validator blues ... UltimateListCtrl and validating a TextCtrl element in a cell

wxPython Users
1

Ok,

so I do have difficulties understanding the validator, i.e. transfering
data.
Short: I want to be able to fill a ListCtrl with data and allow the user
to enter some values which i later transfer back to my dict
I am now on UltimateListCtrl that allows for a textCtrl to be placed in
a cell.
I want to transfer data to it and from it but it does not work - i
basically did what I've been doing w/ textVtrl validators all along
which worked.
MAYBE IT'S JUST THE LACK OF SLEEP BUT I AM STUCK ...

Attached a sample ulc.py based on Andrea's ReportStyle demo

What am I doing wrong?

ThanX

I am no expert of validators, as I normally prefer another approach to check the validity of the user’s inputs. Anyway, what is it that is not working?

1. I am open to whatever works (how would you do it?- I am far from

fluent in wx.Python yet but the validator concept gives me the
creeps) to let me a: insert values in a multiline list with some
cells that accept user input b: lets me read these values back

:-)

2: In my attached sample you see that I have a dict (w/ one

key/value pair) data{}

I created a Ulc and put a textCtrl into the 1st cell- Now I want to

1st transfer the data of that dict to the TextCtrl and later
transfer it back.

But the TextCrtl would not be filled w/ the data, i.e. the

validator’s self.list.TransferDataToWindow() doesn’t do anything …

(The data is read from a SQlite DB into a dictionary. it is a list

of products and I need the user to tell me how many items are
required )

I think I would just load the data and save it with a button instead of using validators in this case, see attached.

In case you have lots of items in "data" then you might want to come up with a way of just doing the SaveData bit for the items which have changed.
