FlexGui custom buttons was created by Dave3891

Hi,
I am working on a FlexGui for a waterjet and I want to have some custom buttons that call hal and emc functions.
I see I can import a python module and do the "from functools import partial" to get the parent, but does the parent also pass access to hal and emc?

I am trying to make a custom stop button that will turn off some hal output pins with hal.set_p() and then call emc.abort() in python so it will turn off the jet and sand when pressed. I also need to make one that will pause by setting the hal pins off and setting the motion.adaptivefeed to 0.

Any help would be appreciated

For anyone else with this question, this seems to work
parent.command passes the connection to emc

Code:

from functools import partial
import hal

def startup(parent):
    parent.JetOnBtn.clicked.connect(jet_on)
    parent.JetOffBtn.clicked.connect(partial(jet_off, parent))

def jet_on():
    hal.set_p("lcec.0.4.out-01", "True")
    print('Jet On')
    
def jet_off(parent):
    hal.set_p("lcec.0.4.out-01", "False")
    parent.command.abort()
    print('Jet Off')

If you use partial and pass the parent then you have access to everything.

There is a #flex-dev channel on the Libera.Chat which I monitor usually.
