The title is a little vague so I'll try and describe the problem as best I can in the post. I'm trying to bind a GUI library to Angelcode, and I've come across a problem when binding one of it's functions. The "Widget" class has a member called "setCaption" which accepts an Ogre::UTFString, and one of the UTFString constructors accepts an std::string (which is what "string" is binded to) Here's my code for registering the function

	// class GUIWidget
	result = engine->RegisterObjectType("GUIWidget", sizeof(MyGUI::Widget), asOBJ_REF ); assert_net(result>=0);
	result = engine->RegisterObjectMethod("GUIWidget", "void setPosition(float , float)", asMETHODPR(MyGUI::Widget,setRealPosition,(float,float), void ), asCALL_THISCALL); assert_net(result>=0);
	result = engine->RegisterObjectMethod("GUIWidget", "void setSize(float , float)", asMETHODPR(MyGUI::Widget,setRealSize,(float,float), void ), asCALL_THISCALL); assert_net(result>=0);
	result = engine->RegisterObjectMethod("GUIWidget", "void setCaption(const string ∈)", asMETHOD(MyGUI::Widget,setCaption), asCALL_THISCALL); assert_net(result>=0);
	result = engine->RegisterObjectMethod("GUIWidget", "const string &getName()", asMETHOD(MyGUI::Widget,getName), asCALL_THISCALL); assert_net(result>=0);
	result = engine->RegisterObjectMethod("GUIWidget", "string getCaption()", asMETHOD(MyGUI::Widget,getCaption), asCALL_THISCALL); assert_net(result>=0);
	result = engine->RegisterObjectBehaviour("GUIWidget", asBEHAVE_ADDREF, "void f()",asMETHOD(dummy,addRef), asCALL_THISCALL); assert_net(result>=0);
	result = engine->RegisterObjectBehaviour("GUIWidget", asBEHAVE_RELEASE, "void f()",asMETHOD(dummy,release), asCALL_THISCALL); assert_net(result>=0);

attempting to pass a string to the function causes a crash, but in C++ when passing an std::string, it runs without any problems? (Since I created a wrapper function in the GUIManager class to set a widgets caption from angelscript) and now my question is: Is it possible to pass a string to this function without binding the UTFString class?

In C++ when you do the following:

string myCaption;widget->setCaption(myCaption);

it is secretly changing it to:

string myCaption;widget->setCaption(UTFString(myCaption));

AngelScript can also do the same, but then you need to register the UTFString too, and also the implicit cast behaviour.

An easier way is to simply write a wrapper function for the setCaption method, e.g:

void GUIWidget_setCaption(const string &str, MyGUI::Widget *widget){  widget->setCaption(str);}

Registered with:

result = engine->RegisterObjectMethod("GUIWidget", "void setCaption(const string ∈)", asFUNCTION(GUIWidget_setCaption), asCALL_CDECL_OBJLAST); assert_net(result>=0);

wow thanks very much! It's working perfectly now :D
