Re: [Wxlua-users] forward declarations

Hi,

I start realizing that forwrad is not always needed.
In the next a2dCentralCanvasCommandProcessor needs to be there first, or 
genwxbind.lua gives errors.
Interesting enough, a2dCommandLanguageWrapper is not knwo, but that is oke??

%class %delete %noclassinfo a2dCentralCanvasCommandProcessor
    a2dCentralCanvasCommandProcessor()
%endclass

%class %delete %noclassinfo a2dLuaWrapper, a2dCommandLanguageWrapper
    %define %pointer a2dLuaWP
    a2dLuaWrapper( a2dCentralCanvasCommandProcessor* commandProcessor )

If i remove the %class .... a2dCentralCanvasCommandProcessor, i get the 
following error.

c:\data\art2d\a2dren9\modules\luawraps\src>genwxbind.bat
Generating wxWidgets Binding
loaded rules: luawraps.rules
Error: Expected Parameter '=', ')', or ',' got Tag='*'. 
(Name=a2dCentralCanvasCo
mmandProcessor; Undefined DataType) File: 
C:/data/art2d/wxArt2D/modules/luawraps
/src/luawraps.i:(line 14)


So i think i don't understand when something has to be know upfront or 
when not?
And when something has to be knwo, how to make it know without 
generating code for a complete class.
I just need pointer to it.

regards,

Klaas
