How can I tell if I'm at the bottom of a ScrollPanel()
Hi, I have an application where a user needs to read through the a document displayed in a ScrollPanel() and when they've scrolled all the way through I want to enable a button that the user can click on to acknowledge that they've read the document. How can I tell if the user has scrolled all the way through to the text (scroll bar all the way at the bottom). I can use getScrollPosition() to get the vertical scroll offset in pixels, but how can I tell what the max value should be should the documents content be changed?
