Question

I need to use checkbox as radiobutton.
In my case I’d like to define a checkbox group but I don’t know why.
If I select one checkbox, I’d like that other checkbox are deselecting

Could you help me ?

Thanks

If there is a static amount of radio buttons you need, you could use Spark States.

<s:states>
    <s:State name="check1"/>
    <s:Stage name="check2"/>
</s:States>

<s:CheckBox selected="false" selected.check1="true" click="currentState='check1'"/>
<s:CheckBox selected="false" selected.check2="true" click="currentState='check2'"/>

When you click the first one, it triggers the “check1” state in which the first check box is selected and the other is unselected. Clicking the second one does the opposite. Obviously, this is not as flexible as some would hope. But if it’s for an interface element (such as an options menu), it’s perfect.

States are incredibly useful if you understand how and when to use them. This past weekend, I created an all-Flex slideshow using them and it is a great example of how powerful that simple little array can be.

EDIT: I just threw together a simple app to test this, and it doesn’t look like it will work using click. I’m sure you could tinker with another event to get it to work, though. Sorry this didn’t work.
