Set QStyle in QTCreator to view style while designing

[askasmani]

I am currently developing QT Application on Macos, I want to use Fusion/Windows style.

I am currently setting the style in Main.cpp, I have to run the application everytime to see the style in action.

Can I set the style for the application in QTCreator, so I can see the style while designing instead of having to run the application and see it in action.

Example design in QTCreator: While Designing see how tabs are labeled.

When running the application, I want to see the tabs the same way in QTCreator as well:

Thanks,

Ahmed.
