[Qt-interest] MouseMove response time resolution

["Alexander Carôt"]

Hi all,

I just checked the mouseMoveEvent handler in terms of response time resolution. In that context it seems that it does not notice events, which occur within a time frame of approx. 15 ms.

What I did: I have a thread, which executes each 1.3 ms. Into this thread I plot the mouseX and mouseY coordinates (updated in the mouseMoveEvent according to event->globalX and event->globalY) while dragging the mouse quickly from a to b and so forth. With each execution I hoped to see the updated x and y coordinates for the respecive mouse position. However, it takes 12 circles to see a coordinate update, which makes me believe that the corresponding mouseMoveEvent is not updating in the desired time response resolution.

In this correct or is there a way how to improve the time resolution ?

Thanks in advance and best regards
