A horizontal slider widget for selecting a value from a range

- class ScaleClass o => HScaleClass o
- castToHScale :: GObjectClass obj => obj -> HScale
- gTypeHScale :: GType
- toHScale :: HScaleClass o => o -> HScale

Detail
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.

Constructors
:: Adjustment |
|
-> IO HScale |
Creates a new HScale
.
:: Double |
|
-> Double |
|
-> Double |
|
-> IO HScale |
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.
