To make the JScrollPane start scrolling at the top, you can use the setViewportView() method on the JScrollPane to set the view position to the top. Here's an example code snippet:

JScrollPane scrollPane = new JScrollPane();
JPanel panel = new JPanel();

// Add components to panel

scrollPane.setViewportView(panel);

// Set view position to top
SwingUtilities.invokeLater(() -> {
    scrollPane.getViewport().setViewPosition(new Point(0, 0));
});

By using SwingUtilities.invokeLater(), we ensure that the code is executed after all pending events have been processed. This way, we guarantee that the view position is set after everything has been laid out correctly.

Another option is to use scrollRectToVisible() on a component within the JScrollPane that you want to focus on. For example:

Component component = // get component you want to focus on
component.scrollRectToVisible(component.getBounds());

This will scroll the specified component into view at the top of the JScrollPane.

By setting the view position or using scrollRectToVisible(), you can ensure that your JScrollPane starts scrolling from the top.
