The user can also type the value in - manually. The spin box supports integer values but can be extended to - use different strings with validate(), textFromValue() and valueFromText(). - - Every time the value changes QSpinBox emits the valueChanged() - signals. The current value can be fetched with value() and set - with setValue(). - - Clicking the up/down buttons or using the keyboard accelerator's - up and down arrows will increase or decrease the current value in - steps of size singleStep(). If you want to change this behaviour you - can reimplement the virtual function stepBy(). The minimum and - maximum value and the step size can be set using one of the - constructors, and can be changed later with setMinimum(), - setMaximum() and setSingleStep(). - - Most spin boxes are directional, but QSpinBox can also operate as - a circular spin box, i.e. if the range is 0-99 and the current - value is 99, clicking "up" will give 0 if wrapping() is set to - true. Use setWrapping() if you want circular behavior. - - The displayed value can be prepended and appended with arbitrary - strings indicating, for example, currency or the unit of - measurement. See setPrefix() and setSuffix(). The text in the spin - box is retrieved with text() (which includes any prefix() and - suffix()), or with cleanText() (which has no prefix(), no suffix() - and no leading or trailing whitespace). - - It is often desirable to give the user a special (often default) - choice in addition to the range of numeric values. See - setSpecialValueText() for how to do this with QSpinBox. - - \table 100% - \row \o \inlineimage windowsxp-spinbox.png Screenshot of a Windows XP spin box - \o A spin box shown in the \l{Windows XP Style Widget Gallery}{Windows XP widget style}. - \row \o \inlineimage plastique-spinbox.png Screenshot of a Plastique spin box - \o A spin box shown in the \l{Plastique Style Widget Gallery}{Plastique widget style}. - \row \o \inlineimage macintosh-spinbox.png Screenshot of a Macintosh spin box - \o A spin box shown in the \l{Macintosh Style Widget Gallery}{Macintosh widget style}. - \endtable - - \section1 Subclassing QSpinBox - - If using prefix(), suffix(), and specialValueText() don't provide - enough control, you subclass QSpinBox and reimplement - valueFromText() and textFromValue().
