Cursor Position or Text Position

Hello everybody in Expert.

I have a jList, and when i select one item, i want it to be showed in a JTextField... no problem with that...

The problem is that when the length of text in the Jlist is bigger than the length of the JtextField that is visible, then it shows the end of the text...

I know it is not very clear... maybe i can make it clearer with a diagram:

Imagine this is the Jlist:

-------------------------------------------------
| Text of first item of the List                |
| Text of second item of the List           |
| Another text of an item of the List     |
| Text of 4 item of the List                    |
|                                                           |
-------------------------------------------------

And this is the JtextField:

----------------------
|                          |
----------------------

Then when i make a click on one item (for example the second), i show it on the JtextField. But it appears like this:

----------------------
|d item of the List|
----------------------

Instead of like i would like to: (i would like to see the first part)

----------------------
|Text of second it|
----------------------

Anybody could help me??

Thank you a lot.
