Figure 12-1. CompRunner showing DrawStringDemo2 (left) and javax.swing.JTree (right)

Because little of this relates to the material in this chapter, I don't show the source for Com-
pRunner ; however, it's included in the gui directory of the javasrc code examples for the
book.

Drawing Text

Problem

You need to draw text in a component.

Solution

Simply call the drawString() method in the Graphics class:

public public class class DrawStringDemo DrawStringDemo extends extends JComponent {

private private static static final final long long serialVersionUID = - 7199469682507443122L ;

int int textX = 10 , textY = 20 ;

@Override
public

public void void paintComponent ( Graphics g ) {

g . drawString ( "Hello Java" , textX , textY );

}

public public Dimension getPreferredSize () {

return

return new new Dimension ( 100 , 100 );
