Question

In my GUI a have a JTextArea within a JScrollPane that is attached to a container.

        ta = new JTextArea();
        jsp = new JScrollPane(ta);

        container.add(jsp);

I want to be able to replace this JTextArea with another JTextArea, for example

JTextArea ta1 = new JTextArea("New text area");
ta = ta1;
ta.repaint();

However, when I reassign this JTextArea nothing in the GUI changes. Is there a better/correct way for doing this?

Answer 1

You should just replace text of textarea with new one.

newTextArea.setText(oldTextArea.getText())

or simply put new text by

newTextArea.setText("new text")
