I have Java application which adds JTextFields @ runtime to JPanel. Basically user clicks a button and new JTextField is added, clicks again added again...
Each new JTextField is directly below the previous one. Obviously I run out of space pretty soon so I'm trying to use JScrollPane and thats where the hell begins, because it just doesnt work no matter what I try.
Code for adding new JTextFields is like this, in a case it's relevant.
JTextField newField = new JTextField( columns );
Rectangle coordinates = previousTextField.getBounds();
newField.setBounds(coordinates.x , coordinates.y + 50, coordinates.width, coordinates.height);
JPanel.add(newField);
JPanel.revalidate();
JPanel.repaint();
Sorry for a long post I'm just trying to provide as much info as possible, because being newbie I dont know whats exactly relevant and whats not. Thanks in advance :)
As there is another answer now, I'm adding my suggestion too.
This sounds exactly like a problem to use a JTable
with a single column. JList
is not yet editable (and might never be).
JTable
would handle the layout problems for you, and you can easily access the values via the table.
Use your own TableModel
(a simple Vector
should be sufficient in your case), and add values to it.
