JComboBox is driving me crazy!! Help,please??

Question

Hello!!
The problem is that i have to get the MouseEvents whenever a user enters or exits or clicks mouse on an item inside JComboBox.
Is there anyway to get the mouseEvents? I ve tried adding a lot of listeners but nothing works.
Thanks a lot!

Try this.
When you click on the comboBox, the label is updated.
Hope this help.

* listener for the comboBox
class ListDemo_jComboBox1_actionAdapter implements java.awt.event.ActionListener {
