1. afterWidgetMapEvent :: (IsWidget a, MonadIO m) => a -> ((?self :: a) => WidgetMapEventCallback) -> m SignalHandlerId

   gi-gtk3	GI.Gtk.Objects.Widget

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

   after widget #mapEvent 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.

2. afterWidgetUnmap :: (IsWidget a, MonadIO m) => a -> ((?self :: a) => WidgetUnmapCallback) -> m SignalHandlerId

   gi-gtk3	GI.Gtk.Objects.Widget

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

   after widget #unmap 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. afterWidgetUnmapEvent :: (IsWidget a, MonadIO m) => a -> ((?self :: a) => WidgetUnmapEventCallback) -> m SignalHandlerId

   gi-gtk3	GI.Gtk.Objects.Widget

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

   after widget #unmapEvent 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. onWidgetMap :: (IsWidget a, MonadIO m) => a -> ((?self :: a) => WidgetMapCallback) -> m SignalHandlerId

   gi-gtk3	GI.Gtk.Objects.Widget

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

   on widget #map callback
   

5. onWidgetMapEvent :: (IsWidget a, MonadIO m) => a -> ((?self :: a) => WidgetMapEventCallback) -> m SignalHandlerId

   gi-gtk3	GI.Gtk.Objects.Widget

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

   on widget #mapEvent callback
   

6. onWidgetUnmap :: (IsWidget a, MonadIO m) => a -> ((?self :: a) => WidgetUnmapCallback) -> m SignalHandlerId

   gi-gtk3	GI.Gtk.Objects.Widget

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

   on widget #unmap callback
   

7. onWidgetUnmapEvent :: (IsWidget a, MonadIO m) => a -> ((?self :: a) => WidgetUnmapEventCallback) -> m SignalHandlerId

   gi-gtk3	GI.Gtk.Objects.Widget

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

   on widget #unmapEvent callback
   

8. widgetGetFontMap :: (HasCallStack, MonadIO m, IsWidget a) => a -> m (Maybe FontMap)

   gi-gtk3	GI.Gtk.Objects.Widget

   Gets the font map that has been set with widgetSetFontMap. Since: 3.18

9. widgetGetMapped :: (HasCallStack, MonadIO m, IsWidget a) => a -> m Bool

   gi-gtk3	GI.Gtk.Objects.Widget

   Whether the widget is mapped. Since: 2.20

10. widgetMap :: (HasCallStack, MonadIO m, IsWidget a) => a -> m ()

    gi-gtk3	GI.Gtk.Objects.Widget

    This function is only for use in widget implementations. Causes a widget to be mapped if it isn’t already.
