Issues compiling modeltest with Qt 5.1
I've just finished (kinda) working on my QAbstractItemModel subclass, trying to verify it with "modeltest":http://qt-project.org/wiki/Model_Test. After editing some more obvious errors I'm left with one compilation error in method ModelResetCommand::emitPostSignal(), which looks like this:
The error is 'reset' is not a member of 'DynamicTreeModel', where QAbstractItemModel is a QAbstractItemModel subclass that does indeed have no reset() method. Ideas anyone?
Sorry, but what is your point? If m_model does not have a function "reset()", you cannot call it. It just will not work.
If m_model is secretly of a different kind that has access to a reset()-function, cast it to that kind before calling the function.
The point is this is a module from Qt repository that's supposed to work out of the box.
What kind of object is m_model?
DynamicTreeModel, which is a subclass of QAbstractItemModel. Source code: https://qt.gitorious.org/qt/qt/source/57756e72adf2081137b97f0e689dd16c770d10b1:tests/auto/modeltest
I do not see the connection between your problem and the Model_Test. In your very own slot (right?) you are requesting a function of an object created by you, and that function is implemented at no point. Did you maybe mean "resetInternalData":http://qt-project.org/doc/qt-5.1/qtcore/qabstractitemmodel.html#resetInternalData ? If not, you will have to implement a function called "reset" or nothing will happen.
If I understand correctly, the Model_Test will abort your application if some kind of error pops up during runtime. If the application doesn't compile in the first place, the error should be found somewhere else.
No. What I'm talking about is an error compiling modeltest.cpp from the repository.
Ok, it seems I misunderstood you, sorry.
"reset()":http://qt-project.org/doc/qt-4.8/qabstractitemmodel.html#reset has been a member of QAbstractItemModel before Qt 5 and was then moved to the "Compatibility Members":http://qt-project.org/doc/qt-5.1/qtcore/qabstractitemmodel-compat.html .
It seems there is no single replacement for reset(), and therefore you may have found a bug, depending on where you dug up your line of code.
Fair enough, I guess modeltest hasn't been adapted to Qt 5 yet. Thanks.
You could have a look at the "bug report system":http://bugreports.qt-project.org to see whether there's already something about this. If not, create a new bug report with a minimal example that reproduces the problem.
