Take this simple Applet import java.applet.*;
import java.awt.*;
public class UnderlineText extends Applet{
String s = "Java Howto";
int x=20;
int y=50;
public void init() {
add(new Button("Real's"));
}
public void paint(Graphics g) {
g.drawString(s, x,y);
g.drawLine(x , y+2 , x+getFontMetrics(getFont()).stringWidth(s) , y+2 );
}
}
You use it with the following HTML <HTML>
<TABLE><TR><TD>
<APPLET CODE=UnderlineText.class WIDTH=100 HEIGHT=100>
</APPLET>
</HMTL>
To be able to use the same class as an application, we simply extend a Panel instead of an Applet, put it in Frame and call the init() method. import java.awt.*;
public class UnderlineText extends Panel{
String s = "Java Howto";
int x=20;
int y=50;
public static void main(String[] args) {
Frame f = new Frame();
f.addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent e) {
System.exit(0);
};
});
UnderlineText ut = new UnderlineText();
ut.setSize(100,100); // same size as defined in the HTML APPLET
f.add(ut);
f.pack();
ut.init();
f.setSize(100,100 + 20); // add 20, seems enough for the Frame title,
f.show();
}
public void init() {
add(new Button("Real's"));
}
public void paint(Graphics g) {
g.drawString(s, x,y);
g.drawLine(x , y+2 , x+getFontMetrics(getFont()).stringWidth(s) , y+2 );
}
}
