An input control for fixed point numbers.
The spin box provides a control for entering a fixed point number. It consists of a line edit, and buttons which allow to increase or decrease the value. If you rather need input of an integer number number, use WSpinBox instead.
WDoubleSpinBox is an inline widget.
| Wt::WDoubleSpinBox::WDoubleSpinBox | ( | WContainerWidget * | parent = 0 | ) |
