Java add a jpanel in a jtabbed pane in a jframe from another class file

Question

I am lost, can you please help?

I am trying to add a jPanel from a another class into a different file into a JTabbedPane in JFrame file.

Here is what I have so far.

jPanel1 = new javax.swing.JPanel();

Answer 1

One party needs a reference to the other in some way, for example, in your "other" class, you could provide a getter method...

public class OtherClass ... {
    public JPanel getComponent() {
        //...
    }
}

Then in your main UI, you could use the instance of OtherClass to get a reference to the JPanel ...

tabbedPane.addTab("My Awesome Tab", instanceOfOtherClass.getComponent());

But this is all hypernethtical and is just one possible solution...
