macOS Scrollbar handler

[printf]

i'm creating a scrollbar at runtime using the following:

CreateScrollBarControl(window,&sb_vert_rect,0,0,100,50,true,ScrollingFeedbackProc,&sb);

how do i capture scroll events in the handler for the window this control was created in? i've tried kEventClassControl, kEventControlClick with InstallControlEventHandler just to capture a click, but it only captures clicks in the window, not the scrollbar control.

also, i'm using a compositing window with hiview.

Here is some code that may help: Creating a Scroll View. It uses the HIScrollViewCreate() function with subviews instead.
