Jlist help

[liftthis]

I have created 3 files: SmsInbox, SmsGetData and SmsMsg.

I don't know if I set this up right. I want Phonenumber, message and time to be stored in the Jlist and when I double click it It will print out the phonenumber, message and time.

How do I print it out?

I would appreciate any assistance on how to get this to work. I comment the code in the mouse listener.

another thing, Does this need to be a vector. How do convert this to a vector object?

I have seen that example but I only want to display a list of incoming string phonenumber and when I double click on the phonenumber I will can print the message contents: phonenumber, message and time.

How do I do that?

> I only want to display a list of incoming string phonenumber
JList will display the toString() result of objects in the model, so you can override toString() in your SmsMsg class to display the phone number.

As for double-clicking, you can retrieve the currently selected item with list.getSelectedValue() and cast that to SmsMsg to do anything you want with the object (ie print data from it)

[liftthis]

I found a good example:
http://www.javadocexamples.com/java_source/__/jl/JListDemo3C.java.html

In this example the Jlist displays the object, how to you display something else, in the example above display the students name.

[Ezzaral]

I already told you above - override toString() in your SmsMsg class to display the phone number.

This is what you are talking about:

I already told you above - override toString() in your SmsMsg class to display the phone number.

[Ezzaral]

Yes. The JList will display the string representation of the objects by calling their toString() method. If you customize that, you can display any string that you wish.
