Hi all. I've been tasked with creating a smooth scroll on a long composite datawindow. The powers that be don't care for the row by row type scrolling, as some detail rows are much taller than others.

Anyway, I've created an event and associated pbm_vscroll to it, and I can get smooth scrolling to work with some code I found online:

if (scrollcode = 2) or (scrollcode = 3) then
    this.setredraw (false) // Comment this line if You want to see "jumps"
    this.post event ue_post_scroll (scrollcode)
elseif (scrollcode = 5) then
    this.mscroll = scrollpos
end if

However, with this implemented, clicking on the bar itself or on the arrows no longer works. I can't seem to find a reference for what the different scrollcode values mean, or what to expect with scrollpos.

Does anyone have a decent reference for how pbm_vscroll works?

Thanks!
