custom slider question (very advanced)

So you told it's slider in meaning of whole control, not single image/button.
But... where shall it be "3d" as you mentioned at threads beginning?
Do you want buttons to scroll around?
I assume that you want this widget do draw partially transparently as on wysota's picture, so i think it can be i.e. scrollArea with custom paintEvent that omits background drawing.

On picture, the shape of this icon switcher is linear, i need it in circle form, like vynils or cds in jukebox.

Shall this circle be planar (according to screen's surface) or somehow 3d?

Regarding to fact, that icons in upper part of circle will be smaller (like they are more distant) than the icons in lower part of circle and the selected icon is the biggest, i think it will look like 3d.

So you want icons on sides skewed like they would be rotated?
It can be done without real 3d features with a bit of coordinates computation it can be emulated on transformed() pixmaps.

QSlider is not best base widget i think. I suggest a completely custom widget that inherits QWidget & QButtonGroup, you can add then a number of buttons & your widgets draws them in a 3d-like circle. It's reusable then...
