I am trying to use QAbstractTableModel and I am having more than
some difficulty.
If I return the correct number to columnCount I get no headers. If I
return a number that is too big, I get headers, but the model is
asked for headers and data for columns that don't exist!
Everywhere I return a String in the data() routine, this is
displayed with a check box - even if I cast it to QVariant.
There's a C++ class called QModelText which sanity-checks models, I
believe that an older version was converted to python and is
included in
PyQt4. Run it on your model, fix the problems and see wether that
helps.
Thanks for your reply Andreas,
I can find nothing about QModelText, and QModelTest appears to have a
few bug reports and
nowhere to download it and no instructions as to how to run it, and is
not on my hard disks.
the python version andreas is referring to is "modeltest.py". it can
be found in the pyqt source in the contrib/pymodeltest directory.
I found the version I think I need (4.7.4) at
http://python-qt4.sourcearchive.com/documentation/4.7.4-0ubuntu1/modeltest_8py-source.html
I have been unable to find out how to run it - so guessing I tried this.
# coding=utf8
from companyListModel import CompanyListModel
from modelTest import ModelTest
model = CompanyListModel()
tester = ModelTest(model, None)
tester.runAllTests()
This didn't initialise ModelTest
Traceback (most recent call last):
File "testing.py", line 8, in <module>
tester = ModelTest(model, None)
File "D:\work\C-U-B\modelTest.py", line 41, in __init__
self.connect( self.model,
QtCore.SIGNAL("columnsAboutToBeInserted(const QtCore.QModelIndex&, int,
int)"), self.runAllTests)
TypeError: type 'QtCore.QModelIndex' is not supported as a slot argument
type
I'm way out of my depth. (That usually means I'm about to learn
something.)
Help needed!
Ian
