Returns the Context for the specified component.

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.
getBox in class BasicProgressBarUI
r - the Rectangle instance to be modified; may be null
null if no box should be drawn; otherwise, returns the passed-in rectangle (if non-null) or a new rectangleBasicProgressBarUI.setAnimationIndex(int)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.
setAnimationIndex in class BasicProgressBarUI
newValue - the new animation index; no checking is performed on its valueBasicProgressBarUI.incrementAnimationIndex()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.

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.

e - A PropertyChangeEvent object describing the event source and the property that has changed.public Dimension getPreferredSize(JComponent c)
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.
getPreferredSize in class BasicProgressBarUI
c - the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple componentsJComponent.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)
