        Sets the precision.

        This sets the number of digits after the decimal point shown

        The default precision is 2.

      • setValue

        public void setValue​(double value)
        Sets the value.

        value must be a value between getMinimum() and getMaximum().

      • valueChanged

        public Signal1<java.lang.Double> valueChanged()
        A signal that indicates when the value has changed.

        This signal is emitted when WFormWidget.changed() is emitted, but supplies the new value as an argument. The WFormWidget.changed() signal is emitted when the user changes the value of the spinbox by pressing the up/down arrow, or entering a different value and pressing enter or moving focus.

      • refresh

        public void refresh()
        Description copied from class: WWidget
        Refresh the widget.

        The refresh method is invoked when the locale is changed using WApplication#setLocale() or when the user hit the refresh button.

        The widget must actualize its contents in response.

        Note: This does not rerender the widget! Calling refresh() usually does not have any effect (unless you've reimplemented refresh() to attach to it an effect).

        Overrides:
        refresh in class WAbstractSpinBox
      • render

        protected void render​(java.util.EnumSet<RenderFlag> flags)
        Description copied from class: WWidget
        Renders the widget.

        This function renders the widget (or an update for the widget), after this has been scheduled using scheduleRender().

        The default implementation will render the widget by serializing changes to JavaScript and HTML. You may want to reimplement this widget if you have been postponing some of the layout / rendering implementation until the latest moment possible. In that case you should make sure you call the base implementation however.

        Overrides:
        render in class WAbstractSpinBox
