WkNumericEditorView

The WkNumericEditorView part provides a means for editing integer values. Since it is specifically designed for integers, WkNumericEditorView ensures that only integers are entered. To further restrict valid values, the range of valid numbers can be bounded by minimum and a maximum values. A user can increment or decrement the values using up/down arrow keys or by selecting the up/down buttons. A user can change the value in an editable spin button by typing in the entry field.
