在ubuntu 20.04 LTS上使用python Xlib或CAPI操作第二个（辅助）鼠标输入

Question

我正在使用ubuntu 20.04 LTS，2个计算机鼠标（Microsoft Microsoft® 2.4GHz Transceiver v9.0 Mouse, id=11和MX Vertical Mouse, id=31）连接到2个不同的主机（Virtual core pointer, id=2和Auxiliary pointer id=27），请参见xinput：

问题:

如何使用python操作附加到{}（而不是{}）的{}，例如使用{}、pyautogui.moveTo、xaut等，或者直接使用{}的{}-API

问题:

这些基于Xlib的python包中的任何一个都只控制带有附加的Microsoft Microsoft® 2.4GHz Transceiver v9.0 Mouse, id=11从机的Virtual core pointer-master。所有包都通过将Xlib.display.Display()传递给Xlib.ext.xtest.fake_input()函数来获得初始的Virtual core pointer-master，该函数不接受任何进一步的输入来指定应该操作哪个指针（…但不确定最后一点）。我可以用例如Xlib.ext.xinput.query_device(window, xinput.AllMasterDevices).devices[1]来获得Auxiliary pointer-master，但是我不知道在哪里插入它。同样，使用Auxiliary pointer的源id id=31也没有帮助

我很感谢任何建议、想法或解决方案，提前谢谢

Answer 1

X11/extensions/XInput2.h::XIWarpPointer移动由deviceid指定的设备指针

XIWarpPointer可用于控制由鼠标/光标所连接的主指针id（而不是鼠标的设备id）定义的鼠标光标：

#include <X11/extensions/XInput2.h>

Bool XIWarpPointer( Display *display,
int deviceid,
Window src_w,
Window dest_w,
double src_x,
double src_y,
int src_width,
int src_height,
double dest_x,
double dest_y);

下面是一个如何将其集成到C中或构建一个库，然后使用例如CFFI与python接口的示例：
