How to draw shadow in a rectagle

[Mr Gisa]

I was wondering how to draw a shadow in a rectangle like this one (top and bottom only):

Our designer sent this file for me and I have to draw this manually using QRect. The second image describes the position of the shadow.

Hi

But you can make drop shadow effects with

Maybe your designer seems to have used a gradient pattern. like this:

background-color: qlineargradient(spread:reflect, x1:0, y1:0.574, x2:0, y2:0.306182, stop:0 rgba(0, 0, 155, 255), stop:1 rgba(0, 0, 127, 255));
