    Post JButton event handler

    am using an image button in my swing program...
    but i didnt kno how to exactly identify the button clickd by the user..
    wen i use getSource() method am receiving exception...

    If it is a norml button we'll be checking the button text...If it is a image button without any text what shud be checked to determine the button clicked..? am confused...!

    Default Re: JButton event handler

    You can check the actual instance of the JButton against the source simply using ==.

    Or you could only add that ActionListener to that JButton, eliminating the need to check the source.
