RCP Testing -- Contribution Identities [message #1699458]

Hi all,

How can I assign an identity to a toolbar button that has been added using extension points, i.e. by a menu contribution like in the following example?

   <extension
         point="org.eclipse.ui.menus">
       <menuContribution
            allPopups="false"
            locationURI="toolbar:org.eclipse.ui.main.toolbar">
         <toolbar
               id="net.morcate.mypackage.toolbar"
               label="Neighborhood Toolbar">
            <command
                  commandId="org.eclipse.ui.views.showView"
                  icon="icons/primary.png"
                  id="net.morcate.mypackage.showView"
                  label="Neighborhood"
                  style="push"
                  tooltip="Show Neighborhood">
               <parameter
                     name="org.eclipse.ui.views.showView.viewId"
                     value="net.morcate.mypackage.viewer">
               </parameter>
            </command>
         </toolbar>
      </menuContribution>
   </extension>

Thank you very much

I'm not understanding what you're looking for as you have it in your example: your <command> has an id "net.morcate.mypackage.showView". So you can do an "after=net.morcate.mypackage.showView" in your location URIs.

Thanks Brian for your reply.

The previous XML fragment will 'produce' a button in the main toolbar of my application. My problem is that the button doesn't have an id that I can use to find it later when running my SWTBot tests. At the moment, I just go through the buttons checking the tooltip text. But this seems too brittle to me. I would prefer to be able to assign an id as I can do with other widget that I build programmatically.

Thank you again

Hmm, I see your point. I think you'll need to write an SWTBot Finder that knows how to traverse E4-level concepts: the org.eclipse.ui.menus extension point is used to populate E4-level toolbars.

org.eclipse.swtbot.e4.finder has a MenuFinder and ContextMenuFinder but they are actually SWT-based rather than E4-based, so they're not perfect exemplars to follow. Each of the E4 UI Elements (MUIElement) generally have a corresponding SWT widget that you can obtain using MUIElement#getWidget(). Each of these widgets has a back pointer to the MUIElement using the widget's data dictionary using the key AbstractPartRenderer.OWNING_ME = "modelElement".

So you can get the current MWindow, verify it's a MTrimmedWindow, and check its MTrimmedWindow > getTrimBars(). And then iterate over the contents looking for MHandledItems whose elementId matches the "id" or whose command matches the "commandId" (whichever you want).

And then contribute it back to SWTBot
