I have a JTree, and each tree node associates with a tooltip. I do not know how to break the tooltip(which is a string) to mutiple lines since my tooltip is pretty long......
Thanks a lot,

I think you have to use a customized look and feel to accomplish a multiline tooltip.
Or take a look at what Zafir Anjum came up with:

Or take a look at DTooltip, part of dog.gui.
I found lots of solutions with a quick google search.

I thought that HTML was allowed in the tooltip see the Swing demo provided in the SDK. You can use " " to simply add a new line I think.

Thank you very much, the tooltip breaks to multiple lines when I use HTML tag, but the tooltip font is much bigger than the regular tooltip without HTML tags. Do you know why?

I thought an html tag would work, but when I add to my tooltip text, it just displays with the rest of the text (all on one line). I'm probably doing something obviously wrong, but what is it?

I think you also need to include the <html> and </html> tags. I tried, it works perfect. Also you can use other html snippets to define the tooltip font size, color etc...
Thank you all.

Hi Dick, here is the code, use instead.
import javax.swing.JFrame ;
import javax.swing.JButton ;
import java.awt.FlowLayout ;
public class FooFrame extends JFrame
{
private void constructGUI()
{
JButton button = new JButton( "Button" ) ;
button.setToolTipText("<html>This isTooltip text.</html>");
getContentPane().setLayout( new FlowLayout() ) ;
getContentPane().add( button ) ;
}

public static void main( String[] args )
{
FooFrame f = new FooFrame() ;
f.setSize( 200 , 200 ) ;
f.constructGUI() ;
f.setVisible( true ) ;
}
}
