如何指定CSS的高度和宽度的弹性警告框？ [英] how to specify height and width of flex alert box in css?

问题描述

在我的Flex 4应用程序中，我希望所有的警告框都是特定的宽度和高度，我如何在CSS中指定它？我想避免每次我想显示一个警报时指定宽度和高度，这就是为什么我想在CSS中设置它，但看起来没有办法..
类似于这是行不通的：

  mx | Alert 
 {
 height：100; 
 width：300; 
 
  

解决方案

+像这样的代码

将样式属性定义为

  Alert {
 
 height：300; 
重量：300;注意：身高和身高      / strong>不是警报的默认样式
 
 
 
在代码中使用它们
  var alert：Alert = Alert.show（Hello World）; 
 alert.explicitHeight = Number（alert.getStyle（height））; 
 alert.explicitWidth = Number（alert.getStyle（weight））; 
  
 Flex3的工作示例是
 
 
 <？xml version =1.0encoding =utf-8？> 
  creationComplete ={show（）}> 
< mx：Style> 
 Alert {
 
 height：300; 
重量：300; 
} 
< / mx：样式> 
< mx：Script> 
 <！[CDATA [
 import mx.controls.Alert; 
 private function show（）：void 
 {
 var alert：Alert = Alert.show（Hello World）; 
 alert.explicitHeight = Number（alert.getStyle（height））; 
 alert.explicitWidth = Number（alert.getStyle（weight））; 
} 
]]> 
< / mx：Script> 
< / mx：Application> 
  
解释 
 
 
自提示默认情况下 支持高度和权重 风格 >将用户定义的值保存为变量。
 
 
 
在屏幕上显示 Alert / Popup 使用 Alert 类的静态 show 方法，该方法返回创建/活动的实例/对象 Alert / Popup，使用这个参考，它的属性可以像上面的例子 explicitHeight 和 explicitWidth 那样在运行时进行操作。
 
 
 
希望帮助
 
In my Flex 4 app I would like all my alert boxes to be a specific width and height, how do I specify that in the CSS? I want to avoid having to specify the width and height every time I want to show an alert, that's why I'd like to set it in the CSS, but does not look like there's a way to..
Something like this does not work: 
mx|Alert
{
  height: 100;
  width: 300;
}

解决方案
You can do it Using Style + Code like this

Define Style Properties as 
Alert {

        height:300;
        weight:300;
    }
Note: height and weight are not default style of Alert

Using them in Code as
var alert:Alert = Alert.show("Hello World");
alert.explicitHeight = Number(alert.getStyle("height"));
alert.explicitWidth = Number(alert.getStyle("weight"));
Working example of Flex3 is
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
    creationComplete="{show()}">
    <mx:Style>
        Alert {

            height:300;
            weight:300;
        }
    </mx:Style>
    <mx:Script>
        <![CDATA[
            import mx.controls.Alert;
            private function show():void
            {
                var alert:Alert = Alert.show("Hello World");
                alert.explicitHeight = Number(alert.getStyle("height"));
                alert.explicitWidth = Number(alert.getStyle("weight"));
            }
        ]]>
    </mx:Script>
</mx:Application>
Explanation

Since Alert Control by default not support height and weight style, so example used them just for holding user defined values as variable.

In routine to display Alert/Popup on screen Static method show of class Alert is used, which returns the instance/object of created/active Alert/Popup, using this refrence its properties can be manipulated at runtime as done in above example i.e. explicitHeight and explicitWidth.
