[Pytables-users] Problem walking through structure of an hdf5 file and pygtk treeview

[Philou <Kal...@wa...>]

Hi list,

I want to display all the node of an hdf5 in a treeview but reflecting 
exactly the hdf5 structure of the file.
For example i try to display this structure in a treeview:

 / (Group)
-> columns (Group)
    -> name (Array)
    -> pressure (Array)
    -> test (Group)
-> detector (Group)
    -> readout (Table)

Here you probably recognize the structure of the tutorial hdf5 file  
except that i add an empty group test in columns group. ;)
My problem is i didn't succeed to display the real structure of the hdf5 
file in a treeview.

When i use a for loop listing nodes, it's not exactly the structure of 
the hdf5 file:
for node in h5file:
    components_list.append({'name':node._v_name, 
'type':node._v_attrs.CLASS})

the result is:
/
columns
detector
name
pressure
readin
test
readout

The problem is the group detector is displayed after the group columns 
and before the childs of the group columns.
So when i display it in a treeview, detector is part of columns group.

I use for the moment this loop:
for group in h5file.walkGroups("/"):
            if  group._v_name == "/":
                iter0 = self.__model.append(None, [group._v_name,"group"])
            else:
                iter1 = self.__model.append(iter0, [group._v_name,"group"])
            for array in h5file.listNodes(group, classname = 'Array'):
                if iter1 == None:
                    iter2 = self.__model.append(iter0, 
[array.hdf5name,"array"])
                else:
                    iter2 = self.__model.append(iter1, 
[array.hdf5name,"array"])
            for Table in h5file.listNodes(group, "Table"):#"Table"):
                if iter1 == None:
                    iter3 = self.__model.append(iter0, 
[Table.hdf5name,"Table"])
                else:
                    iter3 = self.__model.append(iter1, 
[Table.hdf5name,"Table"])

and add a different but not better result:

 / (Group)
-> columns (Group)
    -> name (Array)
    -> pressure (Array)
-> detector (Group)
    -> readout (Table)
-> test (Group)

How can i display the real structure of an hdf5 in a treeview?
Thanks in advance,
I'm sad to go into week end without solving this problem :/.
Have a good week end,
