JTextArea Rotation & WordWrap -- Challenging issue.

Hi all,

My aim is to rotate the text on a JTextarea. With the below code I could do the rotation. But now the problem is that I'am unable to set wordwrapping on the same as I have overriden the paintComponent method. It just puts everything in one line.

String sText = "I have changed your graphics. How can I set the wordwrapping on you ?";

JTextArea jTextArea = new JTextArea(){
public void paintComponent(Graphics g) {

super.paintComponent(g);

Graphics2D g2d = (Graphics2D) g;
g2d.translate( getWidth()/2, getHeight() );
g2d.rotate( Math.toRadians(270) );

g2d.drawString(sText, 0, 0);

}
};

We have got a release and I'am stuck with this.
Any suggestions would be greatly helpful.

Thankyou,
Sainath Veepuri

Ouch. You're going to need to break the lines and do the wrapping yourself. You should be able to use a LineBreakMeasurer to determine where to break each line. Instead of drawing strings, you'll be working with TextLayout objects. It's a bit more work, but you'll have all the flexibility you need.

Take a look at the Java2D tutorial on text: http://java.sun.com/developer/onlineTraining/Media/2DText/style.html

It's challenging to do this "right" but it's
not so tough to do something quick and dirty
that can break lines on its own.
