Set italic font

Hi all,

i have a Gnome::Canvas::Text *t and i'd like to set the font style in italic. For doing this i have a function:

void OGClass::setItalic(bool res)
{
	PangoStyle s;
	if(res) s = PANGO_STYLE_ITALIC;
	else s = PANGO_STYLE_NORMAL;
	t->property_style_set() = true;
	t->property_style() = s;
}

The compiler gives no errors, but at runtime i receive this message

 GLib-GObject-WARNING **: unable to set property `style' of type `PangoStyle' from value of type `glibmm__CustomBoxed_10PangoStyle'

and nothing happen. Any idea?
Thx,
Mark
