问题 In flex, I am trying to do date deduction and addition, but couldn't find a way to do it. e.g.: public var dateNow:Date=new Date(); How can I get the Date 3 months earlier than dateNow? Thanks!!! 回答1: You can use the Date constructor for this. The first argument to Date's constructor takes either a year or a timestamp.

I have an ArrayCollection (say a) where each item is an object For example a[i] = data:Object Where the object data has some subproperties - data.name , data.title , data.content etc. I have a DataGrid in which I want to display this data.

问题 Isn't there some way to re-write the following code, such that I don't need a gigantic switch statement with every conceivable type? Also, if I can replace the switch statement with some way to dynamically create new controls, then I can make the code smaller, more direct, and don't have to anticipate the possibility of custom control types. Before: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"> <mx:Script> <![CDATA[

问题 After some search and reading the Graphics class document, I can't find a way to specify the line style of a line. I mean whether the line is a solid one or a dotted one. Could anybody help me? Thanks! 回答1: Well there is no Dashed or Dotted line in flex.

You can do it

问题 I am trying to write something in my Flex 3 application with actionscript that will take an image and when a user clicks a button, it will strip out all the white(ish) pixels and convert them to transparent, I say white(ish) because I have tried exactly white, but I get a lot of artifacts around the edges. I have gotten somewhat close using the following code: targetBitmapData.threshold(sourceBitmapData, sourceBitmapData.rect, new Point(0,0), ">=", 0xFFf7f0f2, 0x00FFFFFF, 0xFFFFFFFF, true);
