GI.Gtk.Objects.CellRendererSpin
Description
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.

toCellRendererSpin :: (MonadIO m, IsCellRendererSpin o) => o -> m CellRendererSpin Source #
Cast to CellRendererSpin, for types for which this is known to be safe. For general casts, use castTo.
noCellRendererSpin :: Maybe CellRendererSpin Source #
A convenience alias for Nothing :: Maybe CellRendererSpin.
Methods
new
Arguments
| :: (HasCallStack, MonadIO m) | |
| => m CellRendererSpin | Returns: a new |
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 () Source #
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) Source #
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) Source #
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 () Source #
Set the value of the “adjustment” property.
When overloading is enabled, this is equivalent to
setcellRendererSpin [ #adjustment:=value ]
climbRate
The acceleration rate when you hold down a button.
Since: 2.10
constructCellRendererSpinClimbRate :: IsCellRendererSpin o => Double -> IO (GValueConstruct o) Source #
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 Source #
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 () Source #
Set the value of the “climb-rate” property.
When overloading is enabled, this is equivalent to
setcellRendererSpin [ #climbRate:=value ]
digits
The number of decimal places to display.
Since: 2.10
constructCellRendererSpinDigits :: IsCellRendererSpin o => Word32 -> IO (GValueConstruct o) Source #
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 Source #
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 () Source #
Set the value of the “digits” property.
When overloading is enabled, this is equivalent to
setcellRendererSpin [ #digits:=value ]
