    It's possible to make this effect (scanlines) using Gradients? Which other alternatives do I have?

      Sure, just set up one dark and one lit up line and then use QGradient::RepeatSpread to fill the outside

      EDIT: Sorry, I just noticed you want it in QML and my answer is for Qt Widgets

        Oh Thanks, I'll try it. I didn't find it in the documentation.

            hi

            @efdiloreto said in Scanlines effects on background:

            Which other alternatives do I have?

            It is possible to use @VRonin s solution
            create any visual Widget and subclass QQuickPaintedItem to expose it to QML

                That's a good resource. You'll need shaders to achieve that effect.
