Is there a non-java, cross platform way to launch the associated application for a certain file type?

Since you have noted that you are using Qt, it's worth mentioning the QDesktopServices class, and especially the openUrl(QUrl) method. It does pretty much what you've described on all platforms supported by Qt.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
