      the UI object

      Registers listeners.
      Overrides:
      installListeners in class BasicProgressBarUI

      protected void uninstallListeners()
      Removes all listeners installed by this object.
      Overrides:
      uninstallListeners in class BasicProgressBarUI

    • installDefaults

      protected void installDefaults()
      Installs default properties.
      Overrides:
      installDefaults in class BasicProgressBarUI

    • uninstallDefaults

      protected void uninstallDefaults()
      Unintalls default properties.
      Overrides:
      uninstallDefaults in class BasicProgressBarUI

    • 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.

    • getBaseline

      public int getBaseline(JComponent c, int width, int height)
      Returns the baseline.
      Overrides:
      getBaseline in class BasicProgressBarUI
      Parameters:
      c - JComponent baseline is being requested for
      width - the width to get the baseline for
      height - the height to get the baseline for
      Returns:
      baseline or a value < 0 indicating there is no reasonable baseline

    • getBox

      protected Rectangle getBox(Rectangle r)
      Stores the position and size of the bouncing box that would be painted for the current animation index in r and returns r. Subclasses that add to the painting performed in this class's implementation of paintIndeterminate -- to draw an outline around the bouncing box, for example -- can use this method to get the location of the bouncing box that was just painted. By overriding this method, you have complete control over the size and position of the bouncing box, without having to reimplement paintIndeterminate.
      Overrides:
      getBox in class BasicProgressBarUI
      Parameters:
      r - the Rectangle instance to be modified; may be null
      Returns:
      null if no box should be drawn; otherwise, returns the passed-in rectangle (if non-null) or a new rectangle

    • setAnimationIndex

      protected void setAnimationIndex(int newValue)
      Sets the index of the current animation frame to the specified value and requests that the progress bar be repainted. Subclasses that don't use the default painting code might need to override this method to change the way that the repaint method is invoked.
      Overrides:
      setAnimationIndex in class BasicProgressBarUI
      Parameters:
      newValue - the new animation index; no checking is performed on its value

    • 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 ComponentUI
      Parameters:
      g - the Graphics object used for painting
      c - the component being painted
      See Also:

    • paint

      public void paint(Graphics g, JComponent c)
      Paints the specified component according to the Look and Feel.

      This method is not used by Synth Look and Feel. Painting is handled by the paint(SynthContext,Graphics) method.

      Overrides:
      paint in class BasicProgressBarUI
      Parameters:
      g - the Graphics object used for painting
      c - the component being painted
      See Also:

    • 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:

    • paintText

      protected void paintText(SynthContext context, Graphics g, String title)
      Paints the component's text.
      Parameters:
      context - context for the component being painted
      g - Graphics object used for painting
      title - the text to paint

    • 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

      public void propertyChange(PropertyChangeEvent e)
      This method gets called when a bound property is changed.
      Specified by:
      propertyChange in interface PropertyChangeListener
      Parameters:
      e - A PropertyChangeEvent object describing the event source and the property that has changed.

    • getPreferredSize

      public Dimension getPreferredSize(JComponent c)
      Returns the specified component's preferred size appropriate for the look and feel. If null is returned, the preferred size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method returns null.
      Overrides:
      getPreferredSize in class BasicProgressBarUI
      Parameters:
      c - the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
      Returns:
      a Dimension object containing given component's preferred size appropriate for the look and feel
