GI.Gtk.Objects.Invisible

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

It is used for reliable pointer grabs and selection handling in the code for drag-and-drop.

No description available in the introspection data.

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

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

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 ()

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

set invisible [ #screen := value ]
