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.

createDefaultCellEditor

protected TreeCellEditor createDefaultCellEditor()

Creates a default cell editor.

Overrides:

createDefaultCellEditor in class BasicTreeUI

Returns:

a default cell editor

createDefaultCellRenderer

protected TreeCellRenderer createDefaultCellRenderer()

Returns the default cell renderer that is used to do the stamping of each node.

uninstallDefaults

protected void uninstallDefaults()

Uninstalls default properties.

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)

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

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 BasicTreeUI

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.

Parameters:

context - context for the component being painted

g - the Graphics object used for painting

See Also:

• update(Graphics,JComponent)

 Rectangle clipBounds,
 Insets insets,
 Rectangle bounds,
 TreePath path,
