解决textinput没有垂直居中的属性

 不知道为什么textinput一直没有垂直居中的属性.于是就自己写了个类,支持垂直居中 :

 

package com.sandy.global.view.component.textinput
...{
    import mx.controls.Text;
    import mx.controls.TextInput;
    
    public class VerticalMiddleTextInput extends TextInput
    ...{
        public function VerticalMiddleTextInput()
        ...{
            super()
        }
        
        override protected function createChildren():void
        ...{
            super.createChildren();
        }
        
        override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
        ...{
            super.updateDisplayList( unscaledWidth, unscaledHeight );
            
            this.textField.height = this.textField.textHeight ;
            
            this.textField.y = this.height/2 -this.textField.height/2
        }
    }
}
