Dialog title to depend on tab name dynamically....

Question

Hi,
I have an application which has a tab(Phones) and tab has a Jtable with some data.
When i press Lookup button the first tab-Jtable loads .
When i right click on a cell in the table, the corresponding row first coloumn value is shown through a dialog.
Now in the dialog the title is "Shakin", i want the dialog title to be dynamic depending on the tab(name) it is clicked i.e it depends on the tab names (like in this case Phones).
If someone click a cell in table of first tab(Phones) then the dialog title should also be Phones.
In future if i add more tabs then each tab would have dialog and each dialog title would depend on each corresponding tab name.
Can somebody suggest be what to do?
Below is the code....

Use a ChangeListener, it fires every time a new tab is selected.
