These were using a hijacked custom spin box that was designed only for
letters i.e. submodes. Now there are two new custom spin boxes.
HistedSpinBox:- can be set with a list of integer values which the
step up and down will follow. Optionally limits the maximum and
minimum value to the upper and lower bounds of the values set. Note
that intermediate values are still valid.
RestrictedSpinBox:- more like a combo box because the provided values
are the only ones that can be set.
HintedSpinBox is used for the frequency tolerance and
RestrictedSpinBox is used for T/R period.
