This kind of widget is commonly used for volume controls in multimedia applications, and GTK+ provides a GtkVolumeButton subclass that is tailored for this use case.

Creates a GtkScaleButton, with a range between
Since 2.12 gtk_scale_button_set_adjustment ()void gtk_scale_button_set_adjustment (GtkScaleButton *button, GtkAdjustment *adjustment);
Sets the GtkAdjustment to be used as a model
for the GtkScaleButton's scale.
See
Since 2.12 gtk_scale_button_set_icons ()void gtk_scale_button_set_icons (GtkScaleButton *button, const gchar **icons); Sets the icons to be used by the scale button. For details, see the "icons" property.
Since 2.12 gtk_scale_button_set_value ()void gtk_scale_button_set_value (GtkScaleButton *button, gdouble value); Sets the current value of the scale; if the value is outside the minimum or maximum range values, it will be clamped to fit inside them. The scale button emits the "value-changed" signal if the value changes.
Since 2.12 gtk_scale_button_get_adjustment ()GtkAdjustment* gtk_scale_button_get_adjustment (GtkScaleButton *button);
Gets the GtkAdjustment associated with the GtkScaleButton's scale.
See
Since 2.12 gtk_scale_button_get_value ()gdouble gtk_scale_button_get_value (GtkScaleButton *button); Gets the current value of the scale button.
Since 2.12 gtk_scale_button_get_popup ()GtkWidget* gtk_scale_button_get_popup (GtkScaleButton *button); Retrieves the popup of the GtkScaleButton.
Since 2.14 gtk_scale_button_get_plus_button ()GtkWidget* gtk_scale_button_get_plus_button (GtkScaleButton *button); Retrieves the plus button of the GtkScaleButton.
Since 2.14 gtk_scale_button_get_minus_button ()GtkWidget* gtk_scale_button_get_minus_button (GtkScaleButton *button); Retrieves the minus button of the GtkScaleButton.
Since 2.14 gtk_scale_button_set_orientation ()void gtk_scale_button_set_orientation (GtkScaleButton *button, GtkOrientation orientation); Sets the orientation of the GtkScaleButton's popup window.
