To clarify J-P's answer:

QStringListModel* myModel = new ... declares a new local variable myModel,
that then hides the member variable with the same name. That means that no
value is assigned to the member variable myModel, which is referenced by
your check() function.

Personally, I use a prefix m_ for the names of membervariables. That makes
them easy to spot (and s_ for statics, and g_ for globals). Those can be
assigned, but never declared inside a member function.
