Method Details
-
createUI
Creates a new UI object for the given component.- Parameters:
c
- component to create UI object for- Returns:
- the UI object
-
installDefaults
Installs defaults for a viewport.- Parameters:
c
- aJViewport
object
-
installListeners
Installs listeners into the viewport.- Parameters:
c
- aJViewport
object
-
uninstallListeners
Uninstalls listeners from the viewport.- Parameters:
c
- aJViewport
object
-
uninstallDefaults
Uninstalls defaults from a viewport.- Parameters:
c
- aJViewport
object
-
getContext
Returns the Context for the specified component.- Specified by:
getContext
in interfaceSynthUI
- Parameters:
c
- Component requesting SynthContext.- Returns:
- SynthContext describing component.
-
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:
-
paintBorder
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
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
Paints the specified component. This implementation does nothing.- Parameters:
context
- context for the component being paintedg
- theGraphics
object used for painting- See Also:
-
propertyChange
This method gets called when a bound property is changed.- Specified by:
propertyChange
in interfacePropertyChangeListener
- Parameters:
e
- A PropertyChangeEvent object describing the event source and the property that has changed.
