i modified the mouseup plugin, now you get the coordinates from mouseup mousedown and motion.mouse_coordinates_plugin.zip

any idea how to modify the plugin or the patch to specify a pd window or a canvas where i get the coordinates from? at the moment i get the coordinates from the mouseposition in every pd window.

I have no real agenda here apart from wishlist, but surely a mouse up event would be a necessity in any programming language and is seriously missing in Pure Data.
So here I offer yet another clunky work around where line is giving an immediate update then the y output is forced into a matrix
slider-line.pd

You know that you can get mouseup from [iemguts/receivecanvas], right?
