Re: [wxlua-users] wrap acces violation

[Klaas Holwerda]

Hi John,

I managed to change the wxLuaCan sample to create the same error.
If you unpack the source code in the attached file, to apps/wxluacan/src,
and run the sample, you get it.

The two pointers are:

wxlLuaCanCmd* wxlLuaCanCmd1;
wxlLuaCanCmd* wxlLuaCanCmd2;

And in wxluacan.i they are wrapped like here:

%class %delete %noclassinfo wxlLuaCanCmd, wxCommandProcessor

    %define_pointer wxlLuaCanCmd1

    wxlLuaCanCmd( wxlCan* canvas, int maxCommands = -1 )
    void MoveObject( int index, double x, double y )
%endclass

%class %delete %noclassinfo wxlLuaCanCmdDer, wxlLuaCanCmd

    %define_pointer wxlLuaCanCmd2

    wxlLuaCanCmdDer( wxlCan* canvas, int maxCommands = -1 )
%endclass

Stack at crash time is:

I think this makes it much easier to find for you,
