Reg Ren Matrix Update Time

Hi friends, It seems my scripts that change the region render matrix may be flawed - but I'm not sure. They are working as desired - but the Region Render Matrix Window GUI seems to take a while to update. IE I have a script that adds a region to the matrix at the cursor position for each track currently selected. It works as desired, but it takes two or so seconds for the Region Render Matrix GUI to update, coloring in those cells. Has anyone seen anything like that? Best, divedive

Lag like that is often just Reaper's graphics catching up because you've created a whole bunch of individual screen updates. i.e. Calling the "create new track" action 100 times will take a few seconds because it doesn't know you're creating 100 tracks and has to draw them one at a time. If that's the case, you can tell Reaper to wait while you do your stuff and then only have to redraw once: Code:

Lokasenna, Thank you again. I'm not sure that's fixing it. The below little script still takes a while to update the GUI. If I three tracks and three regions, and click a couple in the GUI to test - it takes a second or two to clear the region render matrix - and I don't imagine this method is so inefficient that it is the cause. Any thoughts? reaper.PreventUIRefresh(1) for h = 0, reaper.CountTracks(0)-1 do for i = 0, reaper.CountProjectMarkers(0) do retval, isRgn, startPos, endPos, name, markrgnindex = reaper.EnumProjectMarkers(i) if isRgn then reaper.SetRegionRenderMatrix(0, markrgnindex, reaper.GetTrack(0,h), -1) end end end reaper.PreventUIRefresh(-1)

Oh, you're running into a different issue. There isn't actually a time delay, it's just not updating the RRM window until you move the mouse over it. I've tried using reaper.UpdateArrange(), didn't help, and I also tried toggling the RRM window off and on but for some reason it doesn't bring it back up. I'd call it a bug.

Ah ok. Thanks again Loka.
