Method Details- 
createUICreates a new UI object for the given component.- Parameters:
- c- component to create UI object for
- Returns:
- the UI object
 
- 
installDefaultsInstalls defaults for a viewport.- Parameters:
- c- a- JViewportobject
 
- 
installListenersInstalls listeners into the viewport.- Parameters:
- c- a- JViewportobject
 
- 
uninstallListenersUninstalls listeners from the viewport.- Parameters:
- c- a- JViewportobject
 
- 
uninstallDefaultsUninstalls defaults from a viewport.- Parameters:
- c- a- JViewportobject
 
- 
getContextReturns the Context for the specified component.- Specified by:
- getContextin interface- SynthUI
- Parameters:
- c- Component requesting SynthContext.
- Returns:
- SynthContext describing component.
 
- 
updateNotifies 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 paintmethod.- Overrides:
- updatein class- ComponentUI
- Parameters:
- g- the- Graphicsobject used for painting
- c- the component being painted
- See Also:
 
- 
paintBorderPaints the border. The method is never called, because theJViewportclass does not support a border. This implementation does nothing.- Specified by:
- paintBorderin interface- SynthUI
- Parameters:
- context- a component context
- g- the- Graphicsto paint on
- x- the X coordinate
- y- the Y coordinate
- w- width of the border
- h- height of the border
 
- 
paintPaints 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:
- paintin class- ComponentUI
- Parameters:
- g- the- Graphicsobject used for painting
- c- the component being painted
- See Also:
 
- 
paintPaints the specified component. This implementation does nothing.- Parameters:
- context- context for the component being painted
- g- the- Graphicsobject used for painting
- See Also:
 
- 
propertyChangeThis method gets called when a bound property is changed.- Specified by:
- propertyChangein interface- PropertyChangeListener
- Parameters:
- e- A PropertyChangeEvent object describing the event source and the property that has changed.
