Vertical scrollbar setValue always sets it to 90

I'm saving the state of two scrollbars and loading it with these two methods:

private void saveScrollPosition() {
    scrollY = scrollPane.getVerticalScrollBar().getValue();
    scrollX = scrollPane.getHorizontalScrollBar().getValue();
    System.out.println("Saved: " + scrollX + "," + scrollY);
}

private void loadScrollPosition() {
    scrollPane.getVerticalScrollBar().setValue(scrollY);
    scrollPane.getHorizontalScrollBar().setValue(scrollX);
    System.out.println("Should load: " + scrollX + "," + scrollY);
    System.out.println("Loaded: " + scrollPane.getHorizontalScrollBar().getValue() + "," + scrollPane.getVerticalScrollBar().getValue());
}

The horizontal scrollbar is doing what it is supposed to do but the vertical is always set to 90.

Console:
Saved: 185,882
Should load: 185,882
Loaded: 185,90

Found a tip in a forum to create a new Runnable method and start it with

SwingUtilities.invokeLater(doScroll);

but it didn't work out.

I wonder what I'm doing wrong...

Solution

  • I had to update my contentPane first. Then the vertical scrollbar got updated to the correct values. Idk why it worked with the horizontal scrollbar...

    Before:

    loadScrollPosition();  
contentPane.updateUI();

    After

    contentPane.updateUI();
loadScrollPosition();

    Hope this helps
