Yes, I've been trying that, but unity-2d-spread needs to be run as root. So I
tried running qt creator as root with 'sudo qtcreator' in my current session
but that didn't work too well. Or maybe I should set the setuid bit on the
unity-2d-spread executable so it can run as root - I'm still experimenting.
It doesn't look too hard to add a menu option 'Connect to Running QML
Application..' to 'Debug -> Start Debugging' to Qt Creator though, and I've
started doing that now too. Certainly if I need to debug unity-2d-launcher and
unity-2d-panel I'll need be able to connect to a running process anyway,
because they must be started by the gnome-session process.
Actually this does not seem correct.
First off, why do you say that you need to run spread as root ?
It should definitely not be run as root.
Second, you don't need launcher and panel to be started by the session,
if all you need is to debug them.
What you can do is to change the
/usr/share/applications/unity-2d-launcher and change the line with the
name of the executable to something that doesn't exist (to prevent the
session from starting it).
Then log out of your session and log in again. Press ctrl+alt+t to start
a new terminal and launch qtcreator from there, then start your launcher
under a debugger.
Of course if you prefer hacking qtcreator, that's great and definitely
something other people can use, but it's certainly not the quickest way
to debug this problem.
