  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`.

  - ### Method Detail

    - #### createUI

          public static ComponentUI createUI(JComponent c)

      Creates a UI for a JTextField.
      Parameters:
        `c` - the text field
      Returns:
        the UI object

    - #### getContext

          public SynthContext getContext(JComponent c)

      Returns the Context for the specified component.
      Specified by:
        `getContext` in interface `SynthUI`
      Parameters:
        `c` - Component requesting SynthContext.
      Returns:
        SynthContext describing component.

    - #### update

          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.

      Overrides:
        `update` in class `BasicTextUI`
      Parameters:
        `g` - the `Graphics` object used for painting
        `c` - the component being painted
      See Also:
        `paint(SynthContext,Graphics)`

    - #### paint

          protected void paint(SynthContext context,
                               Graphics g)

      Paints the specified component.

      This is routed to the `BasicTextUI.paintSafely(java.awt.Graphics)` method under the guarantee that the model does not change from the view of this thread while it is rendering (if the associated model is derived from `AbstractDocument`). This enables the model to potentially be updated asynchronously.

      Parameters:
        `context` - context for the component being painted
        `g` - the `Graphics` object used for painting
      See Also:
        `update(Graphics,JComponent)`

    - #### paintBorder

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

      Paints the border.
      Specified by:
        `paintBorder` in interface `SynthUI`
      Parameters:
        `context` - a component context
        `g` - `Graphics` to paint on
        `x` - the X coordinate
        `y` - the Y coordinate
        `w` - width of the border
        `h` - height of the border

    - #### paintBackground

          protected void paintBackground(Graphics g)

      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.
      Overrides:
        `paintBackground` in class `BasicTextUI`
      Parameters:
        `g` - the graphics context

    - #### propertyChange

          protected void propertyChange(PropertyChangeEvent evt)

      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 do nothing (i.e. the response to properties in JTextComponent itself are handled prior to calling this method).
      Overrides:
        `propertyChange` in class `BasicTextUI`
      Parameters:
        `evt` - the property change event

    - #### installDefaults

          protected void installDefaults()

      Initializes component properties, such as font, foreground, background, caret color, selection color, selected text color, disabled text color, and border color. The font, foreground, and background properties are only set if their current value is either null or a UIResource, other properties are set if the current value is null.
      Overrides:
        `installDefaults` in class `BasicTextUI`
      See Also:
        `BasicTextUI.uninstallDefaults()`, `BasicTextUI.installUI(javax.swing.JComponent)`

    - #### uninstallDefaults

          protected void 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`.
      Overrides:
        `uninstallDefaults` in class `BasicTextUI`
      See Also:
        `BasicTextUI.installDefaults()`, `BasicTextUI.uninstallUI(javax.swing.JComponent)`
