4.19.9.3 Widget Identifiers

On occasion you may need to name a widget, in order to identify it for some future operation. Consider the example below.

 
<layout type="page">
	<widget type="Gauge" id="myGauge">
		<type>{Skin.current.Style.GaugeLevel}</type>
		<title>My Gauge</title>
		<min>0</min>
		<max>100</max>	
	</widget>
	<widget type="Slider" id="mySlider">
		<vertical>{true}</vertical>
		<step>25</step>
		<lock>{false}</lock>
		
		<event name="onChange" action="function() { myGauge.value = mySlider.value; }" />
	</widget>
</layout>

By using the "id" attribute, you can given a widget a name that is referenceable later. Note that the names need to be globally unique, since they are created in the global namespace.
