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 java.beans.XMLEncoder.

protected void paintBackground(Graphics g)

Overrides javax.swing.plaf.basic.BasicTextUI.paintBackground.

Doc from javax.swing.plaf.basic.BasicTextUI.paintBackground.

Paints a background for the view. This will only be called if isOpaque() on the associated component is true. The default is to paint the background color of the component. Overridden to do nothing.

public void paintBorder(SynthContext context, Graphics g, int x, int y, int w, int h)

Paints the border.

Annotations
@Override
propertyChangeback to summary
protected void propertyChange(PropertyChangeEvent evt)

Overrides javax.swing.plaf.basic.BasicTextAreaUI.propertyChange.

This method gets called when a bound property is changed on the associated JTextComponent. This is a hook which UI implementations may change to reflect how the UI displays bound properties of JTextComponent subclasses. This is implemented to rebuild the View when the WrapLine or the WrapStyleWord property changes.

Parameters
evt:PropertyChangeEvent

the property change event

uninstallDefaultsback to summary
protected void uninstallDefaults()

Overrides javax.swing.plaf.basic.BasicTextUI.uninstallDefaults.

Doc from javax.swing.plaf.basic.BasicTextUI.uninstallDefaults.

Sets the component properties that have not been explicitly overridden to null. A property is considered overridden if its current value is not a UIResource.

Annotations
@Override
updateback to summary
public void update(Graphics g, JComponent c)

Overrides javax.swing.plaf.basic.BasicTextUI.update.

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.

Parameters
g:Graphics

the Graphics object used for painting

c:JComponent

the component being painted
