Flex BorderContainer Example
Let us follow the following steps to check usage of BorderContainer in a Flex application by creating a test application:
| Step | Description |
|---|---|
| 1 | Create a project with a name HelloWorld under a package com.tutorialspoint.client as explained in the Flex - Create Application chapter. |
| 2 | Modify HelloWorld.mxml as explained below. Keep rest of the files unchanged. |
| 3 | Compile and run the application to make sure business logic is working as per the requirements. |
Following is the content of the modified mxml file src/com.tutorialspoint/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/tutorialspoint/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);
}

<s:HGroup verticalAlign="middle">

<s:CheckBox id="chkShadow" selected="false"/>
</s:HGroup>
<s:Button label="Apply Properties"
click="applyBorderContainerProperties()"/>

<s:BorderContainer id="borderContainer" width="200"
backgroundColor="0xff99ff">
</s:BorderContainer>
</s:HGroup>
</s:Panel>
</s:VGroup>
</s:BorderContainer>
</s:Application>
Once you are ready with all the changes done, let us compile and run the application in normal mode as we did in Flex - Create Application chapter. If everything is fine with your application, this will produce following result: [ Try it online ]
