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.
- newtype HScale = HScale (ManagedPtr HScale)

Methods
new
:: (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
:: (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.
