\fBXmScrollBar\fP \(em The ScrollBar widget class
.iX "XmScrollBar"
.iX "widget class" "ScrollBar"
.SH "SYNOPSIS"
.PP
.nf
#include <Xm/ScrollBar\&.h>
.fi
.SH "DESCRIPTION"
.PP
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\&.
.PP
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\&.
.PP
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\&.
.PP
If the ScrollBar parent is an automatic ScrolledWindow, the
\fBXmNtraversalOn\fP default is True\&. Otherwise, the default is False\&.
.PP
ScrollBar holds the \fBXmQTnavigator\fP traits\&.
.SS "Classes"
.PP
ScrollBar inherits behavior, resources, and traits from the \fBCore\fP and
\fBXmPrimitive\fP classes\&.
.PP
The class pointer is \fBxmScrollBarWidgetClass\fP\&.
.PP
The class name is \fBXmScrollBar\fP\&.
.SS "New Resources"
.PP
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 \fB\&.Xdefaults\fP file, remove the \fBXmN\fP or
\fBXmC\fP prefix and use the remaining letters\&. To specify one of the defined
values for a resource in a \fB\&.Xdefaults\fP file, remove the \fBXm\fP 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 \fBXtSetValues\fP (S),
retrieved by using \fBXtGetValues\fP (G), or is not applicable (N/A)\&.

pointer moves beyond 1 ScrollBar width of the ScrollBar edge\&.
Whenever the slider snaps back, the ScrollBar \fBdragCallback\fP is
called if there is one\&.

With an argument of \fBLeft\fP, or 1 for compatibility, it moves the
slider left by one page increment\&.
If \fBXmNprocessingDirection\fP is \fBXmMAX_ON_RIGHT\fP or
\fBXmMAX_ON_BOTTOM\fP,
movement to the left or top calls the callbacks for
\fBXmNpageDecrementCallback\fP\&.
If \fBXmNprocessingDirection\fP is \fBXmMAX_ON_LEFT\fP or
\fBXmMAX_ON_TOP\fP,
movement to the left or top calls the
\fBXmNpageIncrementCallback\fP
callbacks\&. The \fBXmNvalueChangedCallback\fP is called if the
\fBXmNpageIncrementCallback\fP or \fBXmNpageDecrementCallback\fP is NULL\&.
.IP "PrimitiveHelp():" 10
Calls the callbacks for \fBXmNhelpCallback\fP if any exist\&. If there are no help
callbacks for this widget, this action calls the help callbacks
for the nearest ancestor that has them\&.
.IP "PrimitiveNextTabGroup():" 10
Traverses to the first item in the next tab group\&. If
the current tab group is the last entry in the tab group list, it
wraps to the beginning of the tab group list\&.
.IP "PrimitiveParentActivate():" 10
If the parent is a manager,
passes the event to the parent\&.
.IP "PrimitivePrevTabGroup():" 10
Traverses to the first item in the previous tab group\&.
If the beginning of the tab group list is reached, it wraps to the end
of the tab group list\&.
.IP "Release():" 10
If the button press occurs within the slider and the slider position
is changed, the callbacks for \fBXmNvalueChangedCallback\fP are called\&.
.IP "Select():" 10
\fBIn arrow\fP:
Moves the slider by one increment in the direction
of the arrow\&.
If \fBXmNprocessingDirection\fP is \fBXmMAX_ON_RIGHT\fP or
\fBXmMAX_ON_BOTTOM\fP, movement toward the right or
bottom calls the callbacks for \fBXmNincrementCallback\fP,
and movement to the left or top calls the callbacks for
\fBXmNdecrementCallback\fP\&.
If \fBXmNprocessingDirection\fP is \fBXmMAX_ON_LEFT\fP or
\fBXmMAX_ON_TOP\fP, movement toward the right or
bottom calls the callbacks for \fBXmNdecrementCallback\fP,
and movement to the left or top calls the callbacks for
\fBXmNincrementCallback\fP\&.
The \fBXmNvalueChangedCallback\fP is called if the
\fBXmNincrementCallback\fP or \fBXmNdecrementCallback\fP is NULL\&.
.IP "" 10
\fBIn scroll region between an arrow and the slider\fP:
Moves the slider by one page increment in the direction of the arrow\&.
If \fBXmNprocessingDirection\fP is \fBXmMAX_ON_RIGHT\fP or
\fBXmMAX_ON_BOTTOM\fP, movement toward the right or
bottom calls the callbacks for \fBXmNpageIncrementCallback\fP,
and movement to the left or top calls the callbacks for
\fBXmNpageDecrementCallback\fP\&.
If \fBXmNprocessingDirection\fP is \fBXmMAX_ON_LEFT\fP or
\fBXmMAX_ON_TOP\fP, movement toward the right or
bottom calls the callbacks for \fBXmNpageDecrementCallback\fP,
and movement to the left or top calls the callbacks for
\fBXmNpageIncrementCallback\fP\&.
The \fBXmNvalueChangedCallback\fP is called if the
\fBXmNpageIncrementCallback\fP or \fBXmNpageDecrementCallback\fP is
NULL\&.
.IP "" 10
\fBIn slider\fP:
Activates the interactive dragging of the slider\&.
.IP "" 10
If the button is held down in either the arrows or the scroll region
longer than the \fBXmNinitialDelay\fP resource, the slider is
moved again by the same increment and the same callbacks are called\&.
After the initial delay has been used, the time delay changes to the
time defined by the resource \fBXmNrepeatDelay\fP\&.
.IP "TopOrBottom():" 10
\fB<Ctrl>\fP\fB<Btn1Down>\fP in an arrow or in the scroll region between
an arrow and the slider moves the slider as far as possible in the
direction of the arrow\&. If \fBXmNprocessingDirection\fP is
\fBXmMAX_ON_RIGHT\fP or \fBXmMAX_ON_BOTTOM\fP, movement toward the
right or bottom calls the callbacks for \fBXmNtoBottomCallback\fP, and
movement to the left or top calls the callbacks for
\fBXmNtoTopCallback\fP\&. If \fBXmNprocessingDirection\fP is
\fBXmMAX_ON_LEFT\fP or \fBXmMAX_ON_TOP\fP, movement toward the right
or bottom calls the callbacks for \fBXmNtoTopCallback\fP, and movement
to the left or top calls the callbacks for \fBXmNtoBottomCallback\fP\&.
The \fBXmNvalueChangedCallback\fP is called if the
\fBXmNtoTopCallback\fP or \fBXmNtoBottomCallback\fP is NULL\&.
Pressing
\fB<Key>\fP\fB<osfBeginLine>\fP or \fB<Key>\fP\fB<osfBeginData>\fP moves the slider to
the minimum value and invokes the \fBXmNtoTopCallback\fP\&. Pressing
\fB<Key>\fP\fB<osfEndLine>\fP or \fB<Key>\fP\fB<osfEndData>\fP moves the slider to the
maximum value and invokes the \fBXmNtoBottomCallback\fP\&.
