If you bind a variable to some component’s property by just adding [Bindable] metatag above it you may notice that component’s property changes when variable changes but it doesn’t work in the opposite direction. So what to do in order to achieve to way data binding?
In MXML you have to add twoWay=”true” attribute to your Binding tag.
<fx:Binding source="slider_1.value" destination="slider_2.value" twoWay="true"/>
<s:HSlider id="slider_1"/>
<s:HSlider id="slider_2"/>
<s:HSlider id="slider_1"/>
<s:HSlider id="slider_2"/>
In ActionScript you have to add @ before binded variable in component’s property.
[Bindable]
private var value:Number;
<s:HSlider value="@{value}"/>
private var value:Number;
<s:HSlider value="@{value}"/>
