Introduction to Flex — Presentation at Web on the Piste

This morning I gave a presentation on “Introduction to Flex” at Web on the Piste at Queenstown, New Zealand.

It went off quite well — at least that is what I hear from the response to the presentation.

I realized that for an hour-long presentation about 20 slides is the maximum, especially when one is going to show code as well.

I’m attaching a PDF of the presentationwith this blog entry.

Also, I demoed a small RSS reader application based on Flex docs. Here is the code for that.

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">

   <mx:HTTPService id="blogService" url="{blogURI.text}" />

   <mx:Panel x="10" y="10" width="624" height="441" layout="absolute" id="blogPanel" title="{blogService.lastResult.rss.channel.title}">

      <mx:DataGrid x="10" y="40" id="blogDatagrid" width="584" dataProvider="{blogService.lastResult.rss.channel.item}" fontSize="14" height="174">

         <mx:columns>

            <mx:DataGridColumn headerText="Title" dataField="title"/>

            <mx:DataGridColumn headerText="Date" dataField="pubDate"/>

         </mx:columns>

      </mx:DataGrid>

      <mx:TextArea x="10" y="225" width="584" height="176" id="blogTextarea" fontSize="14" htmlText="{blogDatagrid.selectedItem.description}"/>

      <mx:TextInput x="10" y="10" width="466" id="blogURI">

      </mx:TextInput>

      <mx:Button x="492" y="10" label="Get RSS Feed" click="blogService.send()"/>

   </mx:Panel>

</mx:Application>
