Qt Built Software Device Resolution Inquiry

[JVR Orane]

How can we get Qt to scale the software being built accordingly to the respected dpi per display resolution screen (ex from a 1080 to a 4k ), on Windows OS? unsure of where to find the options to be changed on the windows to enable it to scale when being run on different user screen resolutions.

Hi and welcome to devnet,

Are you asking for something like a compile time flag ?

Hi
Do you mean something like this ?
http://doc.qt.io/qt-5/highdpi.html

(if not compile time)

@mrjj not exactly. What i'm asking is if there is a way to specify a virtual resolution and virtual dpi so i can see what my application will look like on a 4k screen even though the resolution of my screen is 1080p.

@JVR-Orane
ahh. as far as i know , not really.
You could adjust QT_SCALE_FACTOR , but its not really what you are after.

@mrjj yeah its not, but thanks though
