Starting from an app based on QtWidget class, with a lot of widgets one overlying each other, is it possible to set contrast and brightness controls (e.g. two slides) as in photo editing programs? Can I act globally on my own project?
Currently I used Qt 4.8.6.

Hi,

Do you mean create a widget containing two QSliders ?
