extends BasicTabbedPaneUI

The Metal subclass of BasicTabbedPaneUI.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the `java.beans` package. Please see `XMLEncoder`.

### update

    public void update(Graphics g,
                       JComponent c)

  Description copied from class: `ComponentUI`
  Notifies this UI delegate that it's time to paint the specified component. This method is invoked by `JComponent` when the specified component is being painted. By default this method will fill the specified component with its background color (if its `opaque` property is `true`) and then immediately call `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)`

                                      int w,
                                      int h,
                                      boolean isSelected)

  Overrides:

  Overridden to do nothing for the Java L&F.

  Overrides:
    `getTabLabelShiftX` in class `BasicTabbedPaneUI`

### getTabLabelShiftY

    protected int getTabLabelShiftY(int tabPlacement,
                                    int tabIndex,

  Overridden to do nothing for the Java L&F.

  Overrides:
    `getTabLabelShiftY` in class `BasicTabbedPaneUI`

### getBaselineOffset

    protected int getBaselineOffset()

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

  Overrides:
    `getBaselineOffset` in class `BasicTabbedPaneUI`
  Returns:
    amount to offset the baseline by
  Since:
    1.6

### paint

    public void paint(Graphics g,
                      JComponent c)

  Description copied from class: `ComponentUI`
  Paints the specified component appropriate for the look and feel. This method is invoked from the `ComponentUI.update` method when the specified component is being painted. Subclasses should override this method and use the specified `Graphics` object to render the content of the component.

  Overrides:
    `paint` in class `BasicTabbedPaneUI`
  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
