Constructors

SynthTableHeaderUI

public SynthTableHeaderUI()

Methods

createUI

public static ComponentUI createUI(JComponent h)

Creates a new UI object for the given component.

Parameters:
h - component to create UI object for
Returns:
the UI object

installDefaults

protected void installDefaults()

Initializes JTableHeader properties such as font, foreground, and background. The font, foreground, and background properties are only set if their current value is either null or a UIResource, other properties are set if the current value is null.

Overrides:
installDefaults in class BasicTableHeaderUI
See Also:
BasicTableHeaderUI.installUI(javax.swing.JComponent)

installListeners

protected void installListeners()

Attaches listeners to the JTableHeader.

Overrides:
installListeners in class BasicTableHeaderUI

uninstallDefaults

protected void uninstallDefaults()
Overrides:
uninstallDefaults in class BasicTableHeaderUI

uninstallListeners

protected void uninstallListeners()
Overrides:
uninstallListeners in class BasicTableHeaderUI

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 BasicTableHeaderUI
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)

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

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.

rolloverColumnUpdated

protected void rolloverColumnUpdated(int oldColumn,
                                     int newColumn)

This method gets called every time when a rollover column in the table header is updated. Every look and feel that supports a rollover effect in a table header should override this method and repaint the header.

Overrides:
rolloverColumnUpdated in class BasicTableHeaderUI
Parameters:
oldColumn - the index of the previous rollover column or -1 if the mouse was not over a column
newColumn - the index of the new rollover column or -1 if the mouse is not over a column
See Also:
BasicTableHeaderUI.getRolloverColumn(), JTableHeader.getHeaderRect(int)

propertyChange

public void propertyChange(PropertyChangeEvent evt)

This method gets called when a bound property is changed.

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