Description

A Requisition-struct represents the desired size of a widget. See [GtkWidget’s geometry management section][geometry-management] for more information.

Synopsis

newtype Requisition = Requisition (ManagedPtr Requisition)
newZeroRequisition :: MonadIO m => m Requisition
requisitionCopy :: (HasCallStack, MonadIO m) => Requisition -> m Requisition
requisitionFree :: (HasCallStack, MonadIO m) => Requisition -> m ()
requisitionNew :: (HasCallStack, MonadIO m) => m Requisition
getRequisitionHeight :: MonadIO m => Requisition -> m Int32
setRequisitionHeight :: MonadIO m => Requisition -> Int32 -> m ()
getRequisitionWidth :: MonadIO m => Requisition -> m Int32
setRequisitionWidth :: MonadIO m => Requisition -> Int32 -> m ()

newZeroRequisition :: MonadIO m => m Requisition Source #

Construct a Requisition struct initialized to zero.

Methods

Overloaded methods

copy

requisitionCopy Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Requisition	`requisition`: a `Requisition`
-> m Requisition	Returns: a copy of `requisition`

Copies a Requisition.

free

requisitionFree Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Requisition	`requisition`: a `Requisition`
-> m ()

Frees a Requisition.

new

requisitionNew Source #

Arguments

:: (HasCallStack, MonadIO m)
=> m Requisition	Returns: a new empty `Requisition`. The newly allocated `Requisition` should be freed with `requisitionFree`.

Allocates a new Requisition-struct and initializes its elements to zero.

Since: 3.0

Properties

height

the widget’s desired height

getRequisitionHeight :: MonadIO m => Requisition -> m Int32 Source #

Get the value of the “height” field. When overloading is enabled, this is equivalent to

get requisition #height

setRequisitionHeight :: MonadIO m => Requisition -> Int32 -> m () Source #

Set the value of the “height” field. When overloading is enabled, this is equivalent to

set requisition [ #height := value ]

width

the widget’s desired width

getRequisitionWidth :: MonadIO m => Requisition -> m Int32 Source #

Get the value of the “width” field. When overloading is enabled, this is equivalent to

get requisition #width

setRequisitionWidth :: MonadIO m => Requisition -> Int32 -> m () Source #

Set the value of the “width” field. When overloading is enabled, this is equivalent to

set requisition [ #width := value ]
