Hi,
for some reason, my JScrollPane isn't working with mt JTextArea.
Probably the most important part:

JTextArea TextArea;
JScrollPane scroll;
TextArea = new JTextArea();
scroll = new JScrollPane(TextArea);
add(TextArea,BorderLayout.CENTER);
add(scroll,BorderLayout.LINE_START);

Whole code if you're interested in what I'm making:

Thanks.

I would omit the line:
add(TextArea,BorderLayout.CENTER)

Since you created the scroll with the TextArea as argument, you might want to add only the scroll:
add(scroll,BorderLayout.LINE_START)
Because the scroll already has the TextArea.

You can try that for starters.

P.S. It might, in the future, help to describe "don't work" precisely, as that is the singularly most useless problem description in the world.
