如何使用左侧的JTextArea自动滚动JScrollPane

Question

I have private JTextArea opisDiagnoza; I insert it into JScrollPane jsp , like this:

opisDiagnoza = new JTextArea("Opis diagnozy:\n");
        JScrollPane jsp = new JScrollPane(opisDiagnoza, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);

Later on, when I do:

opisDiagnoza.setText(REALLY_LONG_TEXT);

the JScrollPane autorscrolls to right, so to read the content I need to manually(by clicking horizontal scrollbar) scroll it to the left.

How to autoscroll JScrollPane to the left after inserting a text into JTextArea inside of it?

Try this

DefaultCaret caret = (DefaultCaret)textArea.getCaret();
caret.setUpdatePolicy(DefaultCaret.ALWAYS_UPDATE);
