Well, yes and no. Often, when you rely on the onCompleted, this points to a flaw in your code or design. (I said often, guys, flames not needed :) Sometimes these checks are necessary.)
However, in your specific case, you could actually solve this without problems: value: settings.trackWidth onValueChanged: { if (value != settings.trackWidth) { settings.trackWidth = value } } Bo.
