D27958: [SystemTray] Fix item size for very narrow panel

[Konrad Materka]

kmaterka added a comment.


  I don't like how icon size and item size (container = icon + padding) are calculated and used... Firstly best icons size is calculated, but then padding are added. This combined size is used as item size (container size):
  
  - SNI icons are rounded to nearest icon size (implicitly, because  PlasmaCore.IconItem is used)
  - Plasmoids are scaled to the size of the container, I don't know exactly how it work, probably because default compact representation is just an icon.
  
  By happy coincident it is (?) working correctly for all sizes.
  
  There is also a lot of anchoring involved, all items are aligned to left (which looks bad with expander arrow, gap is bigger) etc. But all of this can be fixed in separate patch.
