Flex LinkButton Control Example
Let us follow the following steps to check usage of LinkButton control in a Flex application by creating a test application −
Step | Description |
---|---|
1 | Create a project with a name HelloWorld under a packagecom.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[
import mx.controls.Alert;
protected function clickMe_clickHandler(event:MouseEvent):void {
var linkButton:LinkButton = event.target as LinkButton;
Alert.show("LinkButton "+linkButton.id+" Clicked");
}
]]>
</fx:Script>
<s:BorderContainer width = "550" height = "500" id = "mainContainer"
styleName = "container">
<s:VGroup width = "100%" height = "100%" gap = "50" horizontalAlign = "center"
verticalAlign = "middle">
<s:Label id = "lblHeader" text = "Basic Controls Demonstration"
fontSize = "40" color = "0x777777" styleName = "heading" />
<s:Panel title = "Using LinkButton" width = "420" height = "100" >
<s:layout>
<s:HorizontalLayout paddingTop = "10" paddingLeft = "10" />
</s:layout>
<mx:LinkButton label = "Link 1" id = "clickMe"
click = "clickMe_clickHandler(event)" />
<mx:LinkButton label = "Link 2" id = "clickMe1"
click = "clickMe_clickHandler(event)" />
<mx:LinkButton label = "Link 3" id = "clickMe2"
click = "clickMe_clickHandler(event)" />
</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: [ ]
