I created a little add-on for Flash Builder 4 which gives you a "Copy Fully Qualified Name" entry to the context menu in the MXML/AS3-Editors of Flash Builder. This is especially useful if you're creating new skin classes in Flex 4 and need to know the FQCN of the skin class to reference it in the CSS file for example (oh - and for item renderers, also very useful, and for a few other things it's useful, too btw)

I was a bit lazy concerning the name for this plugin so I just called it CFQCN

To get proper result you have to point the cursor into the editor (i.e. click on an element), then right-click and choose the "Copy Fully Qualified Name" menu entry. This will try to get the FQCN of the element (in case it's an element in MXML) or the name of the topmost class (in case of AS3 file or top-level MXML elements).

Some notes:

• Members, properties and imports in AS3 (AS3 class files and Script blocks in MXML) are currently not supported
• You really need a selection on the element you want tp copy the name from, i.e. the cursor needs to be placed on the element by mouse or by keyboard

This is really the first version of the plugin and I will add more functionality over time.

To install, download the ZIP file from here, unzip it and copy the JAR file to the /plugins directory of your Flash Builder 4 / Eclipse installation and restart. That's all. Oh, and yes it's free to use. Enjoy!
