Modify the variable QT_SCALE_FACTOR when the program is running

[Francky033]

Hi!

In an application, I use the qputenv command in my main.cpp file to fix the size of my QML dialog boxes

qputenv("QT_SCALE_FACTOR",scale);

There are two problems:

• The command crashes the program under macos if scale != 1.0

• Since it is only possible to change the system variable QT_SCALE_FACTOR when the program starts, I can no longer use this way to change the size of the boxes once the program has started.

Is there another way to act on the variable QT_SCALE_FACTOR? or to act on the same parameter when the program is running?

With my thanks,

[JonB]
