copy

requisitionCopy

Arguments

:: (HasCallStack, MonadIO m)

=> Requisition

requisition: a Requisition

-> m Requisition

Returns: a copy of requisition

Copies a Requisition.

free

requisitionFree

Arguments

:: (HasCallStack, MonadIO m)

=> Requisition

requisition: a Requisition

-> m ()

Frees a Requisition.

new

requisitionNew

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.

Properties

height

the widget’s desired height

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

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

get requisition #height

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

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

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

get requisition #width

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

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

set requisition [ #width := value ]
