1. setTreeViewShowExpanders :: (MonadIO m, IsTreeView o) => o -> Bool -> m ()

   gi-gtk4	GI.Gtk.Objects.TreeView

   Set the value of the “show-expanders” property. When overloading is enabled, this is equivalent to

   set treeView [ #showExpanders := value ]
   

2. treeViewGetShowExpanders :: (HasCallStack, MonadIO m, IsTreeView a) => a -> m Bool

   gi-gtk4	GI.Gtk.Objects.TreeView

   Deprecated: (Since version 4.10)Use ListView or ColumnView instead

3. treeViewSetShowExpanders :: (HasCallStack, MonadIO m, IsTreeView a) => a -> Bool -> m ()

   gi-gtk4	GI.Gtk.Objects.TreeView

   Deprecated: (Since version 4.10)Use ListView or ColumnView instead

4. type WidgetShowCallback = IO ()

   gi-gtk4	GI.Gtk.Objects.Widget

   Emitted when widget is shown.

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

   gi-gtk4	GI.Gtk.Objects.Widget

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

   after widget #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.

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

   gi-gtk4	GI.Gtk.Objects.Widget

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

   on widget #show callback
   

7. widgetShow :: (HasCallStack, MonadIO m, IsWidget a) => a -> m ()

   gi-gtk4	GI.Gtk.Objects.Widget

   Deprecated: (Since version 4.10)Use widgetSetVisible instead

8. clearWidgetClassShow :: MonadIO m => WidgetClass -> m ()

   gi-gtk4	GI.Gtk.Structs.WidgetClass

   Set the value of the “show” field to Nothing. When overloading is enabled, this is equivalent to

   clear #show
   

9. getWidgetClassShow :: MonadIO m => WidgetClass -> m (Maybe WidgetClassShowFieldCallback)

   gi-gtk4	GI.Gtk.Structs.WidgetClass

   Get the value of the “show” field. When overloading is enabled, this is equivalent to

   get widgetClass #show
   

10. setWidgetClassShow :: MonadIO m => WidgetClass -> FunPtr C_WidgetClassShowFieldCallback -> m ()

    gi-gtk4	GI.Gtk.Structs.WidgetClass

    Set the value of the “show” field. When overloading is enabled, this is equivalent to

    set widgetClass [ #show := value ]
