I created a List box. When I add more items than will fit in the display size a vertical scroll bar is created. How can I cause a horizonal scroll bar to be created so that I can view lines that are too long for the display?

AWT or Swing?

I assume you are talking about common list of AWT. You may not treat it as an answer: you don't need to do anything, but the scroll bar will appear when it is needed.

You can make an applet and try two things:
1. Create a list and add items that are too long before execution, then execute the applet.

2. Create a list, a textbox and a button. At run time, when the button is pressed, the text content is added to the list.

You will see that in both cases, the scroll bar appear automatically.
(Please tell me if you find a different result.)

I am using AWT. I assumed it would work as you described, but I added an item that was too long and no horizontal scroll bar appeared. One note, I am using reshape to set the size of the list box. That may have an affect on my result.

I have tried reshape(), but it is ok. Anyway, reshape is deprecated, use setbound instead.
Could you post your code here?

When I said it didn't create a horizonal scroll bar I was running on 1.2. When I ran on 1.1.2 it worked as expected.

I have checked the spec. of list for 1.2, but it seems to contain nothing about the auto-scroll. If you are interested, please read
