Red5 Chat in Flex 4 – Gumbo

Een simple chat aplicatie met red5 en flex4 sdk with flashdevelop.. Het is leuk om hiermee te starten en verder ontwikkellen tot een uitgebeide chat applicatie…

hier is de mxml code:
<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”
minWidth=”1024″ minHeight=”768″
initialize=”TextSO()”>

<!– Messaging Declarations –>

<!– UI Declarations –>

<s:Panel title=”Simple Flex Chat”>
<mx:TextArea id=”textAreaChat” valueCommit=”textAreaChat.verticalScrollPosition=textAreaChat.maxVerticalScrollPosition”
width=”385″ height=”220″ y=”20″
>
</mx:TextArea>
<s:TextInput id=”textInput” width=”385″  />
<mx:ControlBar horizontalAlign=”center” width=”385″>
<s:Button id=”button” label=”Send” click=”sendMsg(event)” />
</mx:ControlBar>
</s:Panel>
