Hello.

In a nutshell, I want to be able to access the current location of the scrollbar in a scrollable uipanel. I know that I can set it by using the "scroll" function but not sure how to "get" it. I also assume this can be done by adding a scroll callback function but i dont think this is possible in a panel. would be thankful for any assistance. details follow in the first comment

Details: I am working on an app with several panels, with a drag and drop functionality. For example, if you drag on the right side of this panel it should do this and that, if you drag in the left side of this panel you should do this, etc.

the problem is that one of the panels is scrollable, and the location of the mouse is known relatively to the screen or window, not the panel itself. so now if I drag into a location on the scrollable panel I get wrong coordinates. this could be solved by subtracting the location of the scrollbar from my calculation but I don't know how to access it.
