Constructor Details

SynthToolBarUI

public SynthToolBarUI()
Constructs a SynthToolBarUI.

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

createLayout

protected LayoutManager createLayout()
Creates a LayoutManager to use with the toolbar.
Returns:
a LayoutManager instance

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

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:

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

setBorderToNonRollover

protected void setBorderToNonRollover(Component c)
This implementation does nothing, because the rollover property of the JToolBar class is not used in the Synth Look and Feel.
Overrides:
setBorderToNonRollover in class BasicToolBarUI
Parameters:
c - component which will have a non-rollover border installed
See Also:

setBorderToRollover

protected void setBorderToRollover(Component c)
This implementation does nothing, because the rollover property of the JToolBar class is not used in the Synth Look and Feel.
Overrides:
setBorderToRollover in class BasicToolBarUI
Parameters:
c - component which will have a rollover border installed
See Also:

setBorderToNormal

protected void setBorderToNormal(Component c)
This implementation does nothing, because the rollover property of the JToolBar class is not used in the Synth Look and Feel.
Overrides:
setBorderToNormal in class BasicToolBarUI
Parameters:
c - component which will have a normal border re-installed
See Also:

paint

protected void paint(SynthContext context, Graphics g)
Paints the toolbar.
Parameters:
context - context for the component being painted
g - the Graphics object used for painting
See Also:

paintContent

protected void paintContent(SynthContext context, Graphics g, Rectangle bounds)
Paints the toolbar content.
Parameters:
context - context for the component being painted
g - Graphics object used for painting
bounds - bounding box for the toolbar
