any references to command handler syntax? [message #493796] Wed, 28 October 2009 02:47 Go to next message

I've looked at various e4 demos, and am trying to convert my own project to work under e4. I'm unclear, however, how one figures out the allowed parameters to a command handler execute() method. Various objects registered as handlers take different numbers and types of parameters. I understand the idea of dependency injection, I'm just trying to get some sense of what sorts of objects these execute methods are allowed to use, or a reference to any document anywhere that might define them. Any pointers to documentation? (the wiki page on Commands/Handlers is early enough and high enough that it's got no details of use in actually building myself a working app.)

Any pointers or suggestions would be GREATLY appreciated!

This hasn't been defined yet, as we're still working on the story.

Some of the main variables that can be used are already captured in

You can use anything that can come out of your IEclipseContext ... right now that means OSGi services, some of the new e4 services (like org.eclipse.e4.core.commands.ECommandService), and framework wiring like "selection" and "activePart" ... although the meaning of activePart in an e4 RCP app is not clear.

We will be documenting the information that the framework can provide, it's just not done at the moment.
