如何在linux中使用python检测当前鼠标cursor类型？

Question

What I'd like to do is find out the type of cursor (ie. pointer, normal, insert) currently active in Linux using python.

I've found one post mentioning that for windows using win32gui : The way to detect the current mouse cursor type from bash or python

win32gui is Windows-specific and this library will not work in Linux. Any other solutions?

Answer 1

Update: I have come up with three solutions, but they are rather effort and resource-intensive. And I haven't tested them out, so I don't know about any roadblocks. So at this point, I would still appreciate alternative solutions to this problem.

(1) You could find out the location of the mouse pointer using pyautogui and then take a snapshot of the pointer. Then you could compare this image with a test image of a cursor and calculate how similar both images look like using OpenCV .

(2) Run win32gui via Wine like service and send cursor data to linux application.

(3) Use python's ctype module to call XFixes C library's X FixesGetCursorImage(display) function.

Answer 2

Use this library PyXCursor to get the image of cursor/mouse-pointer for an arbitrary application window in Linux - in Python using ctypes
