I’m having trouble getting access to the scroll bars on the pdf viewer component, java noob here. I was able to control the rotation and zoom mode with the swingController ,`target.getController()`, but I don’t see anything with the scroll bars. Will those be apart of JScrollPane or something else?

**Update** I was able to get to the value of the scroll bar with

```auto
target = event.source.parent.getComponent('PDF Viewer')
swingController = target.getController()
viewController = swingController.getDocumentViewController()
hScroll = viewController.getHorizontalScrollBar()
print hScroll.getValue()

```

Wow, impressed myself a little bit 🙂 I figured it out.

```auto
target = event.source.parent.getComponent('PDF Viewer')
swingController = target.getController()
viewController = swingController.getDocumentViewController()
hScroll = viewController.getHorizontalScrollBar()
rightJustify = hScroll.getMaximum()
hScroll.setValue(rightJustify)
swingController.updateDocumentView()

```
