Undefined reference to vtable when inheriting QFrame

I'm using Qt 5.4 x86 on Windows 8.1 Pro x64. Following this example I'm trying to implement an ElidedLabel class. Not sure what I'm doing wrong, but the code in the example itself is producing

error: undefined reference to `vtable for ElidedLabel'

What's wrong and how to fix it? I've checked the Qt 5.4 documentation of QFrame and there is not a pure virtual function that needs to be defined.

moc (Meta Object Compiler) didn't preprocess your code, so you get this not very clear error.

Solution: try the Build > Run qmake command from the menu. This command will run moc and it will generate correct code for your class.
