I'm handling mouse events in jit.window using the mouse and mouseidle messages. I need to handle double-clicks. Is there any handy way to get jit.window to report a double click, or do I have to re-write standard OS double-click recognition into my Max patch?

i dont know if theres some build-in parameter in jit.window for this, but in the meantime you can do something like this to catch them...

That is basically what I had in mind for Plan B. To do it for a production project one also needs to check that the mouse coords are the same (or "close enough" -- I think within +/- 4 pixels in either direction) and the time threshold ought to look up the user's OS-level double-click time threshold (as set in Mouse System Preferences on Mac, Mouse Control Panel on Windows). Offhand I'm not sure there's a way to do the latter with standard Max objects, or even with js or java. I can do that in C, but if I can find an incantation to get jit.window to do the lifting I'd be happier.

with an if object you can check that position of X and Y mouse coords is between a given bounds.. btw the other day i found this:

and yes, this two click solution is independent from the computer OS mouse settings... but you can tweak the [< 100] object, maybe 100ms is too fast...

I wasn't worried about how to use an [if] object for proximity detection (been doing that for over twenty years) but I *am* worried about how much slop MacOS and Windows UIs allow in double-click detection. It's documented somewhere, but it's always in the last place you look.

Similarly, you're correct that 100ms is too short. I understand the default dblclicktime on Windows is 500ms. But it is user-configurable on both Mac&Windows, and it seems I will have to write and external object to politely ask the OS just what the user configuration is. Yes, of course I know how to write an external. But it's a lot of time I don't want to have to invest if there is a message to jit.window tucked away somewhere that would to the job. Which was the original question and the answer is apparently 'no'.-(

The point is that I'm developing production code. If I have to re-implement double-click recognition, I have to replicate OS behavior 

. Sorta-maybe-kinda-close-almost doesn't cut it.

I know that [jsui] handles doubleclicks with

don't know if 1) jsui is getting doubleclick info from the OS, or 2) whether you can use this somehow in your case, as you're interested in jit.window. But maybe there's a js workaround somehow.

Tried [jsui] but performance went down the tubes very fast. That's why I'm with jit.gl.sketch/jit.gl.render/jit.window now. Of course, it would be nice if jit.window did double-clicks like jsui. That's why I asked.

Is [jsui] getting double-click events from the OS? It would seem daft not to, but no knowing.
