"Run" menu is placed before other menus in an Eclipse RCP IDE project

I have developed a IDE for a custom language in Eclipse 3 for RCP and RAP developers. Therefore I used IDE plug-ins wherever possible and applicable. This week I was busy migrating the application to Eclipse e4 (with compatibility layer) with Eclipse for RCP and RAP developers 2021-6. Everything works nearly fine so far.

The one thing i cannot figure out is how I can place the "run" menu where I want. It is placed as first menu in the menu bar.

Another strange thing by the way is that if I use Eclipse 2020-6 instead of 2021-6 as development environment, also the search menu is at the wrong position.

The problem is that the run and search menus come from an IDE plug-in and they are implemented as actions and therefore I cannot specify any order in terms of menus. For all other menus I defined appropriate menuContibutions, commands and handlers. For the latter, I can decide where each menu should be placed with the help of plugin.xml by specifying ?before= or ?after=.

I did a search over stackoverflow issues that have to do with adding menus, reorderung menus, mixing actions with commands and handlers and so on but I could not find a solution how I could place the run menu where I want.

I hoped that there would be something like an ID that I can use to specify as ?before= or ?after= in plugin.xml but I think this will not work with actions.

Can anyone give me a hint how I could place all menus in the desired order? Or is this simply impossible when mixing actions and commands+handlers? Is there any actions-wrapping functionality in order for me to specify ?before= or ?after= in my menuContibutions in plugin.xml?

Solution

  • If you mean the Run menu added by the org.eclipse.debug.ui plug-in this is created using and action set:

       <extension point="org.eclipse.ui.actionSets">
        <actionSet
            label="%BreakpointActionSet.label"
            visible="false"
            id="org.eclipse.debug.ui.breakpointActionSet">
         <menu
               label="%RunMenu.label"
               path="additions"
               id="org.eclipse.ui.run">

    which is adding the Run menu at the position additions in the main menu.

    The standard main menu created by org.eclipse.ui.internal.ide.WorkbenchActionBuilder creates the main menu like this:

    @Override
protected void fillMenuBar(IMenuManager menuBar) {
    menuBar.add(createFileMenu());
    menuBar.add(createEditMenu());
    menuBar.add(createNavigateMenu());
    menuBar.add(createProjectMenu());

    // This line creates the 'additions' position
    menuBar.add(new GroupMarker(IWorkbenchActionConstants.MB_ADDITIONS));

    menuBar.add(createWindowMenu());
    menuBar.add(createHelpMenu());
}
