    • getContext

      public SynthContext getContext(JComponent c)
      Returns the Context for the specified component.
      Specified by:
      getContext in interface SynthUI

      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 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 BasicButtonUI
      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

    • getDefaultIcon

      protected Icon getDefaultIcon(AbstractButton b)
      Returns the default icon. This should not callback to the JComponent.
      Parameters:
      b - button the icon is associated with
      Returns:
      default icon

    • getIcon

      protected Icon getIcon(AbstractButton b)
      Returns the Icon to use for painting the button. The icon is chosen with respect to the current state of the button.
      Parameters:
      b - button the icon is associated with
      Returns:
      an icon

    • 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 BasicButtonUI
      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:
      a Dimension object or null
      See Also:

    • 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 BasicButtonUI
      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:

    • 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 BasicButtonUI
      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:
      a Dimension object or null
      See Also:

    • getSizingIcon

      protected Icon getSizingIcon(AbstractButton b)
      Returns the Icon used in calculating the preferred/minimum/maximum size.
      Parameters:
      b - specifies the AbstractButton used when calculating the preferred/minimum/maximum size.
      Returns:
      the Icon used in calculating the preferred/minimum/maximum size.

    • 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.
