Accessing a JTextArea in a JScrollPane

I have a JTextArea in (multiple) JScrollPane in a JTabbedPane.

I need to access the JTextArea. If I didn't have the JScrollPane, I could do:

JTextArea c = (JTextArea)jTabbedPane1.getComponentAt(i);

How would I get it when in a JScrollPane?

Cheers, Gazler.

Solution

  • This line looks complex, but I THINK this would do it.

    JTextArea c = (JTextArea) (((JViewportView) (((JScrollPane) jTabbedPane1.getComponentAt(i)).getViewport()))).getView();

    But I think it would be more interesting to store your TextArea's in an ArrayList.
    So you can do this:

    List<JTextArea> listAreas = new ArrayList<JTextArea>();

...
JTextArea c = listAreas.get(i);

    Create a new one is something like this:

    JTextArea c = new JTextArea();
jTabbedPane1.addTab("Title", new JScrollPane(c));
listAreas.add(c);

    Hope this helps.
