[Swig-user] Problem with standard data types

[Jared M. <eag...@ee...>]

I'm fairly new to swig, so I'm sorry if this question is answered in the
documentation.  It's quite a large learning curve.

 

I'm using SWIG to wrap C++ in to C#.  I'm having a problem with numerous
functions that take regular data types as arguments.

 

This function, for example:

 

C++

      bool  injectKeyDown(uint key_code);

 

When it's wrapped, this is the resulting code:

 

  [DllImport("CeguiBindings", EntryPoint="CSharp_GuiSystem_InjectKeyDown")]

  public static extern bool GuiSystem_InjectKeyDown(HandleRef jarg1,
HandleRef jarg2);

 

The first argument, as I understand it, is the necessary HandleRef for
keeping the GC from cleaning stuff up.  The second argument SHOULD be that
UINT, but for some reason it's using another HandleRef.

 

I don't have this problem when using custom data types.  Here's an example
of a function that is working:

 

C++

      bool  injectMouseButtonUp(MouseButton button);

 

"MouseButton" is an enum (right, left, etc.)

 

The wrapped code for this one is like this:

 

  [DllImport("CeguiBindings",
EntryPoint="CSharp_GuiSystem_InjectMouseButtonUp")]

  public static extern bool GuiSystem_InjectMouseButtonUp(HandleRef jarg1,
int jarg2);

 

As you can see, the first argument is a HandleRef. no problem.  The SECOND
argument is the value of the enum, and is being passed in as an INT.

 

Why is SWIG not doing this for the first example?  Do I need to write some
sort of custom .i code for these functions to cause swig to take that uint
value properly?
