click theRunIsStuck

[chenyuxingkong]

from pynput import mouse
from pynput.mouse import Button

isRun = False
ctr = pynput.mouse.Controller()


def g36k():
    global isRun
    isRun = True
    print("start")
    # 运行卡死
    # theRunIsStuck
    ctr.click(Button.left)
    print("end")


def on_click(x, y, button, pressed):
    print(f'鼠标按下: {button} at ({x}, {y})')
    global isRun
    # 鼠标松开时触发
    if not pressed:
        if button == Button.x1 and not isRun:
            # 将 g36k 的调用调度到事件循环
            g36k()
            isRun = False


if __name__ == '__main__':
    # 创建鼠标监听器
    listener = mouse.Listener(on_click=on_click)
    listener.start()
    listener.join()

The above is my py code. When I run to ctr.click(Button.left), I can't output print("end "), and my mouse is stuck.

Thank you for your report.

As you do not state what platform you are running this on I can only speculate. However, I think the issue is that these functions are not invoked sequentially; when a mouse button is clicked, on_click is eventually called and the check whether isRun is True is performed. Since it is not, g36k is called, a fake event is emitted and isRun is reset to False. Some time later, the fake event will cause on_click to be called again, but isRun has already been reset.

I suggest you check out the feature-injected branch. On that branch, you get an extra argument to on_click: injected. This argument signals that the current event was not generated by the user, but rather some other controller; this appears to be what you are after.

I would love some feedback on that branch; it has remained unmerged for six years already, but I have at least kept it up-to-date.

@moses-palmer thank you for keeping it up to date. I would like to use this in https://github.com/OpenAdaptAI/OpenAdapt (until now we are using #550).

However using the feature-injected branch on MacOS 14.2.1 Python 3.10.9 I am getting:

Unhandled exception in listener callback

NameError: name 'Quartz' is not defined

To fix:

https://github.com/moses-palmer/pynput/blob/feature-injected/lib/pynput/_util/darwin.py#L43 should have:

CGEventGetIntegerValueField,
kCGEventSourceUnixProcessID,

https://github.com/moses-palmer/pynput/blob/feature-injected/lib/pynput/_util/darwin.py#L284 should be

        is_injected = (CGEventGetIntegerValueField(
            event,
            kCGEventSourceUnixProcessID)) != 0
