Card Layout

Using Card Layout

The CardLayout allows you to create the rough equivalent of a "tabbed dialog," which in more sophisticated environments has actual file-folder tabs running across one edge, and all you have to do is press a tab to bring forward a different dialog. Not so in the AWT: The CardLayout is simply a blank space and you’re responsible for bringing forward new cards

Here is an example to show how Card Layout works

import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class cardlayout extends Applet implements ActionListener, MouseListener {
Checkbox Win98,winNT,solaris,mac;
Panel oscards;
CardLayout cardlo;
Button win,other;
public void init()
{
win=new Button("Windows");
other=new Button("Other");
add(win);
add(other);
cardlo=new CardLayout();
oscards=new Panel();
oscards.setLayout(cardlo);
Win98=new Checkbox("Windows 98",null,true);
winNT=new Checkbox("Windows NT");
solaris=new Checkbox("Solaris");
mac=new Checkbox("MacOS");
Panel winpan=new Panel();
winpan.add(Win98);
winpan.add(winNT);
Panel otherpan=new Panel();
otherpan.add(solaris);
otherpan.add(mac);
oscards.add(winpan,"Windows");
oscards.add(otherpan,"Other");
add(oscards);
win.addActionListener(this);
other.addActionListener(this);
addMouseListener(this);
}
public void mousePressed(MouseEvent me) {
cardlo.next(oscards);
}
public void mouseClicked(MouseEvent me) {
}
public void mouseEntered(MouseEvent me) {
}
public void mouseExited(MouseEvent me) {
}
public void mouseReleased(MouseEvent me) {
}
public void actionPerformed(ActionEvent ae) {
if(ae.getSource() == win) {
cardlo.show(oscards,"Windows");
}
else
{
cardlo.show(oscards,"Other");
}
}
}
