问题 I have a sprite that I do some custom drawing in, but I would like the container to know where to position the sprite properly. To do this, the container needs to know how big the sprite is. UIComponents go through a measure stage, but sprites don't . How do I calculate the size that a sprite will be? Edit: I'm doing the drawing in Event.ENTER_FRAME, and it's animated, so I can't tell ahead of time how big it's going to be. The UIComponent has a measure function and I'd like to create

问题 I'm using CF to retrieve values from a database that are then being stored in a datagrid in Flex. I then want to selectively take the value from one cell of the datagrid and store it as a string variable. I've searched around, but I haven't been able to come about a solution. The users will not be interacting at all with the datagrid as it will be hidden to them. Any help? 回答1: Why are you bothering to use a DataGrid if it is hidden to the user? Store your data in an ArrayCollection of

问题 Project setup is Flex 3-BlazeDS-Spring Flex Integration-Grails Dependency injection in my Service classes was working just fine with Grails 1.2.1, when service methods were called from my flex client. When I upgraded my project to 1.3.3 yesterday using the regular 'grails upgrade' command, everything went well but once I started the app, dependency injection no longer seems to work in my Grails Service classes.

问题 In flexbuilder 3 for some mxml files I can purposely put in syntax errors and the compiler will seem to compile the specific page(but actually not compile it) or report any errors for that page. Is there any way that you know of to get the compiler to report the errors to me so I can get it to compile the page.

问题 The initial height of a text area is much larger than the content, I cannot find a way of making it always the same height as the text content: <mx:TextArea id="textarea" borderStyle="solid" width="100%" wordWrap="true" selectable="false" backgroundAlpha="0" focusAlpha="0" text="this is a little test" /> Gives a bordered box that is much taller than needed.
