[Libqtlua-list] Question regarding accessing

[John Boocher]

Hi,

 

I have just downloaded and started analyzing QtLua and am having problems figuring out how to pass QObjects into lua functions such that they can be extracted and used in c++ code. Here is what I currently have:

 

class TestController: public QtLua::UserData

{

public:

    QTLUA_REFTYPE(TestController);

 

public slots:

 

    QString testFunc()

    {

        return "testFunc called";

    }

};

 

…

    static class Fcn : public QtLua::Function

    {

      QtLua::Value::List meta_call(QtLua::State &ls, const QtLua::Value::List &args)

      {

          meta_call_check_args( args, 2, 0, QtLua::Value::TUserData, QtLua::Value::TUserData );

          TestController::ptr controller = get_arg_ud<TestController>( args, 0 );

          QtLua::UserData::ptr d = get_arg_ud<QtLua::UserData>( args, 1 );

 

          QString retVal = controller->testFunc();

          return QtLua::Value(ls, retVal);

      }

    } fcn;

 

…

 

    _state["dialog2"] = QtLua::Value(_state, new QDialog(), true);

    _state["test"] = QTLUA_REFNEW(TestController);

 

 

In lua I make the following function call: “fcn(test, dialog2)”. The TestController instance comes through fine, and I can get the second argument as a UserData::ptr, but I can’t seem to figure out how to get the second argument as the QDialog instance.

 

Any help would be greatly appreciated!

 

Thanks!
