Description
A horizontal slider widget for selecting a value from a range
Synopsis
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.

hScaleNew
:: Adjustmentadjustment - the Adjustment which sets the range of the scale.
-> IO HScale
Creates a new HScale.
hScaleNewWithRange
:: Doublemin - minimum value
-> Doublemax - maximum value
-> Doublestep - step increment (tick size) used with keyboard shortcuts
-> 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 Graphics.UI.Gtk.Abstract.Scale.scaleSetDigits to correct it.
