Comments on: Flex Bindings in AS3 Projects

Yes, essentially what the SignalDataBinding API buys you is the ability to implement data binding in AS3 projects. I wouldn’t necessarily suggest using it in place of Data Binding in Flex, however if ever Signals were being used exclusively and data binding was needed the SignalDataBinding API would provide a convenient solution.

This was more or less an exercise resulting from my evaluation of AS3 Signals to see what they have to offer. To be honest, I wouldn’t use it over Binding in Flex. However, I wanted to publish the API as I do feel it would provide value for those who might disregard AS3 Signals because of data binding limitations. This would also suit non-Flex projects well. One argument which I feel would warrant the use of AS3 Signals over Flex data binding would be if something a bit more light weight was warranted (for instance, where event bubbling isn’t necessary, such as in the PM examples).

1–BindingUtils is 4k.

2–BindingUtils does work dandy for AS3 projects. you can also import BindingUtils into a fla/document project, but it won’t work, because the Flash IDE won’t write code for the binding metadata.

i have been trying to make the code below work. no success. it is an actionscript file not flex.
ChangeWatcher.canWatch(buttons, “left”); always give ‘false’.
————————————————
import mx.binding.utils.ChangeWatcher;
import mx.events.FlexEvent;
import mx.events.PropertyChangeEvent;

var buttons:Object = {left:0, right:0};

var watchable:Boolean = ChangeWatcher.canWatch(buttons, “left”);
ChangeWatcher.watch(buttons, “left”, fnWatch);
function fnWatch(e:PropertyChangeEvent){
trace(“buttons changed”);
};
trace(“watchable ” + watchable.toString());

test1_btn.addEventListener(MouseEvent.CLICK, leftClicked);
function leftClicked(e:MouseEvent){
buttons.left = (buttons.left + 1)%2;
};
test2_btn.addEventListener(MouseEvent.CLICK, rightClicked);
function rightClicked(e:MouseEvent){
buttons.right = (buttons.right + 1)%2;
};
