JAVA: eliminate item from combobox ???

[angelica]

Hey,

I having these 5 comboboxes. On selecting comboxox1 I need to eliminate the same item from the other 4 remaining comboboxes, so that it wont be possible to choose the same item more than once.Yet the 5 comboboxes are distinct and cannot be put into one combo.

Hey any code or ideas are very much appreciated. Thanks loads

Which part are you having trouble with? To check when the selection was changed in a combo you need to implement an ItemListener like this :

class MyItemListener implements ItemListener {
	Panel cp;
	Choice c;
	public MyItemListener(Choice c, Panel cp) {
		this.cp = cp;
		this.c = c;
    }
    public void itemStateChanged(ItemEvent e) {
		if (e.getStateChange() == ItemEvent.SELECTED){
                        //do stuff here depending on the selection, change the items in the other combos
                        //CardLayout LM=(CardLayout)cp.getLayout();
                       
			//LM.show(cp,(String)e.getItem());
		}
	}
}

And in your main code :

		c.addItemListener(new MyItemListener(c,cards));

surely that is pretty easy, write a wrapper that takes in two combo boxes, n and n + 1
add change listeners to n, then when there is a change you know which item to remove from n+ 1..

where is the hardship?!
