What is the meaning of Thread affinity?

Hareen Laks

Hi,

I'm reading the Qt Documentation and get stuck at thread affinity.

Can anybody explain it to me?

Thanks for reding this.

JKSH

When a signal is emitted, Qt will call the slot function. Qt needs to choose a thread to run the function.

There are two ways to describe how Qt chooses the thread:

If the receiver QObject has an affinity for Thread B, then the slot function runs in Thread B.
If the receiver QObject lives in Thread B, then the slot function runs in Thread B.

You can change the QObject's thread affinity by calling QObject::moveToThread().
