It comes from Qt::GlobalColor, and is an enum intended for usage in C++ when you construct a QColor. So the value is 7. It is accessible in QML only because everything from the Qt namespace is made available. Being able to assign this enum to a value of type QColor in QML would require a little more magic in the QML engine, which is not implemented AFAIK. I agree it feels a bit awkward to write a symbolic color as a quoted string in QML… it leaves you wondering if it is stored that way. (It isn’t, though; since any color property in Qt Quick is a QColor, it has to call the QColor constructor taking a QString. Still, a QString had to be constructed, and then thrown away. In an interpreted language, this is only a drop in the bucket.) But specifying Qt.red wouldn’t really feel much better, would it? It’s still a few extra characters to type, and it’s arbitrary to have it in the Qt namespace as opposed to a Color namespace. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
