It came up in discussions at the QtWS that even if we have Tumbler,
people still want and expect to have the good old SpinBox control.
SpinBox has it pros, such as that it might work better inside a
vertical Flickable, and that in multi-field forms it might visually
align better with other controls like TextFields.
An early mockup of SpinBox was removed in 1c0edf0. A quote from the
commit message:
SpinBox is a desktop centric control. It won't be provided in
Qt Quick Controls 2.0, but maybe later when desktop support is
re-considered. Qt Quick Controls 2.0 will focus on embedded and
mobile. SpinBox is still available in 1.x.
While it is true that SpinBox might not be optimal for touch or
mobile, the real reason for the removal was that validating decimal
number input is very complicated. Even though locales have well-
defined thousand separators and decimal points, users have very
different expectations on how strict or relaxed the input
validation should be.
This change re-introduces a touch-optimized integer-based SpinBox.
What makes it more touch friendly than the earlier version is that
it has now auto-repeating buttons. Limiting it to integers avoids
the decimal number input validation problem. We can introduce a
separate DoubleSpinBox later if necessary - just like in QtWidgets.
