Thread: about GUI stuff

My question is why doesn't my program work, and by that I mean : (when I click that check box it makes text bold), when I do this in my Study constructor : JCheckBox cb = new JCheckBox("bold"), but when I do it like the example below it works. Please answer, I'm dying to know.Thanks


public class Study extends JFrame {

private JCheckBox cb;
private JTextField tf;

public Study () {

cb = new JCheckBox("bold");
tf = new JTextField(25);


and later on some more code..



}

I don't see any code where you make your text bold on clicking the JCheckBox, and I don't see enough information to be able to hazard a guess why your code isn't working. Have you gone through the check box tutorial yet? If so, can you show us your ItemListener code?

Then if still stuck, consider creating and posting an SSCCE that demonstrates your problem.

rest of code is working, just like my program. but it didn't work when I did this in my constructor : JCheckBox cb = new JCheckBox("bold");
but when I removed that JCheckBox at the begining, so : cb = new JCheckBox("bold") it worked. can you tell me why ?

I cannot guess what may be wrong based on what you've posted so far. You probably have to tell us more and show us more, but before posting more code, please read the forum FAQ to see how to use code tags so that we'll be able to read and understand your code. Good luck.

you must import (javax.swing.JFrame) first

no i didnt read post #3....you are right
