[news.eclipse.platform.rcp] Re: Radio Context Menu in View

[g_boivin_dufault@xxxxxxxxxxx (Guillaume Boivin)]

Hi,

I want to achieve the same goal. I want to add a new group in the any 
popup menu (popup menu activated on a package explorer/project explorer 
resource). In that group, one command is to choose a compilation target, 
basically you choose an element from a sub menu. From an existing Eclipse 
Plug In, the CDT  popup menu 
Build Configurations -> Set Active -> 1 Target Choice #1
                                  -> 2 Target Choice #2
                                  -> N Target Choice #N
is exactly what I would like to reproduce.

I'm using the org.eclipse.ui.menus extension. Here's my plugin.xml for 
this extension:

<extension
  point="org.eclipse.ui.menus">
  <menuContribution  
     locationURI="popup:org.eclipse.ui.popup.any?after=group.properties">
  <menu
     id="aMenuId"
     label="aLabel">
     <command
        commandId="aCommandId">
     </command>
     <dynamic
        class="aDynamicSubMenuClass"
        id="anId">
     </dynamic>
     <visibleWhen>
        <iterate>
           <adapt
              type="org.eclipse.core.resources.IResource">
                 <test
                    property="org.eclipse.core.resources.projectNature"
                    value="aCustomNature">
                 </test>
           </adapt>
        </iterate>
     </visibleWhen>
  </menu>
  </menuContribution>
</extension>

The questions I have are:

How can I had my menu so it appears at the very end of the any popup menu? 
My locationURI is: 
  locationURI="popup:org.eclipse.ui.popup.any?after=group.properties".
For the moment, my menu shows just before the properties menu but I want 
to show it as the last element of the any popup menu. I tried with 
?after=additions or ?after=group.additions but it didn't worked. 

How can I had a dynamic sub menu?
For the moment my class under the dynamic element (aDynamicSubMenuClass 
extending CompoundContributionItem) works well. I extended the 
IContributionItem[] getContributionItems() method and I'm able to generate 
the sub menu under the "aLabel" menu. Here's a simplified version of the 
getContributionItems() method:

  IContributionItem[] array = new IContributionItem[aCertainLength];
  
  for (int i=0; i<aCertainLength; i++)
  {
     array[i] = new CommandContributionItem(
 		PlatformUI.getWorkbench(),
   		aName,
   		"org.eclipse.ui.help.aboutAction",
   		null,
   		null,
   		null,
   		null,
   		aName,
   		null,
   		null,
   		CommandContributionItem.STYLE_RADIO
     );
  }
  return array

What's not working properly is that the subMenu items aren't shown as 
radio button but simply as push button. Also, I don't know what commandId 
to insert in my subMenu item (CommandContributionItem) as no command is 
intended to be called when a CommandContributionItem is selected. I 
temporarly put the existing org.eclipse.ui.help.aboutAction just to be 
able to show my subMenu.

Hope I'd been clear. If not don't hesitate to tell me because I'm not the 
only one that would benefit from a constructive answer.
