GI.Gtk.Objects.CellRendererSpin

CellRendererSpin renders text in a cell like CellRendererText from which it is derived. But while CellRendererText offers a simple entry to edit the text, CellRendererSpin offers a SpinButton widget. Of course, that means that the text has to be parseable as a floating point number.

The range of the spinbutton is taken from the adjustment property of the cell renderer, which can be set explicitly or mapped to a column in the tree model, like all properties of cell renders. CellRendererSpin also has properties for the CellRendererSpin:climb-rate and the number of CellRendererSpin:digits to display. Other SpinButton properties can be set in a handler for the CellRenderer::editing-started signal.

The CellRendererSpin cell renderer was added in GTK+ 2.10.

class (GObject o, IsDescendantOf CellRendererSpin o) => IsCellRendererSpin o

Type class for types which can be safely cast to CellRendererSpin, for instance with toCellRendererSpin.

Instances

(GObject o, IsDescendantOf CellRendererSpin o) => IsCellRendererSpin o

Defined in GI.Gtk.Objects.CellRendererSpin

toCellRendererSpin :: (MonadIO m, IsCellRendererSpin o) => o -> m CellRendererSpin

Cast to CellRendererSpin, for types for which this is known to be safe. For general casts, use castTo.

noCellRendererSpin :: Maybe CellRendererSpin

A convenience alias for Nothing :: Maybe CellRendererSpin.

Methods

new

cellRendererSpinNew

Arguments

:: (HasCallStack, MonadIO m)

=> m CellRendererSpin

Returns: a new CellRendererSpin

Creates a new CellRendererSpin.

Since: 2.10

Properties

adjustment

The adjustment that holds the value of the spinbutton. This must be non-Nothing for the cell renderer to be editable.

Since: 2.10

clearCellRendererSpinAdjustment :: (MonadIO m, IsCellRendererSpin o) => o -> m ()

Set the value of the “adjustment” property to Nothing. When overloading is enabled, this is equivalent to

clear #adjustment

constructCellRendererSpinAdjustment :: (IsCellRendererSpin o, IsAdjustment a) => a -> IO (GValueConstruct o)

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

getCellRendererSpinAdjustment :: (MonadIO m, IsCellRendererSpin o) => o -> m (Maybe Adjustment)

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

get cellRendererSpin #adjustment

setCellRendererSpinAdjustment :: (MonadIO m, IsCellRendererSpin o, IsAdjustment a) => o -> a -> m ()

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

set cellRendererSpin [ #adjustment := value ]

climbRate

The acceleration rate when you hold down a button.

Since: 2.10

constructCellRendererSpinClimbRate :: IsCellRendererSpin o => Double -> IO (GValueConstruct o)

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

getCellRendererSpinClimbRate :: (MonadIO m, IsCellRendererSpin o) => o -> m Double

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

get cellRendererSpin #climbRate

setCellRendererSpinClimbRate :: (MonadIO m, IsCellRendererSpin o) => o -> Double -> m ()

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

set cellRendererSpin [ #climbRate := value ]

digits

The number of decimal places to display.

Since: 2.10

constructCellRendererSpinDigits :: IsCellRendererSpin o => Word32 -> IO (GValueConstruct o)

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

getCellRendererSpinDigits :: (MonadIO m, IsCellRendererSpin o) => o -> m Word32

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

get cellRendererSpin #digits

setCellRendererSpinDigits :: (MonadIO m, IsCellRendererSpin o) => o -> Word32 -> m ()

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

set cellRendererSpin [ #digits := value ]
