如何在 python (Xlib) 中模拟键盘按键 我一直在使用 Xlib-python 来模拟鼠标指针事件,例如移动和点击。但是我无法找到足够的帮助来为键盘按键做类似的事情。
首选平台:linux上的python
为此使用xtest 。作为额外的奖励,它还处理指针事件注入。
我不是 Xlib 方面的专家,但我设法为 PyAutoGUI 模块拼凑了这段代码。这是可以模拟键盘键keyDown()
的最小可行示例:keyUp()
# You must run `pip3 install python3-xlib` to get the Xlib modules.
import os
from Xlib.display import Display
from Xlib import X
from Xlib.ext.xtest import fake_input
import Xlib.XK
_display = Display(os.environ['DISPLAY'])
# Create the keyboard mapping.

链接可能已损坏,这是我用来构建的类似 Python 代码块:
