How to diable JDialog on refresh of a data in a tab

Question

Hi,
I have an application which has a tab1 which contains a Jtable.On clicking a cell in Jtable a JDialog appears showing some more info on the cell clicked.
Now i want to do this...
When i refresh the tab1 the corresponding Jdialog should become empty without any value, assuming that tab1 content has changed.
How i can go about doing the above?
A simple code snippet/idea would be of great help.
Thanks.
