public class JXButton
extends JButton

A Painter enabled subclass of JButton. This class supports setting the foreground and background painters of the button separately. By default, JXButton creates and installs two Painters; one for the foreground, and one for the background. These default Painters delegate to the installed UI delegate.

For example, if you wanted to blur just the text on the button, and let everything else be handled by the UI delegate for your look and feel, then you could:


  JXButton b = new JXButton("Execute");
  AbstractPainter fgPainter = (AbstractPainter)b.getForegroundPainter();
  StackBlurFilter filter = new StackBlurFilter();
  fgPainter.setFilters(filter);
 

If either the foreground painter or the background painter is set, then super.paintComponent() is not called. By setting botht he foreground and background painters to null, you get exactly the same painting behavior as JButton. By contrast, the Painters installed by default will delegate to the UI delegate, thus achieving the same look as a typical JButton, but at the cost of some additional painting overhead.

Method Detail

getBackgroundPainter

public Painter getBackgroundPainter()

setBackgroundPainter

public void setBackgroundPainter(Painter p)

getForegroundPainter

public Painter getForegroundPainter()

setForegroundPainter

public void setForegroundPainter(Painter p)

isPaintBorderInsets

public boolean isPaintBorderInsets()
Returns true if the background painter should paint where the border is or false if it should only paint inside the border. This property is true by default. This property affects the width, height, and intial transform passed to the background painter.


setPaintBorderInsets

public void setPaintBorderInsets(boolean paintBorderInsets)
Sets the paintBorderInsets property. Set to true if the background painter should paint where the border is or false if it should only paint inside the border. This property is true by default. This property affects the width, height, and intial transform passed to the background painter. This is a bound property.


paintComponent

protected void paintComponent(Graphics g)
Description copied from class: javax.swing.JComponent
Calls the UI delegate's paint method, if the UI delegate is non-null. We pass the delegate a copy of the Graphics object to protect the rest of the paint code from irrevocable changes (for example, Graphics.translate).

If you override this in a subclass you should not make permanent changes to the passed in Graphics. For example, you should not alter the clip Rectangle or modify the transform. If you need to do these operations you may find it easier to create a new Graphics from the passed in Graphics and manipulate it. Further, if you do not invoker super's implementation you must honor the opaque property, that is if this component is opaque, you must completely fill in the background in a non-opaque color. If you do not honor the opaque property you will likely see visual artifacts.

The passed in Graphics object might have a transform other than the identify transform installed on it. In this case, you might get unexpected results if you cumulatively apply another transform.

Overrides:
paintComponent in class JComponent
Parameters:
g - the Graphics object to protect
