- holdNotReadyDynamicWidget :: (MonadRunGtk m, MonadHold t m, Reflex t) => Event t (Dynamic t Widget) -> m (Dynamic t Widget)
- notReadyWidget :: IO Widget
Documentation
holdNotReadyWidget :: (MonadRunGtk m, MonadHold t m) => Event t Widget -> m (Dynamic t Widget) Source #
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) Source #
A variant of holdNotReadyWidget where Widgets aren't replaced
directly, but instead different Dynamic t Widget
notReadyWidget :: IO Widget Source #
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.
