| Subject | JList: Scroll to Selected |
| Message-ID | <3ONmj.5795$O9.926@trnddc01> |
To: comp.lang.java.gui I'm using Java 1.4.2 and I've tried searching for this and can't find it, but I'm sure I saw a method for a JList to scroll to the selected item. There are times a JList (in a JScrollPane) is reloaded. On some platforms, apparently, when I reload it, even though I make sure the same item stays selected, users report that the list then resets to show the top of the list only. Maybe I'm mixing things up, but I was sure I saw something like scrollToSelected() for a JList or JScrollPane, but I can't find it in the API index and couldn't find it in a search. Is it under a different wording or is there another method that scrolls a JList to show the selected item? Thanks!

See JList.ensureIndexIsVisible() and JList.setSelectedValue()

I knew about setSelectedValue(), but the ensureIndexIsVisible() is exactly what I was looking for! I guess it's a case of tunnel vision where I was so stuck on what I thought I saw I missed what I needed. Thanks!
