[Solved] QObject::installEventFilter(): Cannot filter events for objects in a different thread.
-
Hi,
I am just using a single thread but I get this warning:
QObject::installEventFilter(): Cannot filter events for objects in a different thread.
and my application just crashes after that.
What should I look for to fix this?

Hi,
Did you make sure that you construct QCoreApplication/QGuiApplication/QApplication first, before doing anything else?
Is this code for an application or a shared library?

- Yes
- Application

I will paste the backtrace if it helps:

It was a memory corruption somewhere.
Backtrace was misleading.Marking it as solved.
