GI.Gtk.Objects.HScale

The HScale widget is used to allow the user to select a value using a horizontal slider. To create one, use hScaleNewWithRange.

The position to show the current value, and the number of decimal places shown can be set using the parent Scale class’s functions.

GtkHScale has been deprecated, use Scale instead.

Exported types

newtype HScale

Memory-managed wrapper type.

Constructors

HScale (ManagedPtr HScale)

Instances

Eq HScale

Defined in GI.Gtk.Objects.HScale

Methods

(==) :: HScale -> HScale -> Bool

(/=) :: HScale -> HScale -> Bool

IsGValue HScale

Convert HScale to and from GValue with toGValue and fromGValue.

Defined in GI.Gtk.Objects.HScale

Methods

toGValue :: HScale -> IO GValue

fromGValue :: GValue -> IO HScale

Methods

gobjectType :: IO GType

HasParentTypes HScale

type ParentTypes HScale

Defined in GI.Gtk.Objects.HScale

type ParentTypes HScale = '[Scale, Range, Widget, Object, ImplementorIface, Buildable, Orientable]

class (GObject o, IsDescendantOf HScale o) => IsHScale o

Type class for types which can be safely cast to HScale, for instance with toHScale.

Instances

(GObject o, IsDescendantOf HScale o) => IsHScale o

Defined in GI.Gtk.Objects.HScale

toHScale :: (MonadIO m, IsHScale o) => o -> m HScale

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

Methods

Overloaded methods

new

hScaleNew

Arguments

:: (HasCallStack, MonadIO m, IsAdjustment a)

=> Maybe a

adjustment: the Adjustment which sets the range of the scale.

-> m HScale

Returns: a new HScale.

Deprecated: (Since version 3.2)Use scaleNew with OrientationHorizontal instead

Creates a new HScale.

newWithRange

hScaleNewWithRange

Arguments

:: (HasCallStack, MonadIO m)

=> Double

min: minimum value

-> Double

max: maximum value

-> Double

step: step increment (tick size) used with keyboard shortcuts

-> m HScale

Returns: a new HScale

Deprecated: (Since version 3.2)Use scaleNewWithRange with OrientationHorizontal instead

Creates a new horizontal scale widget that lets the user input a number between min and max (including min and max) with the increment step. step must be nonzero; it’s the distance the slider moves when using the arrow keys to adjust the scale value.

Note that the way in which the precision is derived works best if step is a power of ten. If the resulting precision is not suitable for your needs, use scaleSetDigits to correct it.
