Add an action to both main menu & view context menu [message #329152]

Hi,

I need to create an action which will be added to both main menu & a view
context menu. In order to add the action to main menu, the action needs to
extend Action; and in order to add the action to view context menu, the
action needs to extend ActionDelegate. The same action needs to be
implemented twice. For me, it looks tedious. Is there any way such that
just implements the action once?

thanks
hao

Use a command and a handler ... then you can use org.eclipse.ui.menus to
place it in the main menu and view context menu (and most other places
as well).

Other than that, you would have to make the Action from your
ApplicationActionBarAdvisor (of which there is one per workbench window)
available to your view createPartControl(*) so you can place it in your
view context menu (assuming you are an RCP app). Or have the same class
implement both types of I*ActionDelegate needed for the 2 menus. You'll
get 2 instances of the object, but in different places.

Hi Paul,

I like the command and handler approach. Thanks a lot.

I need a little more explanation on your following comments:

>Other than that, you would have to make the Action from your
ApplicationActionBarAdvisor (of which there is one per workbench window)
available to your view createPartControl(*) so you can place it in your view
context menu (assuming you are an RCP app). Or have the same class implement
both types of I*ActionDelegate needed for the 2 menus. You'll get 2 instances
of the object, but in different places.

My question is

1. If I use command and handler approach, do I need to following the about
comments too?
2. Do you mean I need to make the reference of ApplicationActionBarAdvisor
available to my View class? Does getSite() method help for getting it in
my view class?

thanks

No, that's what you have to do if you want to use IAction based
(ApplicationActionBarAdvisor) or I*ActionDelegate based
(org.eclipse.ui.actionSets, etc) contributions. The Command+Handler
based approach simply involves creating the command and handler, and
then using org.eclipse.ui.menus/menuContribution to place the commands
in different menus.

There's no support for the first IAction based suggestion ... you would
have to code it yourself, potentially storing the needed actions in your
plugin activator (a manager, maybe) and retrieving them from your view.
