HiDPI/Retina displays and qtenv

[Federico Tramarin]

Hi all,

I try to search for this argument but didn't find anything about this...

I have a Retina Mac, and qtenv appears "small", i.e. unscaled w.r.t. to the hidpi modality and to the settings of the desktop.

I am aware that Qt 5 supports this feature for a long time.

However, I didn't find a way to specify that the qtenv process should use a scaling to draw the graphics.

I tried to use an environment variable, but nothing changed.

Did someone already play into this?

Could you please help me?

Thank you very much

Federico

Hi Federico,

There isn't any specific support for HiDPI displays in Qtenv itself, but as you said, Qt does support it quite well.

Which environment variable have you tried? I just tested (on Fedora 26 and Qt 5.7.1) setting the QT_SCALE_FACTOR to values like 2, 3, or 1.5, and all of them worked perfectly, as expected.

Does this variable work for you?

Attila
