holdNotReadyWidget :: (MonadRunGtk m, MonadHold t m) => Event t Widget -> m (Dynamic t Widget)

Hold an Event firing Widgets in a Dynamic, automatically using a notReadyWidget as the initial value.

holdNotReadyDynamicWidget :: (MonadRunGtk m, MonadHold t m, Reflex t) => Event t (Dynamic t Widget) -> m (Dynamic t Widget)

A variant of holdNotReadyWidget where Widgets aren't replaced directly, but instead different Dynamic t Widgets are switched in.

notReadyWidget :: IO Widget

A widget appropriate for displaying in place of widgets that aren't available yet, e.g. as replacement for widgets that aren't available until post-build time.

The current implementation returns a Spinner that has been started (spinnerStart).

Note that the widget is not widgetShown in this function. If you want the Widget to be actually shown, you should call widgetShow explicitly on it.
