GI.Gtk.Objects.HScale
Description
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.
Synopsis
- newtype HScale = HScale (ManagedPtr HScale)
- class (GObject o, IsDescendantOf HScale o) => IsHScale o
- toHScale :: (MonadIO m, IsHScale o) => o -> m HScale
- noHScale :: Maybe HScale
- hScaleNew :: (HasCallStack, MonadIO m, IsAdjustment a) => Maybe a -> m HScale
- hScaleNewWithRange :: (HasCallStack, MonadIO m) => Double -> Double -> Double -> m HScale

new
Arguments
| :: (HasCallStack, MonadIO m, IsAdjustment a) | |
| => Maybe a |
|
| -> m HScale | Returns: a new |
Deprecated: (Since version 3.2)Use scaleNew with OrientationHorizontal instead
Creates a new HScale.
newWithRange
Arguments
| :: (HasCallStack, MonadIO m) | |
| => Double |
|
| -> Double |
|
| -> Double |
|
| -> m HScale | Returns: a new |
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.
