[Kde-bindings] Qtruby Screenshot example program does not work on Windows

-------------------------

I tracked this down to a problem with the QWidget::winId() const method.  It returns a HWND__* which is not in the Smoke ClassMap.

Here is a snippet from smokedata.cpp from smoke/qtgui:
static Smoke::Class classes[] = {
    { 0L, false, 0, 0, 0, 0, 0 },	// 0 (no class)
    { "HBITMAP__", true, 0, 0, 0, 0, 0 },	//1
    { "HDC__", true, 0, 0, 0, 0, 0 },	//2
    { "HFONT__", true, 0, 0, 0, 0, 0 },	//3
    { "HICON__", true, 0, 0, 0, 0, 0 },	//4
    { "HINSTANCE__", true, 0, 0, 0, 0, 0 },	//5
    { "HPALETTE__", true, 0, 0, 0, 0, 0 },	//6
    { "HRGN__", true, 0, 0, 0, 0, 0 },	//7
    { "HWND__", true, 0, 0, 0, 0, 0 },	//8

All of these H*__ classes are marked external, but they are not in any of the smoke modules.

This causes qtruby to crash in Qt.cpp resolve_classname here:

    if ((o->smoke->classes[o->classId].external)) {
        Smoke::ModuleIndex mi = o->smoke->findClass(o->smoke->className(o->classId));
        o->smoke = mi.smoke;
        o->classId = mi.index;
        return qtruby_modules.value(mi.smoke).resolve_classname(o);
    }

The call to findClass returns NullModuleIndex which then causes a seg fault at the return line.

I'm guessing similar problems would arise for methods using any of these H*__ classes.

Is this a bug in Smoke, or how should Qtruby be handling these classes?

Thanks,
Ryan
