After battling with Flex 2’s DataGrid ItemRenderer for a few hours, I have finally figured out how they really work.
The Scenario Let’s say you want to have a DataGrid with a thumbnail in one of the cells. To do this you would assign the DataGridColumn an ItemRenderer. Here’s a quick and dirty MXML ItemRenderer that will work:
<?xml version="1.0" encoding="utf-8"?> <mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100%" height="100%" verticalScrollPolicy="off" horizontalScrollPolicy="off"> <mx:Image id="thumbnail" width="25" height="25"/> </HBox> Now, when the DataGrid goes to render the cell the first time, it instantiates the ItemRenderer and sets the data property to the data of the current row in the DataGrid. »
Tri-Monitors So the other day my 20.1" Widescreen Viewsonic monitor started acting funny and turning off on me (this is my 2nd one that has died), so I replaced it with a 22" Widescreen Xbrite and the new monitor rocks! I figured I would send the Viewsonic back again and have it replaced again, but I thought I would give it another shot as-is first. It seems to run fine unless I leave it on for 12-24 hours at a time so I decided to take it to my office. »
I happened to be browsing around tonight and noticed that NVIDIA has been giving away 1 prize per day for a year! Here's the catch - you need to visit the site every 7 days to see if you won or your prize will go to the next guy! Stupid! To make matters worse, only way to see if you won is to use this annoying marquee on their site!http://www.slizone.com/object/slizone_sli_giveaway.htmlSo naturally I decided to make everyone's life a little easier and pumped out a handly little Flex2 app that shows who won for the last week. »
I recently installed ubuntu 7.10 (feisty fawn) on my Compaq R3000. Since this laptop has an AMD Athlon 64 (3500+), I decided to use the AMD64 version of Ubuntu. I was able to get it installed and running well without much fussing. There were 3 main things I wanted to accomplish that did not immediately work:
Install Flash Player 9 Install NVidia Drivers and use GLX Desktop Effects Configure and use the internal wireless card I was able to get Flash Player 9 working with nspluginwrapper - this package allows you to install 32-bit Mozilla plugins on a 64-bit version of FireFox. »
Thanks to everyone who helped me test Beta 1.4.5RC1 - this pre-release was the stepping stone to version Stable 1.5.0. I was lucky to get some help testing 1.4.5RC1 from a client that gets very high traffic. After upgrading from 1.4.4 to 1.4.5RC1, his server’s mysqld process went from 20-40% down to 6%!
The system gets over 2 million WAP hits per day … The impact on the server is definitely significant. »
