Creating a custom component using the Definition tag in Flex 4

by Peter deHaan on November 6, 2009

in beta2

In a previous example, “Creating a custom component using the Component tag in Flex 4″, we saw how you could create a simple, inline custom component in Flex 4 using the Component tag and className property and then instantiating new instances using ActionScript and MXML.

The following example shows how you can create a new custom component using the Definition tag in Flex 4.

Full code after the jump.

The following example(s) require Flash Player 10 and the Adobe Flex 4 SDK. To download the Adobe Flash Builder 4 beta, check out the Adobe Flash Builder 4 page on the Adobe Labs site. To download the latest build of the Flex 4 SDK, see http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4. For instructions on using the beta Flex 4 SDK in Flex Builder 3, see "Using the beta Flex 4 SDK in Flex Builder 3".

This entry is based on a beta version of the Flex 4 SDK and therefore is very likely to change as development of the Flex SDK continues. The API can (and will) change causing examples to possibly not compile in newer versions of the Flex 4 SDK.
