Eclipse RCP: Actions VS Commands

Hi,

What are differences between Actions and Commands in the context of Eclipse RCP? I know that they both contribute to the menu entries, but which one is better? And why?

Of all the online resources I read, I could not get a firm understanding of the differences between both. I have not actually tried to use them, but just wanted to understand them to start with from higher level point of view.

Thanks

Just adding to VonC's excellent answer, commands might be a little overkill if your application is relatively small. They are relatively harder to setup, and they shine the most when you have multiple perspectives, editors and views.

For something simple, I would go with actions.

Agreed (+1). But I have always found Command "cleaner" in a way ;)

Specially because applications tend to grow.... I started out with actions but now I am using commands, because of the keybindings

I don't think, its a good idea to start with Actions, as Mario Ortegón said, applications tend to grow... And migrating Actions to Commands can be really painful. - But yes, Actions are easier to setup.

And remember that Action may be deprecated on later version of Eclipse. I'd suggest you to use Command from the beginning.

Do you mean I can completely abandone Action in my code?
