问题 I have an event handling code that reads Linux's /dev/input/ for my touchpad and prints result on the basis of which button is pressed/released. Although. as of now my code is waiting on a button press while running on terminal. My next step is to run this event handling thread along with another thread (not event based). If I continue handling event by reading input at terminal, I will not be able to execute other threads as a part of my main() as main() keeps on waiting for the button press

问题 so I'm trying to build a short script in Python. What I want to do is that if the mouse is clicked, the mouse will reset to some arbitrary position (right now the middle of the screen). I'd like this to run in the background, so it could work in in the OS (most likely Chrome, or some web browser). I'd also like it so that a user could hold down a certain button (say ctrl) and they could click away and not have the position reset. This way they could close the script without frustration. I'm

问题 I'm using Python and OpenCV for some vision application. I need to save mouse position in variables and I don't know how. I can get the current mouse position to print in window, but can't save it to variable. My problem is similar to this one only I work in python: OpenCV Return value from mouse callback function I define my function like this (for printing mouse position): def mousePosition(event,x,y,flags,param): if event == cv2.EVENT_MOUSEMOVE: print x,y I use it in my program like this:
