Question

I’m having trouble with placing GUI components in an applet. I am looking for a way to place it using absolute coordinate and sizes.
Here’s what I’ve done:

public class app extends JApplet { 


public void init() {
    setSize(450,450);
    try {
        javax.swing.SwingUtilities.invokeAndWait(new Runnable() {
            public void run() {
                createGUI();
            }
        });
    } catch (Exception e) {
        System.err.println("Creation of swing components not finished");
    }


}

public void createGUI() {
    JMenuBar menubar = new JMenuBar();
    JMenu menuFile = new JMenu("File");
    JMenuItem openItem = new JMenuItem("Open");
    menuFile.add(openItem);
    menubar.add(menuFile);
    setJMenuBar(menubar);


    app_buttons ab = new app_buttons();
    add(ab.button1);
    add(ab.button2);
    add(ab.button3);
}



}



public class app_buttons {
    public JButton button1;
    public JButton button2;
    public JButton button3;

    public apptextbox() {
       button1 = new JButton("1");
               button1.setBounds(20,20,20,20);
       button2 = new JButton("2");
               button2.setBounds(60,60,20,20);
       button3 = new JButton("3");
               button3.setBounds(90,90,20,20);

    }
 }

I can’t figure out how to do it, either the components don’t show or they fit the whole applet area. I want to specify for all my buttons, textareas, etc exactly how big they are and exactly where they will be placed. I’ve looked at tutorials on the web but it dosn’t work, the components dont get displayed.

I don’t want buttons, textareas, etc to resize either. Everything just static where I indicate them. For example when creating a JTextArea with (15,35) in size; it dosn’t seem to matter because it resizes anyway.

Thanks

use

setLayout(null);

for your applet in your init().
