16×16 in this case.

The width of the scene subview toolbar (the original icon request in this thread) is 48. But we need to subtract the width of the button border from that (QPushButton). I actually don't know if there is a fixed default value for that or if it varies from system to system. Does anyone have any info on that?

16×16 is small icon, 22×22 is medium one, 32×32 is a large one. We use small ones in the edit sub view, and most likely mediums in the scene (i would shrink it to the small, though).

So 16x16, 22x22, and 32x32

What about the advancement of display technologies? For example Apple retina display? Should the icons have high resolution versions as well?

48x48, 64x64?

Back to the original request. For the lighting part of the toolbar we need 3 icons: day, night, bright

How about a sun (day), a moon (night), and a lightbulb with some light rays radiating off of it (bright)?

Sounds reasonable.

Hopefully I'll have time this week to make them.

Little update on the icon size situation. There were actually a few problems with my original button code. These are fixed now which means the border is hardcoded to 8 pixel (4 on each side). I don't really like the hardcoding part, but I don't know any way around it. Therefore the icons need to be 40x40 now (the button with minus the border width).

Edit: Forget what I just wrote. The fix that I applied was bogus. The size is still 48x48 and we do not need to concern us with the button border.

Edit 2: Apparently the original fix was not bogus, but the one I applied afterwards was. Starting to get annoyed here. The new icon size is now 42x42. And that is the final word on that. I hope ... Maybe ...

we really should use standard sizes everywhere. that is
8×8
16×16
22×22
32×32
48×48
64×64
128×128
256×256

I really insists on getting back to the normal situation – sizes are important consitency wise, and even if they do not effect usabilty, bizzare sizes just look odd.
