Dear all, I'm using several IupMatrix (more than 10, can be up to 20) in my musical application (on Linux, mint 20), and those matrixes can have a lot of lines. I noticed that scrolling is a bit slow when I scroll with mouse wheel.And it's even worst when the scrolling is done programatically with the "ORIGIN" attribute. When I say slow, I mean it's more than a few milliseconds, which is a big deal in a musical software, where many graphic elements are redrawn at something like 30 frame per second. In some context, the matrixes "ORIGIN" attribute can be reset several times per second, which is slowing the other graphical elements. Is it related to the IupMatrix itself ? Is there a quicker way to scroll programatically? Is the "SHOW" attribute quicker ? And if so, I couldn't find a way to make it work.
Thank you ! Johann
