Creates a new UI object for the given component.

Parameters:

c - component to create UI object for

Returns:

the UI object

installDefaults

protected void installDefaults()

Installs the defaults.

Overrides:

installDefaults in class BasicTabbedPaneUI

installListeners

protected void installListeners()

Installs the listeners.

Overrides:

installListeners in class BasicTabbedPaneUI

uninstallListeners

protected void uninstallListeners()

Uninstalls the listeners.

Overrides:

uninstallListeners in class BasicTabbedPaneUI

Specified by:

getContext in interface SynthUI

Parameters:

c - Component requesting SynthContext.

Returns:

SynthContext describing component.

createScrollButton

protected JButton createScrollButton(int direction)

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()

Creates a mouse listener. Overridden to keep track of whether the selected tab is also pressed.

Overrides:

createMouseListener in class BasicTabbedPaneUI

Returns:

a mouse listener

getTabLabelShiftX

protected int getTabLabelShiftX(int tabPlacement,
 int tabIndex,
 boolean isSelected)

Returns the tab label shift x.

Overrides:

getTabLabelShiftX in class BasicTabbedPaneUI

Parameters:

tabPlacement - the tab placement

tabIndex - the tab index

isSelected - selection status

Returns:

the tab label shift x

getTabLabelShiftY

protected int getTabLabelShiftY(int tabPlacement,
 int tabIndex,
 boolean isSelected)

Returns the tab label shift y.

Overrides:

getTabLabelShiftY in class BasicTabbedPaneUI

Parameters:

tabPlacement - the tab placement

tabIndex - the tab index

isSelected - selection status

Returns:

the tab label shift y

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

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 BasicTabbedPaneUI

Parameters:

g - the Graphics object used for painting

c - the component being painted

See Also:

• paint(SynthContext,Graphics)

paint

protected void paint(SynthContext context,

Paints the specified component.

Parameters:

context - context for the component being painted

g - the Graphics object used for painting

See Also:

• update(Graphics,JComponent)

paintTabArea

protected void paintTabArea(Graphics g,
 int tabPlacement,
 int selectedIndex)

Description copied from class: BasicTabbedPaneUI

Paints the tabs in the tab area. Invoked by paint(). The graphics parameter must be a valid Graphics object. Tab placement may be either: JTabbedPane.TOP, JTabbedPane.BOTTOM, JTabbedPane.LEFT, or JTabbedPane.RIGHT.

tabPlacement - the placement for the tabs within the JTabbedPane

selectedIndex - the tab index of the selected component

setRolloverTab

protected void setRolloverTab(int index)

Sets the tab the mouse is currently over to index. index will be -1 if the mouse is no longer over any tab. No checking is done to ensure the passed in index identifies a valid tab.

Overrides:

setRolloverTab in class BasicTabbedPaneUI

Parameters:

index - Index of the tab the mouse is over.

calculateMaxTabHeight

protected int calculateMaxTabHeight(int tabPlacement)
