Problem with JDialog Box

[Neha D]

Hi,

I have a JDialogBox which is displayed for two different actions.
When i double click on a table cell this dialog box is diplayed & also when i right click on the tabl cell this dialog gets displayed.

When it gets displayed for a double click all the components of that dialog are to be made visible. But when it gets displayed for a right click, one of the component (a panel on that dialog) should not be displayed & the space occupied by that component should be used evenly by other components.

Can anybody plz help me out with this problem.

Help is heartedly appreciated.

Thanx.
Regards,
Neha
