Qt: Safe Fonts for Cross Platform Desktop App

Just a thought: is there any resource somewhere with a list "safe-fonts" for a cross platform desktop Qt app that needs to run on windows, Mac and Linux (Ubuntu 10.* for instance).

and while we're on the subject, is there any way to "package" a font with the 开发者_StackOverflow社区executable as part of the resources and have it run seamlessly in all three platforms?

I've never tried it but I think you can use addApplicationFont to load a font from a file. The file can be part of your app's resource.
