Detailed Description

The QAbstractSpinBox class provides a spinbox and a line edit to display values.

The class is designed as a common super class for widgets like QSpinBox, QDoubleSpinBox and QDateTimeEdit

Here are the main properties of the class:

  1. text: The text that is displayed in the QAbstractSpinBox.
  2. alignment: The alignment of the text in the QAbstractSpinBox.
  3. wrapping: Whether the QAbstractSpinBox wraps from the minimum value to the maximum value and vica versa.

QAbstractSpinBox provides a virtual stepBy function that is called whenever the user triggers a step. This function takes an integer value to signify how many steps were taken. E.g. Pressing Qt::Key_Down will trigger a call to stepBy(-1).

QAbstractSpinBox also provide a virtual function stepEnabled to determine whether stepping up/down is allowed at any point. This function returns a bitset of StepEnabled.
