Would it for such static sizes (why 60px in the first place?) not be more \
"correct" to use sh. like 60*100*2/(widget->physicalDpiX()+widget->physicalDpiY()) \
where "100" wold be the "standard" dpi? (could also be eg. 72 or 96)
Right now (in latter RRs) you assign various configurable icon sizes to \
"remotely" related views. That might be correct and intended, but it's also a \
behavioral change and this time, desktop icons /can/ be assigned to 256px through the \
GUI - even on a 72dpi screen - and that's unlikely the intended size here.

The only issue that remains is the initial size of the dialog to make it show 4 rows \
of icons. In the current implementation it just adds another 100px to the dialog \
height (cf. line 490), which is easy, if all the sizes are known and fixed, but with \

probably need to add a sizeHint (tried in the private class, didn't help there)? \
