GUI TextField issues

[patman]

Hey, Im working through a project right now and im struggling with getting the text from the text field. Here is part of my code

	public Input(){
		Fun = new JTextField("Function", 12);
		Var = new JTextField("Variable", 12);
		Start = new JTextField("Start", 12);
		End = new JTextField("End", 12);
		ActionListener buttonListener = new ButtonListener();
		JButton button = new JButton("Graph");
		button.addActionListener(buttonListener);
		TPanel = new JPanel(null);
		TPanel.setLayout(new GridLayout(1, 5));
		TPanel.add(Fun);
		TPanel.add(Var);
		TPanel.add(Start);
		TPanel.add(End);
		TPanel.add(button);
                add(TPanel);
	}
	
}
class ButtonListener implements ActionListener{
	
	public void actionPerformed(ActionEvent e) {
		Poly p = new Poly(Fun.getText());
	}
	
}

Poly is an object I created in another class. But i am getting an error with the Fun.getText() line. Im sure Im just doing this the wrong way so Im just looking for the right way to do it.
Thanks

Try putting your ButtonListener class into the same class as the Input() constructor. I think that this will do the trick.

Mint dude! I think that did it.

You can have the listener in a separate class, and often you'll want to do that, but it will need some way to call the methods of the GUI class, and so will need a reference to the GUI passed in to it, possibly via a constructor parameter.
