Re: [Wxlua-users] multi-level C++ namespaces

[Darwin Slattery]

Hello,






I have the following declaration:
namespace nsa
{
class MyClass
{
public:
   enum MyEnum
   {
       ENUMVAL1 = 10
   };
};
}

The corresponding entry for the enumeration in the .i file is:
%enum nsa::MyClass::MyEnum
   %rename nsa_MyClass_ENUMVAL1 MyClass::ENUMVAL1
%endenum



Also when accessing this value within a lua script I use:
wxluanstest.nsa_nsa_MyClass_ENUMVAL1



Thanks again for all your time and help,
Darwin Slattery

Thanks that works great. The naming convention for the namespaces is perfect. I have noticed something regarding enumerations declared inside a class in a namespace that I just wanted to check with you. I could not put the 'nsa::' before 'MyClass::ENUMVAL1' because it results in a compile error saying that nsa::nsa isn't declared. It works fine but I just wanted to check if I'm using this properly. I have attached the source again in case you want to try it out.

Thanks for your reply. I think I'm just missing something small here. From
your suggestions it seems that what I'm trying to do is completely possible

to declare a class within another class declaration - I just want to write
bindings for classes that have been declared in mulit-level namespaces like
nsa::nsb::nsc.

in the .i file. Just to clarify one point in your last mail, I'm not looking

It was a very small fix, but in a few different places. In order to
make it work you have to use the fully qualified namespace for both
the %class and the constructor.

The output will be nsa_nsb_MyClass which is reasonable enough, right?
It's too much trouble to try to make nested lua "namespaces" like
wx.nsa.nsb.MyClass.

%class %delete %noclassinfo %encapsulate nsa::nsb::MyClass
   nsa::nsb::MyClass()
   %rename nsa_nsb_MyClassFromInt nsa::nsb::MyClass(int x)
    %constructor nsa_nsb_MyClassFromInt(int x)

You use the %rename tag or %constructor tag for alternate
constructors, but you must replace the :: with _.

Thank you for your offer of looking at the code. I definitely don't want to

The attached archive has the .i and MyClass header file and I've included a
main driver file and makefile.

cause any work for you or the team and any suggestions would be appreciated.

Thanks for the sample, it really helps and saves me a lot of time when
I people give me a nice little sample to work with.

The next snapshot will contain the fixed binding generator.
