update

public void update(Graphics g,
 JComponent c)

Description copied from class: ComponentUI

Notifies this UI delegate that it is time to paint the specified component. This method is invoked by JComponent when the specified component is being painted.

By default this method fills the specified component with its background color if its opaque property is true, and then immediately calls paint. In general this method need not 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 context in which to paint

c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components

See Also:

• ComponentUI.paint(java.awt.Graphics, javax.swing.JComponent)
• JComponent.paintComponent(java.awt.Graphics)

Parameters:

g - the graphics context in which to paint

tabPlacement - the placement (left, right, bottom, top) of the tab

tabIndex - the index of the tab with respect to other tabs

x - the x coordinate of tab

y - the y coordinate of tab

w - the width of the tab

h - the height of the tab

isSelected - a boolean which determines whether or not the tab is selected

getTabLabelShiftX

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

Overridden to do nothing for the Java L&F.

Overrides:

getTabLabelShiftX in class BasicTabbedPaneUI

Parameters:

tabIndex - the tab index

isSelected - selection status

Returns:

the tab label shift x

getTabLabelShiftY

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

Overridden to do nothing for the Java L&F.

Overrides:

getTabLabelShiftY in class BasicTabbedPaneUI

Parameters:

tabPlacement - the tab placement

tabIndex - the tab index

isSelected - selection status

Returns:

the tab label shift y

getBaselineOffset

protected int getBaselineOffset()

Returns the amount the baseline is offset by. This is typically the same as getTabLabelShiftY.

Parameters:

g - the Graphics context in which to paint
