Hello,
I'm trying to understand the model/view programming while making a kind of
tag-based browser. I have some absoluteFilePath in a database associated to
one ore more tags (which are strings) . I'm trying to display those files
(or directories of course) in a view. Hence, I created a subclass
finally, I did it like that:
I don't know if it's a good way to access the model in the view, but it works
class CustomQTableView(QTableView):
def __init__(self):
super(CustomQTableView, self).__init__()
def show_hide_rows(self, choice):
"""choice comes from a checkox""
I have not yet found a better way to do this than by first building a
list of rows you want to be visible, then setting the model's filter
with setFilter().

Yes, I use that in the model also.
but now, I need to iterate over the row, in the tableView. I want to
hide row when the data is an empty string.
I found that I can get the string with self.currentIndex().data().toString()
so, I suppose that I have to find a way to modify the currentIndex

Take a look at your model's rowCount() and record() methods. I think
you'll want to be iterating over the records in your model,
actually, I just want to loop over the rows.
I do not find a max_row, or an iterator over the rows of a Table.

thank you, both of you !
I will check the filtering solution.
I am now implementing the setColumnHidden. just have to customize a
QTableView class. seems simple.
by the way, do you know how to get the total number of row in a table ?
i must be blind, but I could not find it.

perhaps setColumnHidden is what you seek?

looks like that I have to do a QAbstractTableModel for each QTableView, no ?
sounds strange, I thought that the idea was to have only one model
that will serve data to several views.

Hello,
I am reading the chapter 14 of Mark Summerfield.
I work with custom model and custom delegate.
in the sample from the book, we have 1 tableView linked to one model.
It's simple to get 2 tableView linked to the same model.
my Model has got 4 columns.
I would like that TableView_1 show the
Hello,
thanks for your help again. It works like a charm now.

Hello,
i have some problems with my first attempt to use Model/View programming:
I tried to create a Model for a directory list. The folders are located on a
mobile phone and I get the content over Obex and Bluetooth, so the
communication can be really slow -> The model should be asynchronous.
