Description

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.

Synopsis

newtype Invisible = Invisible (ManagedPtr Invisible)
class GObject o => IsInvisible o
toInvisible :: (MonadIO m, IsInvisible o) => o -> m Invisible
noInvisible :: Maybe Invisible
invisibleGetScreen :: (HasCallStack, MonadIO m, IsInvisible a) => a -> m Screen
invisibleNew :: (HasCallStack, MonadIO m) => m Invisible
invisibleNewForScreen :: (HasCallStack, MonadIO m, IsScreen a) => a -> m Invisible
invisibleSetScreen :: (HasCallStack, MonadIO m, IsInvisible a, IsScreen b) => a -> b -> m ()
constructInvisibleScreen :: (IsInvisible o, IsScreen a) => a -> IO (GValueConstruct o)
getInvisibleScreen :: (MonadIO m, IsInvisible o) => o -> m Screen
setInvisibleScreen :: (MonadIO m, IsInvisible o, IsScreen a) => o -> a -> m ()

toInvisible :: (MonadIO m, IsInvisible o) => o -> m Invisible Source #

noInvisible :: Maybe Invisible Source #

A convenience alias for Nothing :: Maybe Invisible.

Methods

getScreen

invisibleGetScreen Source #

Arguments

:: (HasCallStack, MonadIO m, IsInvisible a)
=> a	`invisible`: a `Invisible`.
-> m Screen	Returns: the associated `Screen`.

Returns the Screen object associated with invisible

Since: 2.2

new

invisibleNew Source #

Arguments

:: (HasCallStack, MonadIO m)
=> m Invisible	Returns: a new `Invisible`.

Creates a new Invisible.

newForScreen

invisibleNewForScreen Source #

Arguments

:: (HasCallStack, MonadIO m, IsScreen a)
=> a	`screen`: a `Screen` which identifies on which the new `Invisible` will be created.
-> m Invisible	Returns: a newly created `Invisible` object

Creates a new Invisible object for a specified screen

Since: 2.2

setScreen

invisibleSetScreen Source #

Arguments

:: (HasCallStack, MonadIO m, IsInvisible a, IsScreen b)
=> a	`invisible`: a `Invisible`.
-> b	`screen`: a `Screen`.
-> m ()

Sets the Screen where the Invisible object will be displayed.

Since: 2.2

No description available in the introspection data.

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 ]
