Platform: Eclipse 3.2.0/3.2.1
Java 2 SDK 1.5.0
I'm trying to figure out the simplest and cleanest way to suppress
irrelevant menus, menu entries and toolbuttons, for an RCP
application. "Cut the clutter", so to speak.
I've looked into both product level config/code (preferred) and
runtime configuring.
The most promising candidate is defining a new perspective, but it
looks like a perspective is mostly considered with views and their
layout, and that it can add new menus, and/or menu entries. It can't
suppress/replace existing ones, unless I'm mistaken (which I actually
hope I am).
I've googled a bit and found this old bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=29179
which refer to
https://bugs.eclipse.org/bugs/show_bug.cgi?id=36967
which is said to be fixed with the introduction of the 3.0 platform.
This indicates that the functionality is in there somewhere...?
I've also googled this:
http://wiki.eclipse.org/index.php/Product_Customization#Supp ressing_An_Action
But I'm not comfortable with the solution propsed there (basically
rebuilding loaded plugin.xml files on the fly, before using them, if I
understood it correctly...).
Does anyone have any pointers or solutions, or pointers to solutions?
Thanx!

Ah, Ok. I thought bug 154099 referred to from the top of that page,
and the "Generalized OSGi Transformations" was the future stuff, and
the XSLT transformations of plugin.xml were current workarounds.

Thanx! Looks like there is some filtering possibilites here, but the
only capabilities I can disable are "Development" and "Team" (in
Window->Preferences... and then General->Capabilities).
The docs I have to study some more. Can I create activities that
suppress system commands? Or are activities meant for grouping new
commands, so that they can be disabled or enabled like "Development"
and "Team", above?

Hm... action sets seems like a promising concept. Can they be
overriden/replaced, I wonder...? Yes, they are the ones that can be
customized on a runtime/workspace basis. There the menus can be
slimmed down quite a bit. But not very useful for creating product
configurations, I'm afraid.
Thanx for the info!

Is, or is not, the "Open File..." action retargetable?
Some earlier responses on the eclipse newsgroups indicates that it is, eg.
http://dev.eclipse.org/newslists/news.eclipse.platform/msg44 590.html
http://dev.eclipse.org/newslists/news.eclipse.platform.rcp/m sg08439.html
However, it isn't listed under neither the file menu entries, nor the
global actions, in IWorkbenchActionConstants:
http://help.eclipse.org/help32/topic/org.eclipse.platform.do c.isv/reference/api/org/eclipse/ui/IWorkbenchActionConstants .html
(the wrkAdv_retarget URL says only the global actions are
retargetable).
No "Open File" entries are listed under "File Menu" either. The
newsgroup messages above are from about one year ago, and I guess that
would be the time of eclipse 3.1. But the eclipse 3.1 documentation
looks about the same as the 3.2 documentation for this.
Does anyone know?
Thanx!

Not sure this is what you're looking for, but I've found this code in KNIME
for modifying the resource navigator's context menu:
/**
* Fills the context menu with the actions contained in this group and its
* subgroups. Additionally the close project item is removed as not intended
* for the kinme projects. Note: Projects which are closed in the default
* navigator are not shown in the knime navigator any more.
*
* @param menu the context menu
*/
@Override
public void fillContextMenu(final IMenuManager menu) {
// fill the menu
super.fillContextMenu(menu);
// remove the close project item
menu.remove(CloseResourceAction.ID);
// remove some more items (this is more sophisticated, as these
// items do not have an id
for (IContributionItem item : menu.getItems()) {
if (item instanceof ActionContributionItem) {
ActionContributionItem aItem = (ActionContributionItem)item;
// remove the gointo item
if (aItem.getAction() instanceof GoIntoAction) {
menu.remove(aItem);
} else if (aItem.getAction() instanceof OpenInNewWindowAction) {
menu.remove(aItem);
}
}
}
// TODO: this is hardcoded the copy item. should be retreived more
// dynamically
String id = menu.getItems()[2].getId();
// add an open action which is not listed as the project is normally
// not openable.
menu.insertBefore(id, new Separator());
menu.insertBefore(id, new OpenKnimeProjectAction(this));
menu.insertBefore(id, new Separator());
}

Thanx for the information, but it's not quite what I'm looking for.
Adding new new toolbuttons, and menus and menu entries, are pretty
well covered by the documentation.
It's slimming down the menus provided by the framework that gives me
problems.
Ie. what do I do when our usability people ask me what a command is
for, and I reply "er... it's something eclipse put in. It has no
meaning here, but I don't know how to get rid of it", and then they
tell me that that isn't really a good answer. :-)
Another problem I have, is replacing the "Open File..." action with a
brand new action. Currently we have both the "Open File..." action
which doesn't do what we'd like it to, and an "Open XML File..."
action which does (it parses the XML into a DOM, sniffs the DOM and
decides the editor on the basis of what it finds).
So what I'm looking at are the possibilities of either losing the
standard "Open File..." action and naming the "Open Xml File.." to be
"Open File...", or changing "Open File..." using retargeting to use
the mechanism currently used by the "Open Xml File..." action.

The advanced workbench section I pointed to contains information on how
you would create your own activites and activity bindings. Then you
could disable them and make the bound-UI elements disappear.
The other things you mentioned don't work for what you want (unless I
misunderstood your question).
ActionSets allow you to create groups of actions that can be visible or
not as a group. But not everything is in ActionSets, you can't modify
existing ones only create new ones, and you can see (or not) the entire
ActionSet.
Retargetable actions are global actions (contributed by the workbench
window) whose behaviour can be overriden by individual views or editors.
But you can't control their visibility.

To repeat my platform:
Platform: Eclipse 3.2.0/3.2.1
Java 2 SDK 1.5.0
To summarize my problem here:
- I need to handle several different XML formats, all of which have
the extension .xml, with different editors for each format
- we currently have a factory which we use on input XML files to try to
determine their actual format, and create an object implementing
IEditorInput based on that
- when we get the editor input, we use it to find the id of the
editorpart class in question (we've extended the IEditorInput
interface to have an getEditorId() method)
- we call IWorkbenchPage#openEditor() with the editor input and the
appropriate editor id
To do this we've created a new editor action, which is added to the
file menu with the text "Open XML File...".
I would like that action to end up behind "Open File..." instead.
But that doesn't seem straightforward.
There is a registry from file name extension to IEditorPart, but that
won't work here. I would have needed a registry for a factory that
could return a tuple of IEditorInput and editor id, and this factory
would have needed to be used by the system "Open File..." action.
If the "Open File..." action had been retargetable, I could have
replaced it with the action currently going under the entry "Open XML
File..." (our RCP app will only ever have to open XML files, but as I
said, XML files with several formats/vocabularies/schemas).
One way that will work, is to create our own ActionBarAdviser and
populate the menus and toolbars using code. That will work, but
possibly isn't The Eclipse Way(TM)...?
Is there some possible approach I'm missing here?
Thanx!

Let's see... what I need to do, is:
- Write an implementation of the ITextContentDescriber interface
http://help.eclipse.org/help32/nftopic/org.eclipse.platform. doc.isv/reference/api/org/eclipse/core/runtime/content/IText ContentDescriber.html
- Register the class that implements ITextContentDescriber in with one
content type <extension> in plugin.xml, for each separate XML
format (described in the quoted URL above)
- Implement the ITextContentDescriber#describe() method, to look at
the contents of the file, and determine if it is one of the
supported file formats, and if it is, fill out an
IContentDescription for the format
- The IContentDescription#getContentType() method will return an
IContentType that can be used to get the correct editor
- I will need to refer to the content type ID in the editor
extensions:
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse. platform.doc.isv/reference/extension-points/org_eclipse_ui_e ditors.html
The only part that's missing is where, how, and if, IEditorInput
figures into this, when using the regular "Open File..." action...?
Thanx!

But it would be rilly-rilly-nice if they could end up in the most
recently used files list in a persistent manner.
You wouldn't happen to have a workaround for that, by any chance...? :-)
Right now I'm trying to write a persistable IPathEditorInput (I've
based open, doSave, and doSaveAs around IPathEditorInput, which is one
of the interfaces implemented by JavaFileEditorInput, and probably the
easiest one to persist), but I haven't figured out how
IPersistableElement is supposed to work yet, and still don't know if
substituting an editor's IEditorInput in the init() method will work.
Time will show.

Well, there _is_ a solution, but it isn't pretty. Something like
this:
- Create a class that extends ActionBarAdvisor
- Override the ActionBarAdvisor#fillMenuBar() method and use a
MenuManager to build _all_ of your app's menus manually (this is
what makes it not pretty in my opinion, especially when all you
want to do, is to remove a single entry from the file menu...)
- Create a class that extends WorkbenchWindowAdvisor
- Override the WorkbenchWindowAdvisor#createActionBarAdvisor()
method, and have it return an instance of your ActionBarAdvisor
class
- Create a class that extends WorkbenchAdvisor
- Override the WorkbenchAdvisor#createWorkbenchWindowAdvisor() method
to create, and return an instance of your WorkbenchWindowAdvisor
subclass
- Create a class that implements IPlatformRunnable
- In this class' run() method, call the static method
PlatformUI#createAndRunWorkbench() giving an instance of your
WorkbenchAdvisor subclass as the second argument
- Register this class with an application extension in the
org.eclipse.core.runtime.applications extension point
I may have missed a class or two that needs implementing, and there
may be more required methods, and registration of the application
extension may not be enough, but... this is hopefully enough to give
you a pointer for where to look to lose your undesired "open file"
entries...:-)

This is the core thing to implement. The rest of the classes below,
are just leading up to calling this method at the appropriate point.
Javadoc for ActionBarAdvisor:
http://help.eclipse.org/help32/nftopic/org.eclipse.platform. doc.isv/reference/api/org/eclipse/ui/application/ActionBarAd visor.html
A code fragment for the start of the fillMenuBar() method:
protected void fillMenuBar(IMenuManager menuBar)
{
super.fillMenuBar(menuBar);
IMenuManager fileMenu = new MenuManager("&File", IWorkbenchActionConstants.M_FILE);
fileMenu.add(this.newAction);
fileMenu.add(new Separator(IWorkbenchActionConstants.MB_ADDITIONS));
fileMenu.add(new Separator());
fileMenu.add(this.closeAction);
fileMenu.add(this.closeAllAction);
...
menuBar.add(fileMenu);
...
}
Ie. create a MenuManager for each menu, fill it up with the
appropriate actions, and add it to the IMenuManager given as the
method argument.
