Qt support for Retina screen display
I would like to know what is the best way for Qt interface widgets to support Retina screen displays?
Well all Widgets should be placed in layouts.
I didn't get your answer.
well the main issue with Retina is all get too small.
If you design your app so it uses layout for both
main window and all sub widgets, it can all
scale very easy.
