Get classes from RCP to plugin [message #448724]

Hello !

I have created an editor as a plugin for my rcp-application.
The rcp-application is dependent on that plugin. In the context menu of that editor plugin i try to invoke some methods of the main rcp-application.
Now when i try to access classes from my rcp inside the plugin i get errors because of cycled dependencies.
My question is how can i access classes that are in my main rcp-application ?

Thanks in advance for any answer !

Option 1. Refactor your plugins so you don't have cyclic dependences!
Seriously, if you wrote the editor plugin and the RCP app plugin, create
a utilities plugin. Have the editor plugin and the RCP app plugin both
depend on the utilities plugin.

Option 2. Fool around with buddy classloading. You can set a policy on
the editor, and have the RCP app register itself with the editor plugin.
A google search should turn up some examples.

Thanks for the answer which is of course very helpful for me to get a better understanding!
But i think in my case the easiest solution would be to contribute a menu point to the editor from my rcp application.
So is it also possible to contribute a menu point in the context menu of the required editor from my rcp application ? And if it is possible how can i realize that ?

Have your editor create its context menu. Then use the
org.eclipse.ui.popupMenu extension point in your RCP app to contribute
to your editor context menu (probably viewerContribution).
