flex4

问题 this problem is really killing me so any help will be really great :) I have a flex 4 application that loads a flex module. In this module I 'register' a bunch of fonts. I have a Spark textArea in this module that wants to use one of these fonts via its text flow which is created using: textArea.textFlow = TextConverter.importToFlow(htmlText, TextConverter.TEXT_FIELD_HTML_FORMAT); I 'register' the font using: [Embed(source='/assets/fonts/book/HogarthScrD-Regular.ttf', embedAsCFF="true"

I would like to make that image cutomizable so that when the component is inserted, either the default image is used or a new image can be provided. Please

问题 I have prepared a very simple test case to demo my problem. Please just place the 2 files below into a Flash Builder 4.6 project and they will run instantly.

问题 I'm doing some programmatic validation of some field values in a form, is there any way in Actionscript to highlight the field in red the way the validators do? 回答1: you just need to set errorString property on programmatic validation error <s:TextInput errorString="error string value" /> <mx:TextInput errorString="error string value" /> 回答2: Using: var textField:TextField = new TextField(); addChild(textField); To highlight the background in AS3: textField.background = true; textField
