getting problem wth multi selection list

[furqanraza]

Hi,

I'm getting some problem in multi selection list. I'm working on files to get data. I have two functions save_list() and load_list(). When I'm loading data from file using load_list() into multi selection list then it is showing that there is no data. On the other hand if I'm printing it using print command, it is printing List.

My code is following:

mylist = [u"Mobile",u"Python"]
save_list(u"c:\\mydata.txt",mylist)


newlist = load_list(u"c:\\mydata.txt")
choices = appuifw.multi_selection_list(newlist,'checkbox',1)

How can I resole this problem.

Waiting for your kind reply.

Hi furqanraza
i think if you are loading something from the file that means you are reading something from the file.
So first you have to open the file and then read it then probably use that in multi_selectionlist.

Hope you got the point

yes I'm doing the same thing. It is the functionality of load_list() function to open the file. Here is code:

def load_list(filename):
   myfile = file(filename,"r")
   lst = []
   for line in myfile:
      lst.append(line.strip())
   myfile.close()
   return lst

def save_list(filename,lst):
   myfile = file(filename,"w")
   for item in lst:
      print >> myfile, item
   myfile.close()

consder an example,

suppose there is a data [u"Mobile",u"Python"] in mydata.txt

now,

list = load_list(u"c:\\mydata.txt")

if I'll write

print list

then it is printing the list ['Mobile','Python']

If I assign this list to multi_selection_list then it is showing that "No Data"


Now, tell me how can I solve it?

Hi furqanraza
i am not sure but i think you cant pass functions or objects in the multiselsction list but i may be wrong investigating with the code just wait will be back.

[furqanraza]

but load_list function is retuning a LIST and even it is printing successfully. While I'm passing LIST into multi_selection_list, it is saying "no data".

I got one point.

when I'm saving data into file as unicode like:

mylist = [u"Mobile",u"Python"]
save_list(u"c:\\mydata.txt",mylist)

But it is printing like this when I load the data

['Mobile','Python']

May be some unicode issue.

I'm trying to resolve it. If you get any idea about it, then please let me know.

Hi gaba88,
I have resolved this problem. Bit change in load_list(). I'm adding this code may be helpful to other.
Using unicode instead of simple string.

def load_list(filename):
   myfile = file(filename,"r")
   lst = []
   for line in myfile:
      lst.append(unicode(line.strip()))
   myfile.close()
   return lst
