Signal/Event Handler for window's scale percentage change indication

Maikkannan

Hi,
I'm developing application in Qt creator 4.9.0.
Qt library : 5.12.2
OS : Windows 10

I'm trying to fix the scaling issues in my application to make the application adopt with different scaling percentage. So that I need to know Is there any signal/event handlers to indicate the updates/changes on windows scaling percentage ? whenever user changes Setting >> Display >> scale and Layout >> 100%,125%,250%...% .

Thanks,
Maikkannan.

Hi
Should come from QScreen but im not sure
Please see if
logicalDotsPerInchChanged(qreal dpi)
will fire when you change the scaling.
