Where is the right place to instantiate the ActionPopup


Probably define an actionbar for this case.


  • Invokation
    • Right click on workbench row invokes ActionPopup:
      • BrowserSubApp.registerSubAppEventsHandlers()
    • Click on a button in FileUploadField can invoke ActionPopup - probably needs to point to which one it wants.
    • Shell has a method - or UIContext, so you can get it from anywhere? openActionPopup("name") (could take the name of an actionpopup or of an actionbar)
  •  UI

    • ActionPopup should float above all UI.

    • ActionPopup should be positioned at mouse (and fully onscreen)

    • It should go away if

      • Click on menu Item

      • or click mouse (It could display a modal curtain while it is open)

      • or timeout

      • or switch apps, or subapps, or open an Overlay, or open a shellapp,

      • Does Vaadin have concept of foccused item - could this help us know when the popup should close?

  • Generalize UI menu

    • Actionbar becomes ActionMenu

    • Css must get tuned.

    • Actionbar uses ActionMenu

    • Actionpopup uses ActionMenu

    • ActionPopup takes an ActionMenu definition

    • can be build from configuration

    • can be construct manually.


Right Clicking





Implement a host for the ActionPopup

Shell has a server component which is the actionpopup? You can hide and show it + position it.

  • TreeViewImpl.addItemClickListener > presenterOnRightClick()
  • TreeViewImpl.presenterOnRightClick() >
  • ContentPresenter.onRightClick() > fires ItemRightClickedEvent() on SubAppEventBus.
  • BrowserSubApp
