    Default Disabling Check Boxes created by different method.

    So. I have the following method that is called to create Check Boxes:

    	//function to create check boxes and add them to frame ( complete with action listeners )
    	public void addCheckButton(int i){
    		String ButtonNum = Integer.toString(i);
    		JCheckBox select = new JCheckBox(ButtonNum);
    		select.setBackground(new Color(56,48,44));
    		select.setForeground(new Color(225,255,255));
     
    		con.add(select);
    		select.addActionListener(this);	
    	}

    I am creating these buttons in my implemention like so:

    		//add our check-buttons
    		for (int i=0; i<35; i++){
    			lottery.addCheckButton((i+1));
    		}


    I want to disable all of my created checkboxes when 6 are selected. I am using the action listener event like so:

    	public void actionPerformed(ActionEvent evt)  { 	
     
    			//String Action= evt.paramString();
    			this.check_six++;
    			if (this.check_six<=6){ 
    				JOptionPane.showMessageDialog(frame, "Action id: " + check_six);
    			}
                else {
                	JOptionPane.showMessageDialog(frame, "MAX");
                	//DISABLE CHECK BUTTONS HERE!
                }
     
           }


    Does any one have a solution for this that would work with my current setup?
    thx

    You have to keep a reference to the checkboxes you want to disable, then iterate over them and disable them when appropriate.

    I see. So would this pretty much require me making a class scope variable?

    That's one way to do it. Or you could pass the reference around as a parameter to the necessary method(s).
