public class JProgressBar
extends JComponent
implements SwingConstants
A control that displays an integer value within a bounded interval. A progress bar typically communicates the progress of an event by displaying its percentage of completion. The orientation of the progress bar depends on its size; i.e. if its height is greater than its width, it is vertical.

Constructors

o JProgressBar 
 public JProgressBar()
Creates a horizontal progress bar with a border.

Methods

o update 
 public void update(Graphics g)
Overridden to call paint without filling the background.

Overrides:
update in class Container
o getOrientation 
 public int getOrientation()
Returns JProgressBar.VERTICAL or JProgressBar.HORIZONTAL depending on the orientation of the progress bar. A progress bar's default orientation is HORIZONTAL.

Returns:
HORIZONTAL or VERTICAL
o setOrientation 
 public void setOrientation(int newOrientation)
Sets the progress bar's orientation to newOrientation, which must be JProgressBar.VERTICAL or JProgressBar.HORIZONTAL. A progress bar's default orientation is HORIZONTAL.

Parameters:
newOrientation - HORIZONTAL or VERTICAL
Throws: IllegalArgumentException
if newOrientation is an illegal value
o isBorderPainted 
 public boolean isBorderPainted()
Returns true if the progress bar has a border or false if it does not.

Returns:
whether the progress bar has a border
See Also:
setBorderPainted
o setBorderPainted 
 public void setBorderPainted(boolean b)
Sets whether the progress bar should have a border.

Parameters:
b - true if the progress bar should have a border
See Also:
isBorderPainted
o isBackgroundPainted 
 public boolean isBackgroundPainted()
Returns true if the progress bar is painting its background or false if it does not.

Returns:
whether the progress bar draws its background
See Also:
setBackgroundPainted
o isOpaque 
 public boolean isOpaque()
Overrides:
isOpaque in class JComponent
o setBackgroundPainted 
 public void setBackgroundPainted(boolean b)
Sets whether the progress bar should paint its background.

Parameters:
b - true if the progress bar should paint its background
See Also:

o getUI 
 public ProgressBarUI getUI()
o setUI 
 public void setUI(ProgressBarUI ui)
o updateUI 
 public void updateUI()
Called to replace the UI with the latest version from the default UIFactory.

Overrides:
updateUI in class JComponent
o createChangeListener 
 protected ChangeListener createChangeListener()
o addChangeListener 
 public void addChangeListener(ChangeListener l)
o removeChangeListener 
 public void removeChangeListener(ChangeListener l)
o getModel 
 public BoundedRangeModel getModel()
o setModel 
 public void setModel(BoundedRangeModel newModel)
o getValue 
 public int getValue()
Returns the value. The value is always between the minimum and maximum, inclusive.

Returns:
the value
See Also:
setValue
o getMinimum 
 public int getMinimum()
Returns:
the minimum
See Also:
setMinimum
o getMaximum 
 public int getMaximum()
Returns:
the maximum
See Also:
setMaximum
o setValue 
 public void setValue(int n)
Sets the value to x. If x is less than the minimum or greater than the maximum, this method throws IllegalArgumentException and the value is not changed.

Notifies any listeners if the data changes.

Parameters:
x - the new value
Throws: IllegalArgumentException
if x is outside the legal range
See Also:
getValue
o setMinimum 
 public void setMinimum(int n)
Sets the model's minimum to x. If the current maximum or value is outside of the new minimum, the maximum or value is adjusted accordingly.

Notifies any listeners if the data changes.

Parameters:
x - the new minimum
See Also:
getMinimum, addChangeListener
o setMaximum 
 public void setMaximum(int n)
Sets the maximum to x. If the current minimum or value is outside of the new maximum, the minimum or value is adjusted accordingly.
