So I’m currently working on my first mxml project at work (I’ve done other stuff but not at work so they were much less involved).<\/p>\n
I realized a little in to the project that using the TextArea control can be a bit of a pain the ass at times. Namely, I couldn’t find a way to embed fonts that were loaded into the flash and set in a stylesheet that I set the TextArea to use.
The problem here was that the textArea component only looks for a single font attributed to it in the styleName attribute that cna be set. If it doesn’t see that there’s a font there it sets embedFonts = false.<\/p>\n
So liking to have as much control over things as possible, and realizing that not being able to embed my html goodness was not acceptable, I extended the TextArea class and after some finagling managed to discover the best means for fixing this. It appeared that the UITextField within the TextArea was dispatching a textFieldStyleChange event after it did it’s validation. This alowed me to add a listener to the textField and set the embedFonts attribute to whatever I chose. Here is my class: <\/p>\n
\r\n import flash.events.Event;\r\n import mx.controls.TextArea;\r\n import mx.core.mx_internal;\r\n use namespace mx_internal;\r\n\r\n public class TextArea extends mx.controls.TextArea\r\n {\r\n public var embedFonts:Boolean = false;\r\n \r\n public function TextArea()\r\n {\r\n super();\r\n \r\n }\r\n private function handleTextFieldStyleChange(event:Event):void\r\n {\r\n textField.embedFonts = this.embedFonts; \r\n }\r\n mx_internal override function createTextField(childIndex:int):void\r\n {\r\n \r\n super.createTextField(childIndex);\r\n textField.addEventListener(\"textFieldStyleChange\", handleTextFieldStyleChange)\r\n }\r\n }\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"So I’m currently working on my first mxml project at work (I’ve done other stuff but not at work so they were much less involved).
