    • Constructor Detail

      • PuHistogram

        public PuHistogram(java.lang.String name,
                   PsUpdateIf parent)
        Create new instance with given name and parent. The name appears as label on the histogram, and the parent is informed whenever the histogram has changed using parent.update(this).
        Parameters:
        name - Name of histogram to appear as label in histogram.
        parent - Parent of histogram to receive update events.

    • Method Detail

      • init

        public void init()
        Assign default values, and may be used to reset instance.
        Overrides:
        init in class PsObject

      • reset

        public void reset()
        Reset the progress bar.

      • update

        public boolean update(java.lang.Object event)
        Description copied from class: PsObject
        Update all inspector panels, send update to all registered update listeners and finally update parent. Each of those updates has this object as event independent of the argument of this method.

        Central update method of this object. Must be overwritten if this class receives unknown events, say, from new children. Any subclass must class invoke super.update(event) on all events it does handle itself.

        Specified by:
        update in interface PsUpdateIf
        Overrides:
        update in class PsObject
        Parameters:
        event - carries a lot of information
        Returns:
        true if event has been handled, otherwise false
