Interesting.
This also does not work:
function box[key].click_cb(self, L,C)
And it is not related to IupLua. I tested with:
box[key]= {numcol=2, numcol_visible=2, numlin=0}
An the result is the same.
It seems it is not a valid Lua declaration. You should post at the Lua
list to get a better answer... :)
On the other hand, this is valid:
box[key].click_cb = function(self, L,C)
According to the Lua documentation:
The statement
function t.a.b.c.f () *body* end
translates to
t.a.b.c.f = function () *body* end
So for me it was the same as above. But then, I guess it is not. It does
not work in any Lua 5.x.
Interesting again.
Anyway, Milind already answer it. Thanks!
Best,
Scuri
