Hello Clemens It sounds very similar to the bug 4743225
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4743225 As far as I know there is no any good workaround for this problem, sorry alexp
Hello, This is both a question and (if its really a problem) maybe an idea for enhancement. I've a JComboBox which should update its values at the time it is opened (because the come from a source which changes from time to time during the life of the JComboBox and I don't want to update it periodically). What I did was to register a PopupListener and changed the item of the ComboBox but the problem was that the Popup already existed - and although its values were updated its size was not. If I e.g. had 1 entry before the update and 4 afterwards I got a list with the size of 1 entry with very small scrollbars. The root of the problem seems to be that there is no legal way to access the BasicComboPopup (or whatever its called), as far as I've seen. Could my stuff be done in another way which would not cause the problems mentioned above? I currently did a hack which calls showPopup/hidePopup in the listener so that the too small list is hidden and afterwards the larger list appears but thats really a hack. I wonder wether it would be ok to work on that stuff so that the list re-calculates its size also when items are removed/added when the popup is already visible? Do you think that could break something? Please feel free to send commend, I would be really happy about suggestions. lg Clemens
