Is this the best way to do it though? I.e. having one item per cell?
s there another way at all?<br>
I'm still a bit lost in the model/view design and can't find the
answer online.<br>
<br>
I'm simply trying to have each row represent a "task" with a
title/description (string), a status (boolean) and a priority
(integer). For the integer I need a spin box and for the boolean I
need a checkbox. The examples I found online all seem to be doing
something slightly different and often use different ways which
makes matters more confusing.<br>
<br>
Here is what I have at the moment:<br>
<a title="http://pastebin.com/H3GD0xVB" class="moz-txt-link-freetext" href="http://pastebin.com/H3GD0xVB" target="_parent">http://pastebin.com/H3GD0xVB</a><br>
<br>
The "status" and "priority" values don't display currnelty as I
haven't figured out how to properly assign a delegate to just those
cells. At the top I tried to define a n item delegete for a spin box
but I'm not sure how to properly assign it.<br>
<br>
Do I have to make the delegate draw different widgets (spin box /
checkbox) depending on data type, or can/should I use a different
delegate for each cell?<br>
<br>
I'm sure the answer is right in front of me, could you please help
one more time please?!<br>
<br>
Cheers,<br>

you mean to use a QStandardItem per cell then yes.<br>
Also for storing values that you want to display, use the
Qt.DisplayRole as role.<br>

[PySide] simple QTableView example</span><br>
<br>
</div>
one more silly question if I may:<br>
So if I have a task like this:<br>
newTask = {'title':'new task', 'priority':1,
'status':False}<br>
<br>
and need to store the data in one row in the model I should use
three different items, one for each value, right?!<br>
<br>
e.g.:<br>
<br>
newTask = {'title':'new task', 'priority':1,
'status':False}<br>
row = self.model.rowCount()<br>
for column, attr in enumerate(['title', 'priority',
'status']):<br>
newItem = QtGui.QStandardItem(newTask[attr])<br>
self.model.setItem(row, column, newItem)<br>
<br>
then juggle delegates or widgets to use a spin box for the integer
and a checkbox for the boolean...<br>
<br>
Thanks for the help!<br>
<br>

<div><font face="Consolas" style="font-size: 10pt;"># Store data

<div><font face="Cambria"><font face="Consolas" style="font-size: 10pt;">priority = model.data(item_index,
PRIORITY_ROLE)</font></font></div>
</div>
<div>
<div> </div>
<div>In some cases like click event handlers, you have the
model and the item index, there it’s easier to use the
model methods instead of finding the item and then getting
the data. <span><span style='font-family: "Segoe UI Symbol","Apple Color Emoji";' data-externalstyle="false">😉</span></span></div>

After looking at some more examples I think my approach of
storing multiple values in one item is fundamentally flawed.<br>
Instead I should be using one item per cell and assign the
respective data, right?!<br>
<br>
I shall re-write the example accordingly, sorry for the noise.<br>

<br>
after a bit of a break from PySide I am trying to wrap my
head around the model/view stuff again and am trying to
understand how a very simple example would work where a
QStandarItem has properties "title", "priority" and
"finished" which are displayed via a QStandardTableView.<br>
<br>
I am struggling with understanding how to properly display
the above three properties in the table's columns. I tried
setting the data() method on the model like this:<br>
<br>
<i> def data(self, index, role=QtCore.Qt.DisplayRole):</i><i><br>
</i><i> '''Return data based on index and role'''</i><i><br>
</i><i> item = self.itemFromIndex(index)</i><i><br>
</i><i> if index.column() == 0:</i><i><br>
</i><i> return item.title</i><i><br>
</i><i> elif index.column() == 1:</i><i><br>
</i><i> return item.finished</i><i><br>
</i><i> elif index.column() == 2:</i><i><br>
</i><i> return item.priority</i><br>
<br>
but for some reason it errors saying item does not have
attribute "finished" even though my item object s declared
like this:<br>
<br>
<i>class TaskItem(QtGui.QStandardItem):</i><i><br>
</i><i> '''Item to hold a task for the todo list'''</i><i><br>
</i><i> </i><i><br>
</i><i> def __init__(self, title, finished=False,
priority=1):</i><i><br>
</i><i> super(TaskItem, self).__init__(title)</i><i><br>
</i><i> self.title = title</i><i><br>
</i><i> self.finished = finished</i><i><br>
</i><i> self.priority = priority</i><br>
<br>
<br>
When printing the item's attributes via dir() I see that,
when the model is populated, the last item it attempts to
call is not my custom item object, but something else with
less attributes and methods. Clearly there is something I
haven't quite understood about this process.<br>
<br>
Also, if I use the models data() method as pointed out
above, I get checkboxes in the cells which I don't want at
this stage.<br>
<br>
Can somebody please help me understand where I go wrong?<br>
Attached is the whole test code.<br>
<br>
Cheers,<br>
frank<br>
<br>
P.S.: I am aware that the controller code shouldn't
necessarily live in the QWidget's methods, this is just
for testing which I will clean up once I get how it all
connects again<br>
