draw background for DataGrid columns

When I read Peter Ent's post about "Coloring the Background of Cells", I need to fill the column in my project, which is programmatically generated, with gradient background fill.
I didn't finish my job at the first try. After I read the post again, I found each column has to be assign a backgroundColor style before DataGrid drawColumnBackground function taking effect.
This function "drawColumnBackground" is called by drawLinesAndColumnBackgrounds function, which is called in updateDisplayList function. So I think I can update each column background by override the updateDisplayList function. I probabely need to update datagrid data as well as column background based on user action.

Reading for Custom Flex Preloader

I've read Ted's Flex 2 Preloader before I implemented a preloader class in my project.
However this class seems not working as I expected. Loading is quite glitch. I found in the code there is time interval to check status and display preloader, which slow down the process of loading animation.
After a couple of months, I retrieve this problem and found some new entries explained in detail how the preloading proceed and which class is not good to be used in preloader class.

• Flex 3 Pleloading Explained is new and has upcoming post(not posted yet) to explain the preloading in Flex;
• Custom Flex 3 Lightweight Preloader gives a very good example to build an preloader;
• Implementing A Flex 2 Custom Preloader has one Class from basic implementation of IPreloaderDisplay which is simple and detail explained.

I hope I can try to redo this preloader next week for my project.

Flex memory leaks and garbage collection

I read a series of blogs talking about memory leak and garbage collection in Flex.
It's very good resource to gain the knowledge about garbage collection in Flex.
Here is the post and following the other 4 posts from We are the heroes of Web 2.0

Good ItemRederer Article

I was used to use itemRenderer to render Datagrid and List, but most case I have to set function or event happened in Renderer and goes to it's owner to get actual action. After I saw this article, it is very good to dynamic load itemRenderer at run time. It also set function as renderer's property then. I can write function directly in the class rather than in renderer to do the job without getting the data from the owner or parent level.

The blog "Example of Feature Rich Dynamic Item Renderers in Flex 3" is from Themorphic Group.

There are also a series of articles from Peter Ent's Blog talking about itemRenderer.

Quick Note: Custom Binding in Flex

Read this Custom Binding Released! from http://www.xtyler.com/, which claims light and simple.
It also support 2-way binding, which Adobe Flex should support for binding.

Quick Note: FlowContainer

I found a couple of customized flow container in Flex. I can invest them later when my projects need.

• Flow Container @ App Division
• Flex FlowBox Container @ Tony Fendall’s Flex Blog
• 
  

Auto Complete Input Resources

There are a couple of customized components available, such as

• Adobe Exchange
• Kuwamoto
• Flex AutoComplete: Version 0.98.1 at Hillel Coren

The last one from Hillel Coren seems very nice and suitable for my project.

Input with PopUp or PopUpInput

I recently has to use a pop-up input, which behavior similar to PopUpButton. But PopUpButton name is not editable. ComboBox has the simliar thing but popup do not support UIComponent. So I create a new custom component called PopUpInput. It has the following features:

• popup can be any UIComponent;
• because of TextInput, name is editable;
• customized drop-down arrow icon;
• can extend the function to save the input text to list.

Click here for demo and source file.
However, this an alpha version of this component, some filters such as drop shadow applied on popup do not transform smoothly as same as popup itself. Also, popup does not do drop down effect when the first time is opened. Let's call it version 0.1. I will update it later as I finish my Java study.
