Returns:
the UI object

installDefaults

protected void installDefaults()
Overrides:
installDefaults in class BasicTabbedPaneUI

installListeners

protected void installListeners()
Overrides:
installListeners in class BasicTabbedPaneUI

uninstallListeners

protected void uninstallListeners()
Overrides:
uninstallListeners in class BasicTabbedPaneUI

c - Component requesting SynthContext.
Returns:
SynthContext describing component.

Creates and returns a JButton that will provide the user with a way to scroll the tabs in a particular direction. The returned JButton must be instance of UIResource.

Overrides:
createScrollButton in class BasicTabbedPaneUI
Parameters:
direction - One of the SwingConstants constants: SOUTH, NORTH, EAST or WEST
Returns:
Widget for user to
See Also:
JTabbedPane.setTabPlacement(int), SwingConstants

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.

createMouseListener

protected MouseListener createMouseListener()

Overridden to keep track of whether the selected tab is also pressed.

Overrides:
createMouseListener in class BasicTabbedPaneUI

getTabLabelShiftX

protected int getTabLabelShiftX(int tabPlacement,
                                int tabIndex,
                                boolean isSelected)
Overrides:
getTabLabelShiftX in class BasicTabbedPaneUI

getTabLabelShiftY

protected int getTabLabelShiftY(int tabPlacement,
                                int tabIndex,
                                boolean isSelected)
Overrides:
getTabLabelShiftY in class BasicTabbedPaneUI

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)

getBaseline

protected int getBaseline(int tab)

Returns the baseline for the specified tab.

Overrides:
getBaseline in class BasicTabbedPaneUI
Parameters:
tab - index of tab to get baseline for
Returns:
baseline or a value < 0 indicating there is no reasonable baseline

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

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 BasicTabbedPaneUI
Parameters:
g - the Graphics object used for painting
c - the component being painted
See Also:
paint(SynthContext,Graphics)

paint

                            int tabPlacement,
                            int selectedIndex)

Description copied from class: BasicTabbedPaneUI
