The GtkHScale widget is used to allow the user to select a value using
a horizontal slider. To create one, use gtk_hscale_new_with_range().
The position to show the current value, and the number of decimal places shown can be set using the parent GtkScale class's functions.
struct GtkHScale;
The GtkHScale struct contains private data only, and should be accessed using the functions below.
GtkWidget *         gtk_hscale_new                      (GtkAdjustment *adjustment);
Creates a new GtkHScale.
| 
 | the GtkAdjustment which sets the range of the scale. | 
| Returns : | a new GtkHScale. | 
GtkWidget * gtk_hscale_new_with_range (gdouble min,gdouble max,gdouble step);
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 gtk_scale_set_digits() to correct it.
