting starts.

Overrides:

onShow in class ScreenChangeAnimation

Parameters:

style - the associated style.

dsplay - the display, which is used for setting this animation

width - the screen's width

height - the screen's height

lstDisplayable - the screen that has been shown until now

nxtDisplayable - the next screen that should be displayed when this animation finishes (as a Displayable)

isForward - true when the animation should run in the normal direction/mode - false if it should run backwards
