Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.

`protected Dimension`	`getPreferredInnerVertical()`	Returns preferred size of the vertical `JProgressBar`.
`protected Color`	`getSelectionBackground()`	The "selectionBackground" is the color of the text when it is painted over an unfilled area of the progress bar.
`protected Color`	`getSelectionForeground()`	The "selectionForeground" is the color of the text when it is painted over a filled area of the progress bar.
`protected Point`	`getStringPlacement(Graphics g, String progressString, int x, int y, int width, int height)`	Designate the place where the progress string will be painted.
`protected void`	`incrementAnimationIndex()`	Sets the index of the current animation frame, to the next valid value, which results in the progress bar being repainted.
`protected void`	`installDefaults()`	Installs default properties.
`protected void`	`installListeners()`	Registers listeners.
`void`	`paint(Graphics g, JComponent c)`	Delegates painting to one of two methods: paintDeterminate or paintIndeterminate.
