Thread: Refreshing a JTabbedPane?

Alright, yet another question. Below I have a sample of a JTabbedPane I've been working on.
Every time the user clicks the sword icon it counts up.
I used this code to make it update the count displayed when it detects its been clicked:
swordCount.setText("Sword Count: " + count);
So basically I'm lazy and want to know if there is a different way to refresh a tab?
I thought these might do the trick:
panel1.revalidate();
panel1.repaint();
and I've included them in the code below.
But alas they do nothing. I'm not really sure what they are suppose to do anyway.
Any suggestions?
Thanks.

For Testing.

//25.14 1039
import javax.swing.JFrame;
 
public class JTabbedPaneDemo
{
 
	public static void main(String[] args)
	{
 
		CCD tabbedPaneFrame = new CCD(null, "Dialog Frame", true);
		tabbedPaneFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
		tabbedPaneFrame.setSize(250, 200); // set frame size
		tabbedPaneFrame.setLocationRelativeTo(null);
		tabbedPaneFrame.setVisible(true); // display frame
 
	}// end main
 
}// end class JTabbedPaneDemo

int x  = 5;
int y = 2 * x;
System.out.println(y);
x = 10;
System.out.println(y);

The output of the above code is 10 & 10 not 10 & 20. Just because x is changed y is not automagically updated.

public JLabel swordCount = new JLabel("Sword Count: " + count, SwingConstants.CENTER);;

If I understand correctly you are expecting the same thing with your code. Just because the value of count changes it does not mean your JLabel will automagically be updated too. If you want the JLabel to display something different then you must call the setText method.

I don't get it - you have to write the setText("..." + count) code whatever way you do it, but you only have to write it once - what has being lazy got to do with anything?

If you want the text to change, you have to change the text...
