JAVA Applet resize to load problem?

**Kratos321** · 05-10-2012, 02:52 PM

Hello everyone,

My problem in the following code is that the modified component only loads when I resize the applet window. When I add the "labelOne" label, it does not appear instantly but only when I resize the output applet. I'm not using the paint() method as I don't need it.

Any help/assistance would be greatly appreciated.
Cheers.

Java Code:

// The "ListenerTesting" class.
import java.applet.*;
import java.awt.event.*;
import java.awt.*;

public class ListenerTesting extends Applet implements MouseListener
{
    Panel panelOne;
    Label labelOne;


    public void init ()
    {
        setLayout (new GridLayout (3, 3));

        panelOne= new Panel ();


        panelOne.addMouseListener (this);
        
        labelOne=  new Label ("X");


        add (panelOne);

    } //init method


    public void mouseClicked (MouseEvent e)
    {
        if (e.getComponent () == panelOne)
            panelOne.add(labelOne);
    } //mouseClicked method


    public void mouseEntered (MouseEvent e)
    {
    } //mouseEntered method


    public void mouseExited (MouseEvent e)
    {
    } //mouseExited method


    public void mousePressed (MouseEvent e)
    {
    } //mousePressed method


    public void mouseReleased (MouseEvent e)
    {
    } //mouseReleased method


    public void paint (Graphics g)
    {
    } // paint method
} // ListenerTesting class

After a container is visible, you can't just add components to it and have it magically work. You have to revalidate the component after you add something to it. Check out the API for useful functions.
