E-STOP button behavior

Hi,
how would I change the behavior of E-STOP button background color?
Current implementation changes color after clicking.
I would like to change button background color based of E-STOP status (it is, that if machine is in estop condition, the button would not change the color even after cliking it)

I have opened probe_basic.ui in Qt Designer and since REF ALL has similar behavior to what I want for E-STOP, where REF ALL changes to HOMED based on all_axes_homed.
I found that it has Dynamic property "rules":[{"channels": [{"url": "status:all_axes_homed", "trigger": true}], "property": "Text", "expression": "'HOMED' if ch[0] else 'REF ALL'", "name": "reference_all"}]

This kind of works with button name:
[{"channels": [{"url": "status:estop", "trigger": true}], "property": "Text", "expression": "'ESTOPPED' if ch[0] else 'ESTOP'", "name": "estop"}]

So I guess I need something similar for button background color.
Maybe it would be easier to make new style in probe_basic.qss and change styles using similar rule
I think it would be good to have visual reference to estop status.
Can you please point me in right direction?
Thanks

 

that's a good idea! widget rules, i will actually make that change to the main ui branch!

Thanks! It works fine. I replaced the two changed files in my probe_basic directory.
I dont know how this works, but will this be merged into main branch and later into package available in apt?

If you are using the 2.9.1 image of linuxcnc on the downloads page, the QTPYVCP repo is all set up so 

sudo apt update
sudo apt upgrade

Should get any updates that Lcvette and the QTPYVCP team publish to their repository. I think they have a buildbot setup at their end.

I used APT installation:
kcjengr.github.io/probe_basic/quick_start_apt.html
Which uses this apt repository:
repository.qtpyvcp.com/apt develop main
So I am not sure I will get the update.
The changes, that Lcvette made, are in branch estop_button_color:
github.com/kcjengr/probe_basic/tree/estop_button_color

I'll let Chris advise you here as I don't know how probe basic works but normally you would type
git clone <url>
git checkout <custom_branch_name>

Thanks for your patience.
I know I can checkout particular branch using git clone, but I was curious if/when this gets to an official release of the probe basic, which would be available for install in this guide:
kcjengr.github.io/probe_basic/quick_start_apt.html

If you did apt install then you will get all updates we pusface it's. Branch on your next sudo apt update , sudo apt upgrade. 

The estop update is in the latest release.
