I am doing the javaswing exercise, and I come across this type of parameter
passing a few times that I am getting very confused, I tried tying it back
to what I learnt from constructor chaining and overload, but I am still
lost, can someone enlighten me please.
Here is the snippet:
public class CelsiusConverter implements ActionListener {
...
JButton convertTemp;
...
private void addWidgets() {
//Create widgets.
...
convertTemp = new JButton("Convert");
//Listen to events from the Convert button.
convertTemp.addActionListener(this);
...
How does "this" refer to convertTemp which I know is an instance of JButton?
Thanks
Norman.
