Sorry if I was not clear enough :
Tell me if I undernstand well : you propose to parse the SWT toolkit,

That was my suggestion, yes! Not necessarily on the fly, but to avoid
hand-building the metamodel.
And since every public properties, methods and events will be in the
metamodel, the "runtime engine" will run easily.
Exactly!
Unfortunately, not applicable in the current project, because :
* There is 2 metamodels, an abstract one is required because to rule
future extensions or replacement of the SWT concrete one,
* the SWT meta model is not a 100 % mapping of SWT toolkit -- for
instance, colors, fonts are objects, could be share among several
components and of course color changes are reflected to their containers.
This is to be expected. Perhaps its possible to find some heuristics for
generating a metamodel that is very close to what you want. To avoid more
hand-modeling than necessary.
BTW, in XSWT we currently use reflection directly. However, we've been thinking
of pre-generating a lookup-table, as suggested above, to be used on platforms
that lack reflection, like JME.
