Hi,
   I am using
JLabel(String text, Icon icon, int horizontalAlignment)

to write code for a image browser.  Right now it displays thumb nail images with
file name on top.
I want to put a checkbox next to file name for user to
select or deselct the image. How can I extend the JLable
class so it not only take a icon, a text string, but
also a checkbox?

Thanks.

 Why do you need to extend JLabel? Can you not just add a check box next to the JLabel and enable/disable the thumbnail? If checkbox is enabled then call the J:Label's constructor that does not require an Icon sa parameter, if it is not enabled called the one that does.

  Hope it helps.

You could create your own class based on JPanel.

Inside this panel, put your existing label and the new checkbox.

add an event handler to the checkbox, and make the right calls into the label when things are checked.

then plug in this panel wherever you are using your label today.
