DataOpener knows how to open things in the correct application... i.e. emails in thunderbird, word documents in Word etc. etc
This is damn tricky. GnowsisAlpha had a dirty C hack done by Leo. This is clearly nasty.
- Apple Java Extensions does this on MacOSX http://developer.apple.com/documentation/Java/Reference/1.4.1/Java141API_AppleExtensions/api/com/apple/eawt/ApplicationListener.html
- Java 1.6 does this - http://download.java.net/jdk6/docs/api/java/awt/Desktop.html
- The Java Desktop Integration Classes (jdic) project does this. https://jdic.dev.java.net/
- it uses JNI and native compiled things on every platform
- Gnowsis already uses this for the trayicon support.
- MacOSX support is ropy... at best - only older versions available and only half the API.
- JConfig claims it can do all this - http://tolstoy.com/samizdat/jconfig.html
- BUT ...
- It's very "odd"
- The license might not be compatible.
- It's very old...
- Eclipse does this - maybe they have libraries?
- This has various links: http://wiki.java.net/bin/view/Main/NativeHooks
- Use Apple Java Extensions for Macosx and jdic for all other platforms.
- Linux: "gnome-open" instead of "kfmclient exec"
