      public SynthLabelUI()
      Constructs a SynthLabelUI.

  • Method Details

      the UI object

    • installDefaults

      protected void installDefaults(JLabel c)
      Installs default properties.
      Overrides:
      installDefaults in class BasicLabelUI
      Parameters:
      c - an instance of JLabel

    • uninstallDefaults

      protected void uninstallDefaults(JLabel c)
      Uninstalls default properties.
      Overrides:
      uninstallDefaults in class BasicLabelUI
      Parameters:
      c - an instance of JLabel

    • 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 BasicLabelUI
      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

    • 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 BasicLabelUI
      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:

    • 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

    • 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 BasicLabelUI
      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
      See Also:

    • getMinimumSize

      public Dimension getMinimumSize(JComponent c)
      Returns the specified component's minimum size appropriate for the look and feel. If null is returned, the minimum 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 invokes getPreferredSize and returns that value.
      Overrides:
      getMinimumSize in class BasicLabelUI
      Parameters:
      c - the component whose minimum 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:
      getPreferredSize(c)
      See Also:

    • getMaximumSize

      public Dimension getMaximumSize(JComponent c)
      Returns the specified component's maximum size appropriate for the look and feel. If null is returned, the maximum 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 invokes getPreferredSize and returns that value.
      Overrides:
      getMaximumSize in class BasicLabelUI
      Parameters:
      c - the component whose maximum 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:
      getPreferredSize(c)
      See Also:

    • propertyChange

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