Questions tagged [spinbox]

A spin box— also called a spinner control—is a collective term for the combination of a text box with an up-down control. Users can click arrow buttons (the up-down control) or press the UP ARROW or DOWN ARROW key to change the value in the text box. The value ascends or descends incrementally.

Spin boxes are useful when users don’t need to see the whole range of values in order to make a selection.

Example of spin box with Java

public class CyclingSpinnerListModel extends SpinnerListModel {
    Object firstValue, lastValue;
    SpinnerModel linkedModel = null;

    public CyclingSpinnerListModel(Object[] values) {
        super(values);
        firstValue = values[0];
        lastValue = values[values.length - 1];
    }

    public void setLinkedModel(SpinnerModel linkedModel) {
        this.linkedModel = linkedModel;
    }

    public Object getNextValue() {
        Object value = super.getNextValue();
        if (value == null) {
            value = firstValue;
            if (linkedModel != null) {
                linkedModel.setValue(linkedModel.getNextValue());
            }
        }
        return value;
    }

    public Object getPreviousValue() {
        Object value = super.getPreviousValue();
        if (value == null) {
            value = lastValue;
            if (linkedModel != null) {
                linkedModel.setValue(linkedModel.getPreviousValue());
            }
        }
        return value;
    }
}

Example of spin box in python:

from tkinter import *

master = Tk()

w = Spinbox(master, from_=0, to=10)
w.pack()

mainloop()
