Flex Alert.styleName不适合我 [英] Flex Alert.styleName not working for me

问题描述

我有这个代码，但是风格没有应用。我看过网络上的文章这应该工作。任何想法？

  var alert：Alert = Alert.show（您尚未储存变更。\\\
\\\
Would你想现在保存吗？，
保存答案？，
 Alert.NO | Alert.YES | Alert.CANCEL，
 this，
 handleUnsavedChanges，
 null，
 Alert.YES）; 
 
 alert.styleName =alertStyle; 
  
 
 
 
尝试使用样式表中的Alert类设置样式似乎有效，但会发出警告。我想找到已批准的方式。
 
 
 
 BTW，这是Flex 3。
 
 
 
 - 我也尝试过像
  alert.setStyle（backgroundColor，0x00FF00）; 
  
但这似乎不起作用。 
解决方案
我认为我需要调用一些东西来告诉Alert框重绘本身，您可以创建一个自定义类为了使用特定的css：
  public class CustomAlert extends Alert {} 
  
 ...然后在CSS 
  CustomAlert 
 {
 background-color：＃00FF00; 
} 
  
或更复杂的例子：
  import mx.styles.StyleManager; 
 private function init（）：void {
 alertCSS = StyleManager.getStyleDeclaration（Alert）; 
} 
 
私有函数showAlert（color：Object）：void {
 alertCSS.setStyle（backgroundColor，0x00FF00）; 
 alert = Alert.show（The quick brown fox ...）; 
} 
  
 
I have this code, but the style is not being applied.  I've seen articles on the web where this should work.  Any ideas?
var alert:Alert = Alert.show("You have not saved you changes.\n\nWould you like to save now?",
                             "Save Answers?",
                             Alert.NO | Alert.YES | Alert.CANCEL, 
                             this, 
                             handleUnsavedChanges,
                             null, 
                             Alert.YES);

alert.styleName = "alertStyle";
Attempting to set the style using the Alert class in my stylesheet seems to work, but throws a warning.  I'd like to find the "approved" way.


BTW, this is Flex 3.

PS - I've also tried stuff like
alert.setStyle("backgroundColor", "0x00FF00");
but this does not seem to work either.  I feel like I need to call something to tell the Alert box to redraw itself, but I don't know how.
解决方案
You could create a custom class in order to use specific css:
public class CustomAlert extends Alert {}
... Then in the CSS
CustomAlert 
{
    background-color: #00FF00;
}
Or a little more complicated example:
        import mx.styles.StyleManager;
        private function init():void {
            alertCSS = StyleManager.getStyleDeclaration("Alert");
        }

        private function showAlert(color:Object):void {
            alertCSS.setStyle("backgroundColor", "0x00FF00");
            alert = Alert.show("The quick brown fox...");
        }
