I have been involved in seeing php used as a scripting language to
Delphi projects. There quite often more generic top level  objects are
exposed to script, that enabled script to do virtually anything that
the host programme can do. I realise there may be real security fears,
but defining a safe and  a stable approach to this might enable things
to happen more easily.

For example if such a thing were done, could script create new
widgets/forms etc on the fly?
In the example I just quoted that was possible, as generic functions
were prepared and made available to script, and some of the exposed
objects in the executable provided those resources any way.

It does seem useful to actually provide the base one even if more
specific functions are made available in these cases.

Then someone can dig deeper if there is something else needed, and we
can make wrapper libraries at script level, which still leaves the
'bigger' picture open.  The Qt documentation is quite well organised
and can be followed relatively easily, plus there are other support

Has any one found a site specialising in Qt scripting matters handling
some of the sorts of topics that have come up here in the last day

Others must have struck this Q_Invok able... problem perhaps and found
way through?
