Flex4中SkinnableContainer圆角边框设置
Flex4中BorderContainer有一个cornerRadius属性,通过设置该属性,即可实现圆角边框效果,但设置这个属性后,4个角都会变圆,有的时候可能会有这么一种需求:我只需要设置某一两个角变圆,或者几个圆角的弧度都不一样,这个时候,cornerRadius属性的设置显然就不能满足需求。
ps:在Flex4之前可以设置borderSides属性达到类似效果,如:borderSides="top left right"
在Flex4中borderSides属性貌似已经没有了(其实flex3中很多的属性,在flex4中都没有了,已经换了其他实现方式)
那么,在flex4中要如何做才能达到上面说的效果呢?
看代码:
首先,写一个skin:
<?xml version="1.0" encoding="utf-8"?>
<s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
alpha.disabled="0.5">
<!-- host component -->
<fx:Metadata>
[HostComponent("spark.components.SkinnableContainer")]
</fx:Metadata>
<!-- states -->
<s:states>
<s:State name="disabled" />
<s:State name="normal" />
</s:states>
<!-- SkinParts
name=contentGroup, type=spark.components.Group, required=false
-->
<s:Rect left="0" top="0" right="0" width="100%" height="100%"
topLeftRadiusX="25">
<s:stroke>
<s:SolidColorStroke color="#AEADB0" alpha="0.5" scaleMode="none"/>
</s:stroke>
<s:fill>
<mx:LinearGradient>
<mx:entries>
<mx:GradientEntry color="0x333333" ratio="0.00" alpha="0.5"/>
<mx:GradientEntry color="0xfefef3" ratio="0.33" alpha="0.5"/>
<mx:GradientEntry color="0x333333" ratio="0.66" alpha="0.5"/>
</mx:entries>
</mx:LinearGradient>
</s:fill>
</s:Rect>
<s:Group id="contentGroup" left="1" right="1" top="1" bottom="1"/>
</s:Skin>
使用这个skin:
<s:SkinnableContainer width="20%" height="50" top="2" horizontalCenter="0"
skinClass="com.flyhigh.skin.BorderContainerSkin">
</s:SkinnableContainer>

圆角TextInput
在flex4中spark布局的样式都是用skin来控制,不像flex3中的mx可以使用属性来控制样式。所以spark控件已经没有了cornerRadius属性,所以要实现圆角输入框,就需要使用skin来实现。以下是实现代码,一看就明白。
DateFieldSkin:
<?xml version="1.0" encoding="utf-8"?>
<s:Skin
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark">
<s:states>
<s:State name="normal"/>
<s:State name="disabled"/>
</s:states>
<!---@private -->
<s:Rect id="border" left="0" right="0" top="0" bottom="0"
radiusX="{getStyle('cornerRadius')}" radiusY="{getStyle('cornerRadius')}">
<s:stroke>
<!---@private -->
<s:SolidColorStroke id="borderStroke" color="0x5380D0"/>
</s:stroke>
<s:fill>
<!---@private -->
<s:SolidColor id="bgFill" color="0xFFFFFF"/>
</s:fill>
</s:Rect>
</s:Skin>
Sample App:
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/halo"
minWidth="1024" minHeight="768">
<fx:Style>
@namespace s "library://ns.adobe.com/flex/spark";
@namespace mx "library://ns.adobe.com/flex/mx";
.roundedTI
{
corner-radius:10;
borderStyle: solid;
borderSkin: ClassReference("DateFieldSkin");
}
</fx:Style>
<mx:DateField textInputStyleName="roundedTI"/>
</s:Application>
