Disabling scrolling of a JTextPane when document is updated

Hello,

I have the following problem, that I try to resolve unsuccessfully
for some time:

I have a JTextPane in a JScrollPane. When I use setText() to update
the text in, the JTextPane gets scrolled to the end (last line).
I'm trying to suppress this - what I need is to have the scroll
bar remaining in the same state as before.

I tried removing all listeners that I could come up with (for example,
the CaretListener), tried extending JTextPane and overwriting the
fireCaretUpdate() method with an empty one - none of this worked.

Any ideas?

Thanks,

- Alex

if you want to keep scroll in its position
then remeber position, load text, call scrollBar setValue.
setValue should be called from EventQueue
// --- load text --

EventQueue.invokeLater(new Runnable() {
public void run() {
scroll.getVerticalScrollBar().setValue(pos);
}
});
