Hi!
1. I have some.domain.SomeDiagramEditor editor extending org.eclipse.gmf.runtime.diagram.ui.resources.editor.parts.DiagramDocumentEditor.
If I click RMB on some node on diagram, then default popup appears. For a specific node I would like to hide all existing items in this popup menu and show only my contributed popup item. I use org.eclipse.ui.menus extension point to contribute my custom action. Should I use org.eclipse.gmf.runtime.common.ui.services.action.contributionItemProviders extension point and popupPredefiniedItem element for every already contributed action? What if some new plugin will contribute some new item, that I didn't hide this way? - it will be displayed.

2. I use org.eclipse.ui.commands extension point to define my custom action. MyActionHandler extends org.eclipse.core.commands.AbstractHandler. I would like to make popup action enabled depending on a selected node state. org.eclipse.core.commands.AbstractHandler has

public void setEnabled(Object evaluationContext)

method, but it isn't invoked when poup shows at first time.
What is the correct way to do this?

Hi,

yeah it's a bit tricky. Here my code, thinks its explains itself.
If you have questions, just ask.

<plugin>
   <extension
      point="org.eclipse.ui.commands">
      <command
         defaultHandler="de.woep.blub.custom.generator.GenerateCodeAction"
         id="de.woep.blub.generateCodeCommand"
         name="Sample Command">
      </command>
   </extension>
   <extension
      point="org.eclipse.ui.menus">
      <menuContribution
         locationURI=
         "popup:org.eclipse.gmf.runtime.diagram.ui.DiagramEditorContextMenu">
         <menu
            id="org.eclipse.gmf.runtime.diagram.ui.DiagramEditorContextMenu.generateCodeMenu"
            label="My perfect menu">
            <command
               id="org.eclipse.gmf.runtime.diagram.ui.DiagramEditorContextMenu.generateCode"
               commandId="de.woep.blub.generateCodeCommand"
               label="Generate code"
               tooltip="Generates code from a model file">
              </command>
           </menu>
        </menuContribution>
     </extension>
  </plugin>

Thank you for response! Smile

Actually, above code contributes new submenu "My perfect menu" to existing popup.
What i want to achieve is to disable all items in existing

popup:org.eclipse.gmf.runtime.diagram.ui.DiagramEditorContextMenu

popup except my own contributions, if my context is set. I know that I can remove every item using

org.eclipse.gmf.runtime.common.ui.services.action.contributionItemProviders

extension point and popupPredefiniedItem element, and contribute my own items, but different plugins can contribute different menu items and I don't have list of all contributed menu items.

I set context using
