Rotate JLabel containing a imgicon
I want to rotate a jlabel when its clicked. The label is containing a imgicon.
I have tried to do like
http://www.codeguru.com/java/articles/199.shtml
but the label dont rotate, just the image (i think).
The image image is a vertical filled rectangle, but when i try to click it, it becomes a square...
The code for adding the ship to the contentpane
ImageIcon img =new ImageIcon("bigship.gif");
JLabel jLship =new JLabel("ship", img, SwingConstants.LEFT );
jLship.setName("ship");
jLship.setBounds(
ship.getPosition().x * (jlPOpoGame.getWidth() / 11) + 5,
ship.getPosition().y * (jlPOpoGame.getHeight() / 11) + 5,
img.getIconWidth(),
img.getIconHeight());
getJPOwnGame().add(jLship ,new Integer(1), 0);
And the code for changing the label inside a mouselistener.
selected.setUI(new VerticalLabelUI(true));
And the code for the UI:
import java.awt.*;
import java.awt.geom.*;
import javax.swing.*;
import javax.swing.plaf.basic.*;
class VerticalLabelUIextends BasicLabelUI
{
static{
labelUI =new VerticalLabelUI(false);
}
protectedboolean clockwise;
VerticalLabelUI(boolean clockwise )
{
super();
this.clockwise = clockwise;
}
public Dimension getPreferredSize(JComponent c)
{
Dimension dim = super.getPreferredSize(c);
returnnew Dimension( dim.height, dim.width );
}
privatestatic Rectangle paintIconR =new Rectangle();
privatestatic Rectangle paintTextR =new Rectangle();
privatestatic Rectangle paintViewR =new Rectangle();
privatestatic Insets paintViewInsets =new Insets(0, 0, 0, 0);
publicvoid paint(Graphics g, JComponent c)
{
JLabel label = (JLabel)c;
String text = label.getText();
Icon icon = (label.isEnabled()) ? label.getIcon() : label.getDisabledIcon();
if ((icon ==null) && (text ==null)){
return;
}
FontMetrics fm = g.getFontMetrics();
paintViewInsets = c.getInsets(paintViewInsets);
paintViewR.x = paintViewInsets.left;
paintViewR.y = paintViewInsets.top;
// Use inverted height & width
paintViewR.height = c.getWidth() - (paintViewInsets.left + paintViewInsets.right);
paintViewR.width = c.getHeight() - (paintViewInsets.top + paintViewInsets.bottom);
paintIconR.x = paintIconR.y = paintIconR.width = paintIconR.height = 0;
paintTextR.x = paintTextR.y = paintTextR.width = paintTextR.height = 0;
String clippedText =
layoutCL(label, fm, text, icon, paintViewR, paintIconR, paintTextR);
Graphics2D g2 = (Graphics2D) g;
AffineTransform tr = g2.getTransform();
if( clockwise )
{
g2.rotate( Math.PI / 2 );
g2.translate( 0, - c.getWidth() );
}
else
{
g2.rotate( - Math.PI / 2 );
g2.translate( - c.getHeight(), 0 );
}
if (icon !=null){
icon.paintIcon(c, g, paintIconR.x, paintIconR.y);
}
if (text !=null){
int textX = paintTextR.x;
int textY = paintTextR.y + fm.getAscent();
if (label.isEnabled()){
paintEnabledText(label, g, clippedText, textX, textY);
}
else{
paintDisabledText(label, g, clippedText, textX, textY);
}
}
g2.setTransform( tr );
}
}
Why dont the JLabel rotate?
