Ok, I think I'm now using the tester, but I'm not sure I'm using it correctly.
After I've populated my base model, assigned it as the source model to my
proxy, and then connected the models up to their respective views I call:
QAbstractItemModelTester* baseModelTester = new
QAbstractItemModelTester(mBaseModel,
QAbstractItemModelTester::FailureReportingMode::Warning,
this);
QAbstractItemModelTester* proxyModelTester = new
QAbstractItemModelTester(mInvertRowsProxy,
QAbstractItemModelTester::FailureReportingMode::Warning,
this);
And then run the rest of my application normally. On first launch after adding
those lines I saw the following statement twice in QtCreator's Application
Output pane:
qt.modeltest: FAIL! model->hasChildren(topIndex) () returned FALSE
(qabstractitemmodeltester.cpp:366)
A quick google on that pointed to the fact that I was always returning my data
size for rowCount() and 2 for columnCount() regardless of whether the parent
index was valid or not. So adding:
if(parent.isValid())
{
return 0;
}
to both rowCount() and columnCount() removed those errors and now my
application runs silently.
Am I using the model index tester correctly?
Any other ideas on how to get this working?
