Detailed Description

widget for entering numbers with spinbox functionality. It uses less horizontal space than a QSpinBox and allows entering numbers in scientific notation.

The widget supports the functionality of a regular QSpinBox, i.e. the value can also be adjusted using arrow keys and mouse wheel. If the widget cannot accommodate the current number representation of the value, the representation will be changed to scientific notation once the widget looses focus. While the widget is in focus the number is shown in regular notation, except for values less than 1e-6 which are depicted in scientific representation.
