RE: GTK & ROOT

Hi Federico,  

I have no idea, I never use Python...

Wim, could you follow, please?  

Cheers, Bertrand.

Hi, thanks a lot for the hint.  

Unfortunately, using python I'm already stuck with creating the TAppliaction. My simple test is :  

import numpy

import pygtk

pygtk.require('2.0')

import gtk,sys  

# create an instance of TApplication
 

sys.argv=numpy.array(sys.argv) #in order tohave sys.argv interpreted

gMyRootApp = ROOT.TApplication("My ROOT Application", len(sys.argv),sys.argv)    

# tell application to return from run

gMyRootApp.SetReturnFromRun(true);  

and I get:  

Traceback (most recent call last):

  File "test.py", line 12, in <module>

    gMyRootApp = ROOT.TApplication("My ROOT Application", len(sys.argv),sys.argv)

  File "/root/lib/root/ROOT.py", line 391, in __getattr1

    self.__finalSetup()

  File "/root/lib/root/ROOT.py", line 454, in __finalSetup

    if appc.CreatePyROOTApplication():

Exception: std::bad_alloc (C++ exception)  

What are the argc and argv calls supposed to pass? (in my case of course argv contains ['python','filetest.py']  

Many thanks,

Federico
