Jlist.setListData()

Question

Hi everyone!
I use a Jlist to display the contents of a vector,in which items are added and removed in run-time. I use the function:
myList.setListData(myVector);
but sometimes it works just fine, sometimes myList displays nothing and sometimes the list diaplays its old contents! I used myList.revalidate() before and after changing the list, i also revalidate the JScrollPane that the list is in, but occasionally this happens.
Does anybody had the same problem or knows how to fix this? Am i using the function setListData() correctly or do i need to do something else when altering the Vector?
I am new to java, so any help will be appreciated...

Answer 1

well, in many part of my code i use the same method. and it works well all the time.
I'm not quite sure to know how to explain your problem but maybe it is because you do something like:
JList jl = new JList();
jl.setListData(vector);
//removal
vector.removeElement(Object o);
jl.revalidate();
}when you should code:
JList jl = new JList(vector);
//removal
vector.removeElement(Object o);
jl.setListData(vector);
jl.revalidate();
