Flex BorderContainer示例
让我们按照以下步骤通过创建测试应用程序来检查Flex应用程序中BorderContainer的用法 -
步 | 描述 |
---|---|
1 | 在cn.xnip.client包下创建一个名为HelloWorld的项目,如Flex - Create Application一章中所述。 |
2 | 修改HelloWorld.mxml ,如下所述。 保持其余文件不变。 |
3 | 编译并运行应用程序以确保业务逻辑按照要求运行。 |
以下是修改后的mxml文件src/cn.xnip/HelloWorld.mxml 。
<?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/mx
width = "100%" height = "100%" minWidth = "500" minHeight = "500">
<fx:Style source = "/com/xnip/client/Style.css" />
<fx:Script>
<![CDATA[
private function applyBorderContainerProperties():void {
borderContainer.setStyle("borderWeight",weightStepper.value);
borderContainer.setStyle("borderColor",colorPicker.selectedColor);
borderContainer.setStyle("dropShadowVisible",chkShadow.selected);
}
]]>
</fx:Script>
<s:BorderContainer width = "630" height = "480" id = "mainContainer"
styleName = "container">
<s:VGroup width = "100%" height = "100%" gap = "50"
horizontalAlign = "center" verticalAlign = "middle">
<s:Label id = "lblHeader" text = "Layout Panels Demonstration"
fontSize = "40" color = "0x777777" styleName = "heading" />
<s:Panel id = "borderContainerPanel"
title = "Using BorderContainer" width = "500"
height = "300" includeInLayout = "true" visible = "true">
<s:layout>
<s:VerticalLayout gap = "10" verticalAlign = "middle"
horizontalAlign = "center" />
</s:layout>
<s:HGroup>
<s:VGroup>
<s:HGroup verticalAlign = "middle" >
<s:Label text = "Border Weight:" width = "100" />
<s:NumericStepper id = "weightStepper" value = "1" />
</s:HGroup>
<s:HGroup verticalAlign = "middle">
<s:Label text = "Border Color:" width = "100" />
<mx:ColorPicker id = "colorPicker" color = "0x323232" />
</s:HGroup>
<s:HGroup verticalAlign = "middle">
<s:Label text = "Drop Shadow:" width = "100" />
<s:CheckBox id = "chkShadow" selected = "false" />
</s:HGroup>
<s:Button label = "Apply Properties"
click = "applyBorderContainerProperties()" />
</s:VGroup>
<s:BorderContainer id = "borderContainer" width = "200"
backgroundColor = "0xff99ff">
</s:BorderContainer>
</s:HGroup>
</s:Panel>
</s:VGroup>
</s:BorderContainer>
</s:Application>
一旦准备好完成所有更改,让我们像在Flex - Create Application章节中那样在正常模式下编译和运行应用程序 。
