Using ActionListener to determine value in JComboBox

[Ben]

Hi, can anyone help with this?

At the moment I have a class that implements ActionListener and
overides the method actionPerformed (ActionEvent e).
I have a number of JButtons that have the custom listener
added to them using addActionListener(customListener). In order to
find out which button was pressed I attach an action command to them
using setActionCommand("text"). I then use getActionCommand() in the
custom listener class to find out which button was pressed. This works
great for buttons. But I have a JComboBox that contains a number of
values. How can I do a similar thing and find out what value was
selected in the combobox from the listener?

Thanks in advance for any help.

Ben.

Don't worry I got it I used getSource and cast it to a JComboBox.

Actually thinking again is there any way to use ActionEvent.getSouce()
and distinguish if a JButton or JComboBox were used and then which
button and what value in combobox without using setActionCommand?

Thanks.

Ben.

It sounds like you're looking for the instanceof operator.

Yes, source instanceof JComboBox for example.

But, what if you will have more than one JComboBox?

If you started mark your buttons by setActionCommand(String)
you may continue it with JComboBox too.
Or you may set to any Component name as identifier
