fxSpy 1.4
Inspect, edit and monitor your Flex application's components properties and styles.
This is a port of the original version to Flex 4.x SDKs (works as well on 2/3 or in compatibility mode, has been tested with custom PopPupManager where all the display list and popups belong to a particular container too).
Check out the live demo (in the application, click the flexSpy button on the top-right corner)
fxSpy allow you to inspect and dynamically change most properties and styles of the visual components in your Flex application. You can - for example - try out a specific width or a background color for your component before changing it in your code.
To install it in your application, follow the Installation Instructions.
The code is released under WTFPL
