//some code
Vector datalist = new Vector();
String fname=f.getName();
for(int i=0;(i<datalist.size());i++)
datalist.add(fname);
jlist.setListData(datalist);
System.out.println(datalist);
it is showing all names in dos prompt through System.out.println()..
but not through jlist.
Any help please

I'm having a problem with JList (it's not showing the
elements added to the List).
i've checked the forum, but couldn't found the answer
to my problem. Any suggestion on the forum search
keyword?
here's my code
public class TestClass extends JFrame{
public static void main(String args[]){
JFrame fra = new MyClass();
fra.show();
public class MyClass{
private JList list;
public MyClass(){
setSize(400,300);  
list = new JList();
JSplitPane split = new
ew JSplitPane(JSplitPane.HORIZONTAL_SPLIT,
new JScrollPane(tree),
new JScrollPane(fileList));
ContentPane c = getContentPane(c);
c.add(split);
} // end of constructor
public populateListAtRunTime(){
DefaultListModel listModel = new
ew DefaultListModel();
listModel.addElement("Testing 1");
listModel.addElement("Testing 2");
list = new JList(listModel);/*^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
With this line you are not changing the
list you have already added to the SplitPane
(I think it is already added before this gets
called, you never show the relationship of this
method to the constructor...), instead, you are
creating a new JList which you never add to
anywhere. Is there a way to instead add elements
to the JList's data model instead of creating a new
one? Something like this:
DefaultTableModel listModel = list.getListModel(); //Or something like it...
listModel.addElement(//...);
list.revalidate();
} // end of myClass (inner class)
The tree showed up in the split pane
And i think the list also showed up on the splitpane
also (except that the element value is not
there)...any clue on why this is happening?
sorry again..i know this topic must have been posted
numerous time, but i'm bad with search term
keyword..and did not find any result that come close
to my match
I tried JList + visible, JList + show, and a few
other
