How to realize emergency stop, pause and recovery

I'm trying to make a GUI myself, but I don't know how to emergency stop / pause / resume. I want to write and implement a button and function myself. How should I do it?
Thank you

I would use gstat to signal the button based on linuxcnc state:

linuxcnc.org/docs/2.8/html/gui/GStat.html

and the python interface to change linuxcnc state.
linuxcnc.org/docs/2.8/html/config/python-interface.html

This is how qtvcp and gladevcp do it .

I may need such a function. If an IO signal is sent, I need to make a judgment and then make an emergency stop to stop each axis and Linux CNC
Thank you very much for your reply. I hope you can help me

cmorley post=217454 userid=482我会使用 gstat 来根据 linuxcnc 状态发送按钮信号：

和 python 接口来改变 linuxcnc 状态。
linuxcnc.org/docs/2.8/html/config/python-interface.html

qtvcp 和gladevcp 就是这样做的。



I read the python interface function of Linux CNC, but I don't seem to find the emergency stop function. Thank you for your reply
