Implemented Interfaces

GtkHScale implements AtkImplementorIface, GtkBuildable and GtkOrientable.

Description

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.

Details

struct GtkHScale

struct GtkHScale;

The GtkHScale struct contains private data only, and should be accessed using the functions below.


gtk_hscale_new ()

GtkWidget *         gtk_hscale_new                      (GtkAdjustment *adjustment);

Creates a new GtkHScale.

adjustment :

the GtkAdjustment which sets the range of the scale.

Returns :

a new GtkHScale.

gtk_hscale_new_with_range ()

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.

min :

minimum value

max :

maximum value

step :

step increment (tick size) used with keyboard shortcuts

Returns :

a new GtkHScale
