clipY - absolute verical clipping start

clipWidth - clipping width

clipHeight - clipping height

g - the graphics context

setStyle

protected void setStyle(Style style)

Description copied from class: ContainerView

Sets the style for this view. The style can include additional parameters for the view. Subclasses should call super.setStyle(style) first.

Overrides:

setStyle in class ContainerView

Parameters:

style - the style

showNotify

public void showNotify()

Description copied from class: ContainerView

Notifies this view that it is about to be shown (again). The default implementation just sets the restartAnimation-field to true.

Overrides:

animate

public boolean animate()

Animates this view - the items appear to drop from above.

Overrides:
