NAME

       XmScrollBar — The ScrollBar widget class "XmScrollBar" "widget class" "ScrollBar"

SYNOPSIS

       #include <Xm/ScrollBar.h>

DESCRIPTION

       The  ScrollBar  widget  allows  the  user  to  view  data  that is too large to be displayed all at once.
       ScrollBars are usually located inside a ScrolledWindow and adjacent to the widget that contains the  data
       to be viewed. When the user interacts with the ScrollBar, the data within the other widget scrolls.

       A  ScrollBar consists of two arrows placed at each end of a rectangle. The rectangle is called the scroll
       region. A smaller rectangle, called the slider, is placed within the scroll region. The data is  scrolled
       by  clicking  either  arrow,  selecting  on  the scroll region, or dragging the slider.  When an arrow is
       selected, the slider within the scroll region is moved in  the  direction  of  the  arrow  by  an  amount
       supplied by the application. If the mouse button is held down, the slider continues to move at a constant
       rate.

       The  ratio of the slider size to the scroll region size typically corresponds to the relationship between
       the size of the visible data and the total size of the data. For example, if 10 percent of  the  data  is
       visible,  the  slider  typically  occupies 10 percent of the scroll region. This provides the user with a
       visual clue to the size of the invisible data.

       If the ScrollBar parent is an automatic ScrolledWindow, the XmNtraversalOn default  is  True.  Otherwise,
       the default is False.

       ScrollBar holds the XmQTnavigator traits.

   Classes
       ScrollBar inherits behavior, resources, and traits from the Core and XmPrimitive classes.

       The class pointer is xmScrollBarWidgetClass.

       The class name is XmScrollBar.

   New Resources
       The  following  table  defines  a  set  of  widget  resources used by the programmer to specify data. The
       programmer can also set the resource values for the inherited classes to set attributes for this  widget.
       To  reference  a  resource by name or by class in a .Xdefaults file, remove the XmN or XmC prefix and use
       the remaining letters. To specify one of the defined values for a resource in a .Xdefaults  file,  remove
       the  Xm  prefix  and  use  the  remaining  letters  (in  either  lowercase  or uppercase, but include any
       underscores between words).  The codes in the access column indicate if the given resource can be set  at
       creation time (C), set by using XtSetValues (S), retrieved by using XtGetValues (G), or is not applicable
       (N/A).
