Now stuck with inserting data into a list.

[mainy]

Hi again!

I'm hoping one day that I won't actually need to keep asking for help on this forum but unfortunatly, I am stuck once again ><

I have two classes, which include two Jpanels. One of the Jpanels has a list in it, the other has a button. What I want to do, is when the person presses the button in one window, it adds some information to a list in the second window.

Rather than posting all the code I am just going to post all the relevent information. Here is the actionListener that detects the button has been pressed:

 
private void buttonActionPerformed(java.awt.event.ActionEvent evt) {                                         
        if (button.getActionCommand().equals("Yes")){
            chosenList cl = new chosenList();

            cl.addList("Yes");
 
            }
    }

This sends the string "Yes" to this method in the other class which contains the List.:

public void addList(String name) {
        list.add(name);
        System.out.println(name);
    }

I know that addList is recieving "Yes" as using the sout command it prints it out in the runtime window everytime I press the button. The problem is, for some reason it is not adding the String to the list. I have even tried going direct by putting inside the actionListener cl.list("Yes"); but with no luck.

If it helps, I think it has something to do with the list not being currently in Focus. I have tried such code as list.requestFocusInWindow(); without much luck either.

I think you should try to put this line

chosenList cl = new chosenList();

before the if statement. The cl object's scope is inside the if statement. Outside the if statement you have no cl object.

Give it a try!
