Yeah, may be.

It's not exactly 1 to 1.  In fact and in principle it's a very
Gambas-ish interface, the same way the Gambas' component gb.qt4 is not
a 1 to 1 correspondence to the Qt library.

That's very true.  The danger is to underestimate the significance of
reasons and the number of those who are forced to.  In the current state
of affairs, how can I write a window manager in Gambas?  How can I
write a new widget tool-set entirely in Gambas?

Fair enough.


Thank you.
Happy hacking!
