Oh I do exactly the same thing - hack away till it works :)
I just started about 6 months a head of you!
I was thinking I might not have been clear about the postgui() method.
here is the relevent code:
def postgui(self):
inifile=self.linuxcnc.emc.ini(sys.argv[2])
postgui_halfile = inifile.find("HAL", "POSTGUI_HALFILE")
return postgui_halfile,sys.argv[2]
This returns the postgui file name (if there is one) and the INI path
This is in the touchy class definition code.
usually you would call it like this:
filename,inipath = self.postgui()
when called like this python automatically calls the method with the instance
name first.
that is why in the definition code [ def postgui(self) ] it uses 'self'
self represents the instance name
but when called out side of the touchy class you must call it like this:
filename,inipath = touchy.postgui(hwg)
because you are outside the class, python doesn't know what instance or class
you
are referring to. so you must specify the touchy class and the hwg instance.
clear as mud hey!
Don't ask me how many tries it took for me to get that right!
