help with JRadioButton Action listeners

linux_ub · 09-13-2004, 09:03 AM

Hi

i have a class which is being used to add a question followed by several choices like a multiple choice question. the choices are listed using JRadioButton.

Code:

	public Choices(String labelText, int noOfRB, String[] radioButtonText) {
		label = new JLabel(labelText);		
		group = new ButtonGroup();		
		panel = new JPanel();		
		panel.setLayout(new FlowLayout());		
		panel.add(label);		
		radioButtons = new JRadioButton[noOfRB];	
		for (int i=0; i<noOfRB; i++) {			
				radioButtons[i] = new JRadioButton(radioButtonText[i]);
				panel.add(radioButtons[i]);	
				group.add(radioButtons[i]);radioButtons[i].addActionListener(this);
		}
}

tha addActionListner piece of code gives me the following error
" the method addActionListener(ActionListener) in the type AbstractButton is not applicable for the arguments (Choices)

could any one please help my finding my mistake

thanks

Can't see any error right away, but I found this at Sun homepage:

http://java.sun.com/docs/books/tutor...ts/button.html

the only thing different that I can see, is that in this case, they have the amount of buttons defined from the beginning, but I doubt it has anything to do with your for >> next loop. Anyway, take a look into the example

Good luck!
