Thanks Milind and Antonio,
I'll have to study that up.

The explanation is here :

Function definition is like this actually:
functiondef ::=*function* funcbody
funcbody ::= ‘*(*’ [parlist] ‘*)*’ block*end*
So in your example this works:
box[key].click = function(self,L,C)
end
The other way is just syntactic sugar and the does not accept square brackets.

Hi,
I've been doing a bit of programming with IUP LUA under windows.
And have discovered this oddness.
===========
require( "iuplua" )
require( "iupluacontrols" )
box = {}
key = "999"
box[key]= iup.matrix {numcol=2, numcol_visible=2, numlin=0}
local box_key = box[key] -- This works
function box_key:click_cb(L,C)
end
-- The function def below doesn't like the [key], doesn't compile
function box[key]:click_cb(L,C)
end
========
I'm at a loss to understand why the latter function doesn't compile.
Any advice greatfully received.
