Apache Flex UI Builder

Creating Flex UI with drag and drop, easy like in Flash Builder

alt text

Apache Flex UI Builder helps you to drag and drop components and also with the power of CodeMirror you can write your MXML directly in the browser, with auto complete with limited available Inspect properties, scale, change on the fly and generates mxml on every movement.

After generating mxml, you can copy and paste directly on your IDE and be more productive.

Since Flash Builder 4.7 doesn't support Design Mode, this project could help fullfill the gap left to Flex developers out there.

Components that are capable of drag and drop in current release



What's main goal?

Help Apache Flex developers keep up productivity specially the newbie developers arriving in the technology.

Why not built with Flex?

I tought on that in first place, but I wanted something more flexible that could build entirely on open technology and could run over mobile devices specially iOS devices, and some mockups could be build easly over touch devices runing directly into browser. It's hard to generate and transcode DOM elements into MXML, specially for child of N childs. Still pending on that.

Does you have plan to keep updating project?

Sure, but I've posted on github in hope of some help of your qualities that could plus the project forward.
