Is there a way of reading the previous value of a QSpinbox?
-
As the title suggests. I'm making a function that would greatly benefit from the ability to read the previous value of a QSpinbox, and I'm wondering whether this function exists without making an int that manually reads and saves the data before the value changes. Please let me know if more info is required.

If you are talking about something like
aboutToChange(int oldVal), unfortunately not (forQSpinBoxat least).
ContextMenus have anaboutToShowsignal before they are shown, butQSpinBoxdoesn't . As soon as you get yourvalueChangedsignal, the widget itself forgets about the old value, if you haven't saved it.
