1. type MenuitemShowToUserCallback = Word32 -> IO ()

   gi-dbusmenu	GI.Dbusmenu.Objects.Menuitem

   Signaled when the application would like the visualization of this menu item shown to the user. This usually requires going over the bus to get it done.

2. afterMenuitemAboutToShow :: (IsMenuitem a, MonadIO m) => a -> ((?self :: a) => MenuitemAboutToShowCallback) -> m SignalHandlerId

   gi-dbusmenu	GI.Dbusmenu.Objects.Menuitem

   Connect a signal handler for the aboutToShow signal, to be run after the default handler. When overloading is enabled, this is equivalent to

   after menuitem #aboutToShow callback
   

   By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

3. afterMenuitemShowToUser :: (IsMenuitem a, MonadIO m) => a -> ((?self :: a) => MenuitemShowToUserCallback) -> m SignalHandlerId

   gi-dbusmenu	GI.Dbusmenu.Objects.Menuitem

   Connect a signal handler for the showToUser signal, to be run after the default handler. When overloading is enabled, this is equivalent to

   after menuitem #showToUser callback
   

   By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

4. menuitemSendAboutToShow :: (HasCallStack, MonadIO m, IsMenuitem a) => a -> Ptr () -> Ptr () -> m ()

   gi-dbusmenu	GI.Dbusmenu.Objects.Menuitem

   This function is used to send the even that the submenu of this item is about to be shown. Callers to this event should delay showing the menu until their callback is called if possible.

5. menuitemShowToUser :: (HasCallStack, MonadIO m, IsMenuitem a) => a -> Word32 -> m ()

   gi-dbusmenu	GI.Dbusmenu.Objects.Menuitem

   Signals that this menu item should be shown to the user. If this is server side the server will then take it and send it over the bus.

6. onMenuitemAboutToShow :: (IsMenuitem a, MonadIO m) => a -> ((?self :: a) => MenuitemAboutToShowCallback) -> m SignalHandlerId

   gi-dbusmenu	GI.Dbusmenu.Objects.Menuitem

   Connect a signal handler for the aboutToShow signal, to be run before the default handler. When overloading is enabled, this is equivalent to

   on menuitem #aboutToShow callback
   

7. onMenuitemShowToUser :: (IsMenuitem a, MonadIO m) => a -> ((?self :: a) => MenuitemShowToUserCallback) -> m SignalHandlerId

   gi-dbusmenu	GI.Dbusmenu.Objects.Menuitem

   Connect a signal handler for the showToUser signal, to be run before the default handler. When overloading is enabled, this is equivalent to

   on menuitem #showToUser callback
   

8. type CompletionShowCallback = IO ()

   gi-gtksource5	GI.GtkSource.Objects.Completion

   The "show" signal is emitted when the completion window should be shown.

9. afterCompletionShow :: (IsCompletion a, MonadIO m) => a -> ((?self :: a) => CompletionShowCallback) -> m SignalHandlerId

   gi-gtksource5	GI.GtkSource.Objects.Completion

   Connect a signal handler for the show signal, to be run after the default handler. When overloading is enabled, this is equivalent to

   after completion #show callback
   

   By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

10. completionShow :: (HasCallStack, MonadIO m, IsCompletion a) => a -> m ()

    gi-gtksource5	GI.GtkSource.Objects.Completion

    Emits the "show" signal. When the "show" signal is emitted, the completion window will be displayed if there are any results available.
