\ingroup controls
\brief Provides a spin box control.
SpinBox allows the user to choose a value by clicking the up or down buttons, or by
pressing up or down on the keyboard. The user can also type the value in manually.
By default the SpinBox provides discrete values in the range [0-99] with a \l stepSize of 1 and 0 \l decimals.
\code
SpinBox {
id: spinbox
}
\endcode
Note that if you require decimal values you will need to set the \l decimals to a non 0 value.
\code
SpinBox {
id: spinbox
decimals: 2
}
\endcode
