Nice. Would be even more useful if the tooltip belonged to a custom widget, and set its position relative to that widget.

Qt Quick should be used for all UI development on mobile devices. The approach described in this article (based on QWidget) is deprecated.

This code snippet shows how to add tool tips to a QWidget. The QToolTip class provides tool tips (balloon help) for any widget. The tip is a short piece of text reminding the user of the widget's function. It is drawn immediately below the given position in a distinctive black-on-yellow color combination. The class QToolTip has static method showText(), which shows tool tips at given position.
