Augmenting objects on per instance basis PART 2

Title: Bericht

Dear All,

 

this post is a continuation on my original post, as can be found in Lua Digest, Vol 110, Issue 2, item 6.

 

the original problem of:

 

mywidget1 = widget.create(100,100,10,10)

mywidget2 = widget.create(110,110,20,20)

 

function mywidget1:leftclick

print("left click widget 1")

end

 

function mywidget2:leftclick

print("left click widget 2")

end

 

Is now solved by the solution provided by mr ge Weijers (see Lua Digest, Vol 110, Issue 2, item 20).

 

However, this requires me to call functions on the widget in the form:

 

widget.func(mywidget1,funcparam)

 

(refer to the file LUA widget test.lua as posted by mr Weijers)

 

But I want:

 

mywidget1:func(funcparam)

 

I'm unable to modify the sample provided by mr Weijers so this syntactic sugar works....(the samples provided on the Lua books, work, but then I have the original problem back again.

 

Any hints appreciated

 

Regards,

 

Max
