问题 I have figured out a way to change the style of tabs at run time with following logic: var cssStyle:CSSStyleDeclaration = StyleManager.getStyleDeclaration(".MyTabs"); cssStyle.setStyle("borderColor", "red"); But here ".MyTabs" class is applicable to all the tabs between first and last tab. As per getStyleDeclaration javadoc, it only accepts "class selector" and "type selector" not the id selector. How can I change the individual tab style at run time? 回答1: Another user pointed out a method

问题 This is in reference to My Other Question How do can you detect and dispatch an event when a drag and drop operation ends prematurely? I need to know that the user is no longer dragging an item. Even if the dragDrop and dragComplete events do no fire. Its almost as if I need to add an event listener to the dragManager, but that's not really possible... is it? 回答1: It looks like basically you need to be able to tell if the DragManager craps out. Even if there was an ERROR event in the drag

In flex I've always had to write a for each and

问题 I upload my flex client-side swf app to some website that loads different swf's on it's site. So you see your application floating in that website. My app is Flex swf app and has onCreationComplete() that starts the flow of logic. Now I want to do cleanup state and save state in a shared object when the application unloads (or probably exiting event, or closing event..) So do we have any function that I can implement and the flash platform automatically calls that function when the swf is
