Description

The GtkScale widget is an abstract class, used only for deriving the subclasses GtkHScale and GtkVScale.

Details

struct GtkScale

struct GtkScale;

The GtkScale struct contains the following fields. (These fields should be considered read-only. They should never be set by an application.)

guint draw_value;non-zero if the scale's current value is displayed next to the slider.
guint value_pos;the position in which the textual value is displayed, selected from GtkPositionType.

gtk_scale_set_digits ()

void        gtk_scale_set_digits            (GtkScale *scale,
                                             gint digits);

Sets the number of decimal places that are displayed in the value.

scale :a GtkScale.
digits :the number of decimal places to display, e.g. use 1 to display 1.0, 2 to display 1.00 etc.

gtk_scale_set_draw_value ()

void        gtk_scale_set_draw_value        (GtkScale *scale,
                                             gboolean draw_value);

Specifies whether the current value is displayed as a string next to the slider.

scale :a GtkScale.
draw_value : 

gtk_scale_set_value_pos ()

void        gtk_scale_set_value_pos         (GtkScale *scale,
                                             GtkPositionType pos);

Sets the position in which the current value is displayed.

scale :a GtkScale.
pos :the position in which the current value is displayed.

gtk_scale_get_value_width ()

gint        gtk_scale_get_value_width       (GtkScale *scale);

An internal function used to get the maximum width needed to display the value string.

scale :a GtkScale.
Returns :the maximum width needed to display the value string.

Args

"digits" (gint : Read / Write)

The number of decimal places that are displayed in the value.

"draw_value" (gboolean : Read / Write)

If the current value is displayed as a string next to the slider.

"value_pos" (GtkPositionType : Read / Write)

The position in which the current value is displayed.
