No, I'm referring to what is called the standard pixmap:

http://doc.qt.io/qt-5/qstyle.html#StandardPixmap-enum

The definitions work with the standardIcon member function.  There is 
enough variety there (about 70) to cover a lot of functions.  Perhaps 
they aren't scalable vector graphics though.  Maybe they match the 
desktop theme, maybe not.  I've not explored all the various 
possibilities of definitions and icon sizes--only a few uses in other 
applications for information and help icons (which comes out like a 
round, red-white life preserver).

The icons needed to supplement common file routines (e.g., 
debugger-related functions, and whatever else comes up) don't appear in 
the icon set at the link you provided.  At least, not what I saw.
