If you include and embedded font in your main Flex application where you are also using static .fxg files, the static .fxg files should pick up and use those embedded fonts. I just tried this using a global selector and it seemed to work.
Thanks for that, I was using some font swfs I compiled with the Flex 3 sdk and they didn't work but once I recompiled them with Flex 4 they did. Do you know of any plans for runtime FXG import/export? I've seen some open source projects where people load in FXG/SVG at runtime but it would be nice if it was built in to Flex.
No plans at the moment for this import functionality of .fxg. You should file a minor enhancement in the Flex bug base though and if there is enough excitement for such an addition, it might get our product manager's attention!
