Just the application that wants to use those special icons, so that would be just plasmashell. It goes like this: - Application creates new SNI - Plasma is notified through a dataengine - The dataengine reads all the SNI properties, including IconThemePath property - The dataengine sets the the additional path on KIconLoader (where appName is the app the SNI belongs to) - Plasma loads the icons using the QML component IconItem (which uses QIcon::fromTheme() which in turn uses KIconEngine aaand that uses KIconLoader) The additional paths are added at the end of the list and it's usually one directory only in case of the SNIs, so the rise of the number of lookups is not that dramatic because about 99% of all icons are found before the lookup even reaches the normal hicolor theme and so this adds only one lookup per registered application in the worst case only. Plus there is icon cache which also helps things. > On June 5, 2014, 10:22 p.m., Christoph Feck wrote: > > src/kiconloader.h, line 209 > > <https://git.reviewboard.kde.org/r/118561/diff/1/?file=279078#file279078line209> > > > > Are we still allowed to break binary compatibility?
