Returns:

an enumeration of the views of this composite view.

scale

public void scale(double sx,
                  double sy)

Scales all children of container in relation to old values.

Overrides:

mode - mode to arrange new element relative previous: Abrevations:

  X_RL
  | ||
  | |--- boundary of new element
  | ---- boundary of minimal rectangle, described all
