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.

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
.

:: (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.
