Text控件的leading样式学习。
示例:


代码:

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/05/31/setting-the-leading-on-a-text-control-in-flex/ -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout
="vertical"
        verticalAlign
="top"
        backgroundColor
="white">

    
<mx:Script>
        
<![CDATA[
            private function init():void {
                slider.value = txt.getStyle("leading");
            }
        
]]>
    
</mx:Script>

    
<mx:String id="lorem" source="lorem.txt" />

    
<mx:ApplicationControlBar dock="true">
        
<mx:Form styleName="plain">
            
<mx:FormItem label="leading:" direction="horizontal">
                
<mx:HSlider id="slider"
                        minimum
="0"
                        maximum
="10"
                        snapInterval
="1"
                        tickInterval
="1"
                        liveDragging
="true" />
                
<mx:Label text="{slider.value}" />
            
</mx:FormItem>
            
<mx:FormItem label="height:">
                
<mx:Label text="{txt.height}" />
            
</mx:FormItem>
        
</mx:Form>
    
</mx:ApplicationControlBar>

    
<mx:Text id="txt"
            text
="{lorem}"
            leading
="{slider.value}"
            textAlign
="justify"
            width
="400"
            preinitialize
="init();" />

</mx:Application>

也可以通过CSS来设置:

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/05/31/setting-the-leading-on-a-text-control-in-flex/ -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout
="vertical"
        verticalAlign
="top"
        backgroundColor
="white">

    
<mx:Style>
        Text {
            leading: 12;
        }
    
</mx:Style>

    
<mx:Script>
        
<![CDATA[
            private function init():void {
                lbl.text = txt.getStyle("leading");
            }
        
]]>
    
</mx:Script>

    
<mx:String id="lorem" source="lorem.txt" />

    
<mx:ApplicationControlBar dock="true">
        
<mx:Form styleName="plain">
            
<mx:FormItem label="leading:">
                
<mx:Label id="lbl" creationComplete="init();" />
            
</mx:FormItem>
            
<mx:FormItem label="height:">
                
<mx:Label text="{txt.height}" />
            
</mx:FormItem>
        
</mx:Form>
    
</mx:ApplicationControlBar>

    
<mx:Text id="txt"
            text
="{lorem}"
            textAlign
="justify"
            width
="400" />

</mx:Application>

也可以通过AS的方法来设置:
<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/05/31/setting-the-leading-on-a-text-control-in-flex/ -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout
="vertical"
        verticalAlign
="top"
        backgroundColor
="white">

    
<mx:Script>
        
<![CDATA[
            import mx.events.SliderEvent;

            private function init():void {
                slider.value = txt.getStyle("leading");
            }

            private function slider_change(evt:SliderEvent):void {
                txt.setStyle("leading", evt.value);
            }
        
]]>
    
</mx:Script>

    
<mx:String id="lorem" source="lorem.txt" />

    
<mx:ApplicationControlBar dock="true">
        
<mx:Form styleName="plain">
            
<mx:FormItem label="leading:" direction="horizontal">
                
<mx:HSlider id="slider"
                        minimum
="0"
                        maximum
="10"
                        snapInterval
="1"
                        tickInterval
="1"
                        liveDragging
="true"
                        change
="slider_change(event);" />
                
<mx:Label text="{slider.value}" />
            
</mx:FormItem>
            
<mx:FormItem label="height:">
                
<mx:Label text="{txt.height}" />
            
</mx:FormItem>
        
</mx:Form>
    
</mx:ApplicationControlBar>

    
<mx:Text id="txt"
            text
="{lorem}"
            textAlign
="justify"
            width
="400"
            preinitialize
="init();" />

</mx:Application>
