问题 I'm currently using the JPGEncoder from the AS3 core lib to encode a bitmap to JPEG var enc:JPGEncoder = new JPGEncoder(90); var jpg:ByteArray = enc.encode(bitmap); Because the bitmap is rather large (3000 x 2000) the encoding takes a long while (about 20 seconds), causing the application to seemingly freeze while encoding. To solve this, I need either: An asynchronous encoder so I can keep updating the screen (with a progress bar or something) while encoding An alternative encoder which is

问题 I'm trying to handle the mouseWheel event in an advancedDataGrid with not success. Without any additional code my adg can be scrolled with the mouse in IE but not in firefox and Chrome, why?

问题 Is there any difference between single and double quoted strings in ActionScript? 回答1: You can use either as delimiter for a string. They are however not interchangeable, i.e. you can't start a string with an apostrophe and end it with a quotation mark. The only difference is which characters you need to escape. Inside a string delimited by quotation marks you need to escape quotation marks but not apostrophes, and vice versa. To put the text He said "It's all right" and laughed. in a string
