Should be really simple, how do I make a jbutton show a jframe i have already created via the window builder in eclipse?

Question

Not sure if I'm just using a visual basic approach, but I was under the impression i could use the window builder in eclipse to create my Jframes, then simply invoke them when the button/actionlistener is selected...

Like:

JButton btn_register = new JButton("Register");
        btn_register.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
                frm_register.setvisible(true);

            }

frm_register is the class name for the register form...

What's the problem when you tried this? Are there compiler errors? Runtime errors? — copeg, May 27 '15 at 18:00
You need to create a frm_register first: `frm_register myFrame = new frm_register` — ControlAltDel, May 27 '15 at 18:03
I just had no idea how to approach this, Thanks Nicola, that worked a treat. — Reece Mathieson, May 27 '15 at 18:05
@ReeceMathieson, if the problem has been solved then don't forget to "accept" an answer so people know the problem has been solved. — camickr, May 27 '15 at 18:33

I hope not. Class names should start with upper case character. For example: RegistrationForm.

Then you need code like:

RegistrationForm  register = new RegistrationForm();
register.setVisible( true );

This of course assumes that the constructor for the RegistrationForm adds components to the form and does a pack on the form.

i could use the window builder in eclipse to create my Jframes,

Also, you should not be using a JFrame. An application generally has a single JFrame. A child window would typically be a JDialog. See: The Use of Multiple JFrames: Good or Bad Practice?
