Description

A horizontal slider widget for selecting a value from a range

Synopsis

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

hScaleNew Source

Arguments

:: Adjustment

adjustment - the Adjustment which sets the range of the scale.

-> IO HScale 

Creates a new HScale.

hScaleNewWithRange Source

Arguments

:: Double

min - minimum value

-> Double

max - maximum value

-> Double

step - 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 scaleSetDigits to correct it.
