    • 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

      Paints the tab background.
      Overrides:

      y - the y coordinate of tab
      w - the width of the tab
      h - the height of the tab

      Overrides:
      paint in class BasicTabbedPaneUI
      Parameters:
      g - the Graphics context in which to paint
