Constructor Details

SynthSplitPaneUI

public SynthSplitPaneUI()
Constructs a SynthSplitPaneUI.

Method Details

createUI

public static ComponentUI createUI(JComponent x)
Creates a new SynthSplitPaneUI instance
Parameters:
x - component to create UI object for
Returns:
the UI object

installDefaults

protected void installDefaults()
Installs the UI defaults.
Overrides:
installDefaults in class BasicSplitPaneUI

installListeners

protected void installListeners()
Installs the event listeners for the UI.
Overrides:
installListeners in class BasicSplitPaneUI

uninstallDefaults

protected void uninstallDefaults()
Uninstalls the UI defaults.
Overrides:
uninstallDefaults in class BasicSplitPaneUI

uninstallListeners

protected void uninstallListeners()
Uninstalls the event listeners from the UI.
Overrides:
uninstallListeners in class BasicSplitPaneUI

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.

propertyChange

public void propertyChange(PropertyChangeEvent e)
This method gets called when a bound property is changed.
Specified by:
propertyChange in interface PropertyChangeListener
Parameters:
e - A PropertyChangeEvent object describing the event source and the property that has changed.

createDefaultDivider

public BasicSplitPaneDivider createDefaultDivider()
Creates the default divider.
Overrides:
createDefaultDivider in class BasicSplitPaneUI
Returns:
the default divider

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

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

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:

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
