Hi Sebastien,
The Drawable method you are look for is:
/** Return OpenGL display list for specified contextID. */
inline GLuint& getDisplayList(unsigned int contextID) const {
return _globjList[contextID]; }
However, your usage model so sounds rather outside the usage for the
OSG, users don't normally
ever need to access values such as display lists ID as this is all
managed behind the scenes for you.
I know almost nothing about your specific needs or app so can't say
whether what you are doing
is appropriate or not, but all I can say is its sounds atypical and as
such you may well hit lots of
gotchas, and using the OSG how its meant to be used might well be far
more productive.
Robert.
