Constructor Details

SynthRootPaneUI

public SynthRootPaneUI()

Constructs a SynthRootPaneUI.

Method Details

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

getContext

public SynthContext getContext(JComponent c)

Returns the Context for the specified component.

Specified by:: getContext in interface SynthUI
Parameters:: c - Component requesting SynthContext.
Returns:: 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(SynthContext,Graphics)

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 ComponentUI

Parameters:

g - the Graphics object used for painting

c - 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 painted

g - the Graphics object used for painting

See Also:

update(Graphics,JComponent)

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

propertyChange

public void propertyChange(PropertyChangeEvent e)

Invoked when a property changes on the root pane. If the event indicates the defaultButton has changed, this will reinstall the keyboard actions.

Specified by:: propertyChange in interface PropertyChangeListener
Overrides:: propertyChange in class BasicRootPaneUI
Parameters:: e - A PropertyChangeEvent object describing the event source and the property that has changed.
