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

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
