Flex Gauges

[Peter Ent: Writing Flex 2 Components]: Being part of the Flex framework insures that the component is created properly and receives events at the right time. For example, when the component is created its constructor is called, but that’s not the time to make any children (the skins – needle, frame, and cover). When it is time for the children to be created, the Flex framework invokes the component’s createChildren() method. But that’s not when the component is visualized (or rendered). For that, the Flex framework invokes the component’s updateDisplayList() method.

I’m going to use the overly simple Gauge component as the example. It is simple because there is the logic to make the gauge work plus three skins. In general, that’s how components are: there is a class for the component and then skins to visualize the component. You can have many classes which make up the component, and indeed some of the Flex components do that. For the sake of brevity, I’ve limited this to a single class file.

[XML/SWF Gauge] Flash Gauges/Charting

XML/SWF Gauge is a simple, yet powerful tool to create attractive web gauges and dials from dynamic data.

Create an XML source to describe a gauge, then pass it to this tool’s flash file to generate the gauge. Type the XML source manually, or use any scripting language (PHP, Perl, ASP, CFML, etc.) to generate it automatically.

XML/SWF Gauge makes the best of both the XML and SWF worlds. XML provides flexible data generation, and Flash provides the best graphic quality.

This may not be a Flex solution, but its still a Flash solution for some charting challenges.

CustomRowColorDataGrid component

Mike Nimer’s Blog: In the last 2 projects I’ve worked on I’ve needed to change the background row color of items in the datagrid, based on values in the dataProvider.

However the flex DataGrid doesn’t allow you to set the row color this way. Turns out in order to do this you need to extend the DataGrid and override the drawRowBackground() method and put your own logic in it. Not fun at all.

So to make it easier for myself, and you, I’ve abstracted this out in a way that make the new DataGrid re-usable, and I’ve added it to my growing collection of components that you can download from here.
