Error when using VCP Actions was created by cgibbons
Hi there,
I am running LinuxCNC 2.7 and Glade 3.8.6 on Raspbian Stretch.
I can get the HAL Python and VCP Actions to show up in my Glade Palette on the left when I runin the same terminal I am running LinuxCNC from.
However, when trying to create a new interface while following this tutorial , everything works fine until I add the VCP ToggleAction ESTOP. Then I get the following errors in my terminal and sometimes Glade just crashes and closes.
I have read many forum posts and google links trying to find the answer to this but have been unable to solve it. Any help would be greatly appreciated.

The offending line in the handler code is here:
github.com/LinuxCNC/linuxcnc/blob/master.../hal_actions.py#L205
The VCP on/off button has the same structure, does that work?
Is the output above from a running linuxCNC instance, or from an attempt to run the screen standalone?

I have looked at this line in the code before but it doesn't help me fix the error.
The actions do not show up in my inspector on the right hand side of my screen in glade. Once I click on some other widget, I cannot find the action anywhere.
I have tried those too but i get these error messages in my terminal:The VCP on/off button has the same structure, does that work?

There won't be a linuxcnc object for the GladeVCP to link to unless LinuxCNC is running.
You can probably ignore the e-stop warnings. It might be interesting to see if they go away if LinuxCNC is actually running at the time.

You can try right clicking the action and add as a top level.
In general you should save your work often - GLADE can be glitchy.

I think that is an understatement. To the extent that once I have a panel set up I don't dare try editing it with Glade, I use a text editor
I got the feeling that the newer version (which doesn't work with LunuxCNC) was more responsive and less glitchy.

Right clicking and adding it as a top level, makes it show up in my inspector on the right, whether I have linuxCNC running or not. Thank you cmorley.
I am going to have LinuxCNC running in the background from now on anyway, though LinuxCNC doesn't seem to be appearing as an object either way.
I am running glade/linuxcnc from different shell windows (as I wouldn't be able to run them both from the same window at the same time), that doesn't matter does it? As far as I know I can't run them both from the same shell window.

If you use "linuxcnc &" then linuxcnc will launch and return control to the shell.

Oh great, Thank you! I have been using the terminal an insane amount in the last two years, can't believe I never came across this.
