Hi Christian,
I'll refer only to the multi-threading part of your mail.
The THREAD flag enables some mechanism to make ROOT canvas operations
thread-safe and to build the TThread-class. Then you can do in ROOT things
like what you stated in your mail and access a canvas by several threads
etc.
Please refer to the release notes of ROOT to find the features and some of
the critical limitations we found out. Additionally we will talk at the
ROOT workshop on our experiences with the ROOT TThread-class, GUI and
Canvas and all that stuff.
A special point about the GUI class is that you have to be sure about your
Xlib. This seems to be the critical point in this respect.
Greetings,
Marc
