[kumar.dinesh7]

i am drawing some component like rectangles on the applet window.....if i draw the component below the visible screen then applet window doesn't show that components.....how can i scroll the applet so that i can see below the visible screen by scrolling....??

i am using NETBEANS IDE for developing Applets.

Plz help me...

I've given you the link to the Oracle Swing tutorials at least twice before. If you were genuinely interested in learning, you would have had more than enough time to go through the entire tutorial trail and wouldn't still be asking silly questions.

I'll add that the NetBeans visual designer is categorically NOT a beginners' tool. Learn to hand-code GUIs first.

okay

import java.applet.*;
import java.awt.*;
import javax.swing.*;


class applet_opr extends Applet
{
    public void init()
            
    {      
        setBackground(Color.red);
    }
    
    public void paint(Graphics g)
    {
        g.drawRect(100, 100, 1200, 900);
    }
}


public class practical
{
    
public static void main(String[]args)
{
    
applet_opr pa=new applet_opr();
pa.init();

JScrollPane scrollBar=new JScrollPane(pa,JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);


JFrame frame=new JFrame("AddScrollBarToJFrame");

frame.setLayout(new BorderLayout());
frame.add(scrollBar);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(1000,700);
frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
frame.setVisible(true);

}
}

i tried this code....this code makes a scroll bar but scroll bar not working.

Find the tutorial on developing and deploying Applets and go through the section that deals with the Applet life cycle.

Also, don't unnecessarily mix AWT and Swing components. Why do you think you need to use an Applet for this code?

Additionally, I repeat my recommendation to go through the Swing tutorial systematically. Nothing in that code suggests that the scroll pane's content is larger than the viewport, so why should the scroll bars be active?

okay....can you provide me a better link where i can learn all this?

[DarrylBurke]

Not better than the one already given, no.
