This is a little experiment to play with a different method of selecting items in a Flex List control. It allows you to re-create some of the multiple selection options you usually get by holding down the control or shift keys while you select items. But now you don’t need to hold down the control or shift keys. Just play with it to see what I mean, it’s hard to explain.
There was a question on flexcoders that was about something like this. I’m not sure if this little experiment solved the right problem for the original poster, but trying to figure out how to get some of the functionality of using the control and shift keys without using the actual keys was kind of interesting (what can I say… item renderers and list controls turn me on). So this is what I came up with. Another thing to note is that the checkbox acts as a visual indicator only, it is not actually a clickable control.
