Re: Erasing a String produced using drawString()
This is what I have so far
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class JBlueGray extends JApplet implements ActionListener
{
String fname = "Robert";
String lname = "McDougal";
JButton pushme = new JButton("Click Me!");
Font littlefont = new Font("Helvetica", Font.PLAIN, 12);
Font bigfont = new Font("Helvetica", Font.PLAIN, 22);
int x = 20, y = 50, width, count = 0, height;
public void init()
{
Container con = getContentPane();
con.setLayout(new FlowLayout());
con.add(pushme);
pushme.addActionListener(this);
}
public void actionPerformed(ActionEvent e)
{
Object source = e.getSource();
if (source == pushme) {
Graphics gr = getGraphics();
if (count == 1) {
gr.setFont(littlefont);
gr.setColor(Color.BLUE);
width = gr.getFontMetrics().stringWidth(fname);
height = gr.getFontMetrics().getHeight();
gr.drawString(fname, x, y);
gr.drawString(lname, x + (2 + width), y);
}
else if(count == 2) {
width += gr.getFontMetrics().stringWidth(lname);
gr.setFont(bigfont);
gr.setColor(Color.DARK_GRAY);
gr.fillRect(x, y, width + 4, height);
gr.drawString(fname, x, y);
gr.setFont(littlefont);
gr.setColor(Color.BLUE);
gr.drawString(lname,
gr.getFontMetrics().stringWidth(fname) + 2, y);
pushme.setEnabled(false);
}
}
}
}
