I tried with this solution:
------------------------Code Snippet----------------------------------
class Custom_List(gtk.GenericTreeModel):
def __init__(self,list=[]):
gtk.GenericTreeModel.__init__(self)
self.list=list
def on_get_flags(self):
return gtk.TREE_MODEL_LIST_ONLY|gtk.TREE_MODEL_ITERS_PERSIST
def on_get_n_columns(self):
return 2
def on_get_column_type(self, index):
return gobject.TYPE_STRING
def on_get_iter(self, path):
return self.list[path[0]]
def on_get_path(self, rowref):
return self.list.index(rowref)
def on_get_value(self, rowref, column):
return rowref[column]
def on_iter_next(self, rowref):
try:
i = self.list.index(rowref)+1
return self.list[i]
except IndexError:
return None
def on_iter_children(self, parent):
return None
def on_iter_has_child(self, rowref):
return False
def on_iter_n_children(self, rowref):
return 0
def on_iter_nth_child(self, parent, n):
return None
def on_iter_parent(self, child):
return None
------------------------Code Snippet----------------------------------
But it is much slower than the ListStore solution :-/

I can't figure how to use set_cell_data_func for this purpose
