So, in short:
I have application resources like
and I call QIcon::setThemeName("breeze") and one of the actions in an
.ui file has
and this seems to work on Linux (it falls back to hicolor and finds
the myapp-action.svg icon), but not on macOS. There it will find e.g.
"document-open", but not "myapp-action".
I would have thought that since Qt allows embedding of a theme
following the icon theme specification in the resources on
Mac/Windows, that it would also implement the fallback behavior (to
hicolor) in the spec, among the resource-embedded themes.
