I'm trying to decipher how to have a postgui hal file with my custom
GUI. The following snippet I assume does the magic of loading the
postgui file. Some I understand and some I don't.
if __name__ == "__main__":
if len(sys.argv) > 2 and sys.argv[1] == '-ini':
print "ini", sys.argv[2]
hwg = touchy(sys.argv[2])
else:
hwg = touchy()
res = os.spawnvp(os.P_WAIT, "halcmd", ["halcmd", "-f",
"touchy.hal"])
if res: raise SystemExit, res
# load a postgui file if one is present in the INI file
postgui_halfile,inifile = touchy.postgui(hwg)
print "TOUCHY postgui filename:",postgui_halfile
if postgui_halfile:
res = os.spawnvp(os.P_WAIT, "halcmd", ["halcmd",
"-i",inifile,"-f", postgui_halfile])
if res: raise SystemExit, res
gtk.main()
The line hwg = touchy(sys.argv[2]) what is that doing?
Also what is postgui_halfile,inifile = touchy.postgui(hwg) doing?
Somehow it seems that postgui_halfile is being set to > 0 if one is
found in the ini file but I don't understand how that line does that?
Thanks
John
