Some code to manage preferencePage with an extension point (as in Eclipse 3).
This new release is updated to mix both E3 and E4 preference pages. So you can define pure E4 preference pages in a plug-in, and launch your plugin either in a pure E4 application or in a compatibility runtime.
You can get some explainations on my blog
If you want to add the 'Window -> Preferences' menu automatically in your pure e4 application, use the com.opcoach.e4.preferences.mainmenu plugin fragment in your launch configuration. To get the menu, it assumes that your main menu has the regular ID : 'org.eclipse.ui.main.menu'.
If you are running with the compatibility layer, do not use the com.opcoach.e4.preferences.mainmenu plugin fragment, and prefer to add the Preference Action in your ActionBarAdvisor.
This project is available on this p2 repository : https://www.opcoach.com/repository/latest (use the com.opcoach.e4.preferences.feature.feature.group)
