Set line width from python

hello,
I am looking into how to modify the line width of displayed objects.
from the documentation, I could not find the function to modify this parameter (SALOME Geometry User's Guide: Line Width) of a displayed group.
right now I have:

count=0
listDisplayGroups=[]
for i in edges:
    listDisplayGroups.append(geompy.addToStudyInFather( geometry, i, 'groupOfedges '+str(count)))
    count=count+1
for i in listDisplayGroups:
    geom_gui.createAndDisplayFitAllGO(i)
    vectorRandColor=[random.randint(0,255),random.randint(0,255),random.randint(0,255)]
    geom_gui.setColor(i,vectorRandColor[0],vectorRandColor[1],vectorRandColor[2])

from looking at the output of dir(geom_gui) there is no attribute that appeals my attention to something that could modify this attribute of the display and in the documentation is not shown (or at least I can not find anything more than the previously mentioned link)
any clarification in how I can modify this attribute would be appreciated.
best regards.
