Method Detail
createUI
public static ComponentUI createUI(JComponent c)
Creates a new UI object for the given component.- Parameters:
c
- component to create UI object for- Returns:
- the UI object
installDefaults
protected void installDefaults(JComponent c)
Installs defaults for a viewport.- Parameters:
c
- aJViewport
object
installListeners
protected void installListeners(JComponent c)
Installs listeners into the viewport.- Parameters:
c
- aJViewport
object
uninstallListeners
protected void uninstallListeners(JComponent c)
Uninstalls listeners from the viewport.- Parameters:
c
- aJViewport
object
uninstallDefaults
protected void uninstallDefaults(JComponent c)
Uninstalls defaults from a viewport.- Parameters:
c
- aJViewport
object
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 thepaint(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 classComponentUI
- Parameters:
g
- theGraphics
object used for paintingc
- the component being painted- See Also:
paint(SynthContext,Graphics)
paintBorder
public void paintBorder(SynthContext context, Graphics g, int x, int y, int w, int h)
Paints the border. The method is never called, because theJViewport
class does not support a border. This implementation does nothing.- Specified by:
paintBorder
in interfaceSynthUI
- Parameters:
context
- a component contextg
- theGraphics
to paint onx
- the X coordinatey
- the Y coordinatew
- width of the borderh
- height of the border
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 classComponentUI
- Parameters:
g
- theGraphics
object used for paintingc
- the component being painted- See Also:
paint(SynthContext,Graphics)
paint
protected void paint(SynthContext context, Graphics g)
Paints the specified component. This implementation does nothing.- Parameters:
context
- context for the component being paintedg
- theGraphics
object used for painting- See Also:
update(Graphics,JComponent)
