问题 I'm trying to remove an eventlistener on (in this specific case) a HorizontalList. The list is initialized with the property itemRollOver="playPreview(event)" I'd like to remove this eventListener by switching state and stating something like: <mx:SetEventHandler target="{horList}" name="itemRollOver" handlerFunction="null" /> This doesn't seem to work. The event is still handled and playPreview(event:ListEvent) is still called. How to properly do this? (I know I can do it in Actionscript,

问题 I've implemented a custom item renderer that I'm using with a combobox on a flex project I'm working on. It displays and icon and some text for each item. The only problem is that when the text is long the width of the menu is not being adjusted properly and the text is being truncated when displayed. I've tried tweaking all of the obvious properties to alleviate this problem but have not had any success. Does anyone know how to make the combobox menu width scale appropriately to whatever

问题 For some reason, the event listener I define never seems to receive any events, although I believe it should. Here's a very short description of the MXML code I'm using: WindowedApplication VBox (root box) MenuBar TabNavigator VBox (first tab) Canvas VBox (second tab) If I add a listener for KEY_DOWN events to WindowedApplication or the root VBox, the handler receives the events just fine. But if I add the listener to the Canvas or the first tab VBox, the handler never seems to receive any.

问题 I find it much easier to write MXML classes with embedded Script than trying to make an actionscript file. I was wondering however what kind of overhead there is of using an MXML file - in terms of file size. I'm not especially concerned about performance, but if that is relevant would be interested in any findings. Obviously I'm talking about UI components that have layout. MXML is MUCH easier to visualize and modify but I'm unclear exactly what it compiles down too. I'm hoping there is a
