Hello,
is it possible to execute an Action programmatically as you shown for Commands?

2011-09-18T12:09:26.047+05:30

I'm developing a plugin that uses the standard project explorer view and
I want to replace the default "delete" handler. My plugim.xml file
contains the following handler:

The handler works correctly :
1- in the Edit/Delete menu
2- or when I press the Delete key (via key binding)

However, when I right click on a resource in Project Explorer and click
on the Delete popup menu item, my handler is ignored and the default
handler is called. Why is my handler ignored when the delete command is
called from the context menu of the project explorer and works correctly
from menu and key binding?

Any help will be appreciated. Thank You.

@Prakash-

Thanks for the feedback! Actually, last night after asking you this, I went ahead and overrode makeActions() in ActionBarAdvisor:

protected void makeActions(IWorkbenchWindow window) {
super.makeActions(window);
register(ActionFactory.UNDO.create(window));
}

So while the UNDO command is not entirely declarative (in plugin.xml), I still don't *need* to use fillMenuBar() to make my menus, so I can follow the examples in your tutorial. I just need to remember to use makeActions() when dealing w/ RetargetActions.

Thanks for the explanation and the link to the bug.

@Anon,

There is no way to go away without registering. It should be possible when this gets fixed: https://bugs.eclipse.org/bugs/show_bug.cgi?id=270007

I'm also interested in finding out more about retargetable actions using the new commands framework.

I've tried converting all my menus using the new commands framework, and now my undo action is not working.

OLD WAY (in fillMenuBar):
IAction action = ActionFactory.UNDO.create(window);
menuManager.add(action);
getActionBarConfigurer().registerGlobalAction(action);

NEW WAY (in plugin.xml):
<command
commandId="org.eclipse.ui.edit.undo"
id="undo"
label="Undo"
style="push">
</command>

Is there a way to emulate registerGlobalAction() declaratively?

I've found a few old posts with people running into the same problem, but haven't found any answers, and google isn't turning up anything.

Great blog post BTW (very useful)!

@Kos,
Yes you can use commands in popup menus. You need to use the o.e.ui.menus and the URI should start with "popup:" See: http://wiki.eclipse.org/Menu_Contributions

Hello!

Thanks for writing the good explanation.

I have a question: Can I use the command framework with extension points which expect Actions? For example, can I somehow contribute a Command to an extension point like org.eclipse.ui.PopupMenus ?

This one seems useful as it gives the possibility to add a popup menu to an object regardless of where it is displayed.

Best regards,

Hi Prakash,

Did you write the 2 posts you mentionned in the last comment?

What are the subjects?

Is the copy/paste/undo/redo is one of this subject?

Thanks,

Short answer is yes, the long answer will be posted as a separate tip :-)

Hi,

Can commands be used to override the Copy/Paste/Delete/Rename/... commands (retargetable actions)?

If yes, how it works?

Thanks

Hi,

I relation to this: "As you see, in the actions we would just use only one extension point, instead of the four which we have used now."

You could have done this with two extensions points by using the default handler and the icons in the menucontributin.

Please see here for an explaination: http://www.vogella.de/articles/RichClientPlatform/article.html#commands
