Graphics.UI.Gtk.Entry.HScale
Description
A horizontal slider widget for selecting a value from a range
- data HScale
- class ScaleClass o => HScaleClass o
- castToHScale :: GObjectClass obj => obj -> HScale
- gTypeHScale :: GType
- toHScale :: HScaleClass o => o -> HScale
- hScaleNew :: Adjustment -> IO HScale
- hScaleNewWithRange :: Double -> Double -> Double -> IO 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.

Arguments
| :: Adjustment |
|
| -> IO HScale |
Creates a new HScale.
Arguments
| :: 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.
