Method Details
-
createUI
Creates a new UI object for the given component.- Parameters:
x
- component to create UI object for- Returns:
- the UI object
-
update
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

paint(SynthContext,Graphics)
method.- Overrides:
paint
in classComponentUI
- Parameters:
g
- theGraphics
object used for paintingc
- the component being painted- See Also:
-
paint

in interfaceSynthUI
- Parameters:
context
- a component contextg
-Graphics
to paint onx
- the X coordinatey
- the Y coordinatew

- height of the border
-
getContext
Returns the Context for the specified component.- Specified by:
getContext
in interfaceSynthUI
- Parameters:
c
- Component requesting SynthContext.- Returns:
- SynthContext describing component.
-
