Displaying ArrayList in JScrollPane & Panel 1

[asiavoices]

Hello all,

I have another question that I'd like to try and code, learn and to see if this was possible....

How can I display my recordset, created from an ArrayList into a JPanel I've created? I'd like to have the people be ale to scroll through the list if possible.

For eample, I'm thinking of putting the recordset into the JScrollPane and then putting it into the Panel.

=========================
= My list =
=========================
= =
= item1 cost taxID =
= item2 cost taxID =
= ............ =
= =
= =
=========================

The list is inside a JScrollPane.

How do I go about doing that? I know you can put a Vector into a JScrollPane but "not " an ArrayList.

Any ideas?

Thanks,

Christopher

You much better off going with a Jtable or a JList as suggested by pipk, inside a JScrollPane. As a correction, there is no way to "put a Vector into a JScrollPane". That statement infers that there is some method in JScrollPane that accepts a Vector for display, this is not the case. Regardless, it would be very easy to create a Vector out of an ArrayList if that is what was required.

Hello wushutwist ,

Thank you. How does one "create" a Vector from an ArrayList?

Thanks,

The Vector class has a constructor that accepts a Collection objects to place in the Vector. Since ArrayList is of type Collection, it then becomes trivial. Example:

ArrayList al = new ArrayList();
al.add(new Integer(1));
Vector vec = new Vector(al);
System.out.println(vec);

Here are the Javadocs for the Overloaded Vector Constructor:

Vector

public Vector(Collection c)

Constructs a vector containing the elements of the specified collection, in the order they are returned by the collection's iterator.

Parameters:

c - the collection whose elements are to be placed into this vector.

Since: 

1.2
