GtkScrollbar

GtkScrollbar — Base class for GtkHScrollbar and GtkVScrollbar

Synopsis

#include <gtk/gtk.h>

                    GtkScrollbar;
GtkWidget *         gtk_scrollbar_new                   (GtkOrientation orientation,
                                                         GtkAdjustment *adjustment);

Description

The GtkScrollbar widget is the base class for GtkHScrollbar and GtkVScrollbar. It can be used in the same way as these, by setting the "orientation" property appropriately.

The position of the thumb in a scrollbar is controlled by the scroll adjustments. See GtkAdjustment for the fields in an adjustment - for GtkScrollbar, the GtkAdjustment.value field represents the position of the scrollbar, which must be between the GtkAdjustment.lower field and GtkAdjustment.upper - GtkAdjustment.page_size. The GtkAdjustment.page_size field represents the size of the visible scrollable area. The GtkAdjustment.step_increment and GtkAdjustment.page_increment fields are used when the user asks to step down (using the small stepper arrows) or page down (using for example the PageDown key).
