GI.Gtk.Objects.Invisible

Contents

Description

The Invisible widget is used internally in GTK+, and is probably not very useful for application developers.

constructInvisibleScreen :: (IsInvisible o, IsScreen a) => a -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “screen” property. This is rarely needed directly, but it is used by new.

getInvisibleScreen :: (MonadIO m, IsInvisible o) => o -> m Screen Source #

Get the value of the “screen” property. When overloading is enabled, this is equivalent to

get invisible #screen

setInvisibleScreen :: (MonadIO m, IsInvisible o, IsScreen a) => o -> a -> m () Source #

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

set invisible [ #screen := value ]
