Dispose a JDialog after a certain time

Hi all,

I have a JDialog with a button. Button implement to dispose the dialog by a click event. Say user not click the button within 1 minute to dispose, in such case I want to automatically dispose it. How can I do that.

I know this is going to be work about thread. But I'm not much familiar with them.

Ok, I've solved the question my self. Put into to sleep for a specified time and dispose. That sleep not freeze any other controls as well.

Do you guys think it's a safer way?
