I could build and attach with a debug probe of Qt 5.3.0, it work, I can see
the QuickScene objects and modify properties. If I do some method invoke
with return value, I never get an answer, is there something special to do
to make it work? Should I enable the -qmljsdebugger=port: hook to get the
After building, I end up with a debug probe only, is there a way to build a
release probe for GammaRay and would it work?
Connections are now shown, invoke seem to work, but the return value is
lost, a lot of loading. If I can run in in release build it would be good
enough for some usage.
