Gremlin

gremlin-run takes command line arguments and requires a running instance of Linuxcnc.
Without either it will abort with errors, is that what you are seeing?
It will run from the command line quite happily when these requirements are met.
I am currently trying to find a way of embedding it inside my Qt GUI, don't want to have to re-implement it if I can avoid it

When I put the GladeVCP gremlin widget into my Glade file and run it I get this error.
So my thought was to try and add gremlin with my python code and see if I get rid of the error.
What command line arguments does gremlin-run take?
Thanks
John

John are you getting those errors even if linuxcnc is running?
I get those error is the GLADe editor if I don't have linuxcnc running.
I don't get them of course when Gscreen is loaded as it load linuxcnc first.
I have been meaning to look into it but of course have not yet...

I wonder if the order I have in my file makes a difference? I'll try a few things.

I still get the error... this is my main class init, I'm assuming the the line self.cnc = linuxcnc loads linuxcnc?
John
# main class
class gui7(object):
def __init__(self, inifile):
self.builder = gtk.Builder()
self.builder.add_from_file(xmlname)
self.builder.connect_signals(self)
self.cnc = linuxcnc
self.notebook = self.builder.get_object('notebook')
self.num_pad = self.builder.get_object('num_pad')
self.np_label = self.builder.get_object('np_label')
self.halcomp = hal.component('gui7')
self.panel = gladevcp.makepins.GladePanel(self.halcomp, xmlname, self.builder, None)
self.halcomp.ready()
self.ini_file = os.environ['INI_FILE_NAME']
self.window = self.builder.get_object('base_window')
self.window.show()John

No linuxcnc is loaded from a script when you start a config. (that's what I meant by linuxcnc)
the linuxcnc in your program is the python bindings to linuxcnc's status data and functions.
Are you starting this program like a regular config?
If so it may be that Gscreen takes longer to initialize so avoids this error.
It's cause because gremlin is trying to poll linuxcnc and linuxcnc isn't ready yet.
some sort of
try:
except:
in gremlin should fix this
