问题 Within a specific canvas, I would like a user to be able to press a combination of keys which will trigger an event.(a bit like a cheat in an old megadrive game). Not sure where to start though. Anyone know if it is possible and if so could you give me a clue with how to start? Thanks in advance! 回答1: You can add an eventListener to the top level application for the KeyboardEvent.KEY_DOWN event and check for key combinations there. From this article: <mx:Application xmlns:mx="http://www.adobe

问题 I am trying to create Adobe Air application in which I require the components below: Allow me to elaborate this mockup: There are 2 panels on each side, and the items inside these panels can be drag and drop on each other, just like moving items around in 2 folders. Several tutorials have shown that a list with dragEnabled = "true" dropEnabled = "true" dragMoveEnabled = "true" will do the job. However, here comes the crucial part. I want my item in the list to have such a structure that I

问题 I need to fetch a String from a clob Oracle column using Hibernate without lazy loading and without using a Criteria query. It currently returns a proxy class (ex. $Proxy30) but I need a String (or something I can convert to a String). The proxy is for oracle.sql.CLOB according to the debugger. When I use a Criteria query (with just the regular Column annotation mapping for this field), this works just fine. But we have one area where we "build" a custom SQL query which uses a simple org

问题 (Flex 3) I have a TextArea component which needs to hold the user's clipboard content. The TextArea does the job relatively well for most cases but when pasting a large amount of data, I can't seem to get the content in the component at all due to the script execution timeout. I've done a fair deal on investigation to try and hopefully find how I could make this work. I found that the TextArea is using a IUITextField (which is in my case an instance of TextField at runtime) do handle the job

问题 I am trying to achieve a Photo gallery where images are showed in thumbnails whenever i select a certain folder of images. For example, if i were to click on the folder A, it will load all the images into a arraylist which will be set as the dataProvider for in my List to create the tilelayout. But i realized that, if i have 500 images, and whenever i scroll down on my scrollview, it kind of lags. Is there any way where it will load all my images first, before displaying? Or any way to make

问题 How to convert date and time to CDT time Zone in flex4 Regards, Sushma 回答1: The Date object in Flash is always set to the computer's time settings. If the computer is already in the CDT timezone, then just getting any property from the object will be good. However, if you want to do a timezone 'conversion' into a timezone that the computer is not set to, you can get the UTC time and offset it like this: var date:Date = new Date(); var timezone:int = -5; date.hours = date.hoursUTC + timezone;
