How to set the initial position of a vertical scrollbar in a JScrollPane?

[Yingie Pitts]

Below is how I created a JScrollPane.
...
JTextArea reasonText = new JTextArea();
reasonText.setText(....)
JSrollPane reasonScroller = new JScrollPane(reasonText, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
...
After I run the program, the position of the vertical scroller is always at the end of the textarea. But I want it to be at the begining of the textarea. Does anyone know how to do it?
Any insights would be appreciated.

reasonScroller.getVerticalScrollBar().setValue(reasonScroller.getVerticalScrollBar().getMinimum())
or with aptly named variables:
JScrollBar scrollbar = reasonScroller.getVerticalScrollBar();
int min = scrollbar.getMinimum();
scrollbar.setValue(min)

Thanks, Jon. It is a very correct way to position the scrollbar, however it did not work for me. I tried to change the JTextArea to TextArea then the scrollbar was shown at the beginning. But I don't want to use TextArea here.
Are there any other ways to handle a scrollbar's position in a JScrollPane?

Hi,
You could try...

JTextArea reasonText = new JTextArea();
reasonText.setText(....)
JSrollPane reasonScroller = new JScrollPane(reasonText, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); 
// Bring the caret to the beginning of the text.
[B]reasonText.setCaretPosition(0);[/B]

Hope this helps,
Abhik.

If your problem is to make Ist line of JTextArea visible, try any of the following.
1) textArea.setSelectionStart(0);
textArea.setSelectionEnd(0);
2) textArea.setText("...");
textArea.requestFocus();
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_HOME);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyRelease(KeyEvent.VK_HOME);

setCaretPosition(0) or textArea.requestFocus() both works.
Thanks everyone.
