Field '_var' has incomplete type

[lespaul]

Hello, I got I library inwich I have another class as a QPointer
QPointer<Other_Class> _var;

I use this somewhere else, and it works fine.
Then I created another class,
Lib_Class * _libClass;
and suddenly it wont work with the message:
field '_var' has incomplete type.

I don not use forward declarations or structs here (most of web searches complain about structs or forwarddeclarations)
I dont know what else to do??

I appreciate any help and thnx in advance

Sincerly,
LesPaul

Hi and welcome to devnet,

Did you check your includes in order to use Other_Class ?

@SGaist Oh man exactly they forgot to include the
#include <QPointer>

Thnx for that help!
