protected Rectangle getBox(Rectangle r)
Stores the position and size of the bouncing box that would be painted for the current animation index in r
and returns r
. Subclasses that add to the painting performed in this class's implementation of paintIndeterminate
-- to draw an outline around the bouncing box, for example -- can use this method to get the location of the bouncing box that was just painted. By overriding this method, you have complete control over the size and position of the bouncing box, without having to reimplement paintIndeterminate
.

protected void setAnimationIndex(int newValue)
Sets the index of the current animation frame to the specified value and requests that the progress bar be repainted. Subclasses that don't use the default painting code might need to override this method to change the way that the repaint
method is invoked.

public void update(Graphics g, JComponent c)
Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls the paint(SynthContext,Graphics)
method.
In general, this method does not need to be overridden by subclasses. All Look and Feel rendering code should reside in the paint
method.

public void paint(Graphics g, JComponent c)
Paints the specified component according to the Look and Feel.
This method is not used by Synth Look and Feel. Painting is handled by the paint(SynthContext,Graphics)
method.

This method gets called when a bound property is changed.

Returns the specified component's preferred size appropriate for the look and feel. If null
is returned, the preferred size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method returns null
.
