Increase QT code performance

[s002wjh]

Is there ways to increase the performance of QT main thread without going to multithreading

For example telling Linux to run QT in multiple CPU concurrently or run QT as multiple processes

All my code are widgets class, to do multithreading I need move a lot code around into Qobject. So I'm looking for easier performance methods

Hi
You cant run anything QWidget concurrent so nope.
Not really.
What part of the code is slow?

@mrjj

So basically the only way to make run faster is to move my worker functions that calculate the pixel position. Put in Qobject and create thread for it?

hi
It really depends on the code and if you then can run multiple
calculations concurrently.
Just moving a big fat loop to a QObject+qthread wont make it
run faster but perhaps make UI more responsive.
