I need a way to refer scrollbar or to know its rect

Hi, guys:

I need a way to know when the mouse is over the scrollbar on a scrollview. I have scripted a zoom button and a drag system on the whole GUI layer. Now the problem is when i try to drag the scroll bar, the entire GUI drags. So i need to know when the mouse is over the scrollbar. Remember i’m using scrollview. If i knew the rect of the scrollbar i could use rect.Contains, but the only rect i know is the window’s rect defined in the scrollview.

TYIA.

Well, this question is pretty well answered here: Is there a way to scroll GUI text WITHOUT scrollbars? - Unity Answers
