Class SynthTextAreaUI

  • All Implemented Interfaces:
    SynthConstants, SynthUI, ViewFactory


    public class SynthTextAreaUI
    extends BasicTextAreaUI
    implements SynthUI
    Provides the look and feel for a plain text editor in the Synth look and feel. In this implementation the default UI is extended to act as a simple view factory.

    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.

    • Constructor Detail

      • SynthTextAreaUI

        public SynthTextAreaUI()
    • Method Detail

      • createUI

        public static ComponentUI createUI(JComponent ta)
        Creates a UI object for a JTextArea.
        Parameters:
        ta - a text area
        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.
        Parameters:
        context - context for the component being painted
        g - the Graphics object used for painting
        See Also:
        update(Graphics,JComponent)
      • 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
      • 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
      • 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 rebuild the View when the WrapLine or the WrapStyleWord property changes.
        Overrides:
        propertyChange in class BasicTextAreaUI
        Parameters:
        evt - the property change event
