All Implemented Interfaces:

PropertyChangeListener, EventListener

public class VerticalLabelUI
extends BasicLabelUI

A UI delegate for JLabel that rotates the label 90º

Extends BasicLabelUI.

The only difference between the appearance of labels in the Basic and Metal L&Fs is the manner in which disabled text is painted. As VerticalLabelUI does not override the method paintDisabledText, this class can be adapted for Metal L&F by extending MetalLabelUI instead of BasicLabelUI.

No other changes are required.

Method Summary

Modifier and Type	Method and Description
static ComponentUI	createUI(JComponent c)
int	getBaseline(JComponent c, int width, int height) Overridden to always return -1, since a vertical label does not have a meaningful baseline.
Component.BaselineResizeBehavior	getBaselineResizeBehavior(JComponent c) Overridden to always return Component.BaselineResizeBehavior.OTHER, since a vertical label does not have a meaningful baseline
Dimension	getMaximumSize(JComponent c) Returns a Dimension appropriate for vertical rendering
Dimension	getMinimumSize(JComponent c) Returns a Dimension appropriate for vertical rendering
Dimension	getPreferredSize(JComponent c) Returns a Dimension appropriate for vertical rendering
protected String	layoutCL(JLabel label, FontMetrics fontMetrics, String text, Icon icon, Rectangle viewR, Rectangle iconR, Rectangle textR) Transposes the view rectangles as appropriate for a vertical view before invoking the super method and copies them after they have been altered by SwingUtilities.layoutCompoundLabel(FontMetrics, String, Icon, int, int, int, int, Rectangle, Rectangle, Rectangle, int)
void	paint(Graphics g, JComponent c) Transforms the Graphics for vertical rendering and invokes the super method.
