NAME
DXmCreateSvn - Creates an SVN widget
SYNOPSIS
Widget DXmCreateSvn(parent, name, arglist, argcount)
Widget parent;
char *name;
Arg *arglist;
int argcount;
PARAMETERS
The identifier (widget ID) of the parent widget. A character string
that defines the name of the widget. The application argument list.
An integer that represents the number of arguments in the application
argument list. If there are no arguments in the argument list,
argcount must equal 0. However, when argcount equals 0, the argument
list does not have to be Null.
DESCRIPTION
The DXmCreateSvn routine allows you to create a hierarchical structure
of information that is presented to a user in an organized manner and
in a way that lets the user navigate in, and select from, that struc-
ture. Your application need only tell the SVN widget about the organi-
zation of the data and respond to SVN widget callbacks; the SVN widget
is responsible for actually displaying the data.
You can use SVN to display hierarchical information in three different
formats, or modes: Outline format. Tree format, which can be oriented
from the top, the left, in outline form, and in a user-defined style.
Column format, which differs from outline format in that a window pane
separates a set of components from the rest of the display. You can
scroll horizontally on each side, independently of the other side.
However, you have only one vertical scroll bar.
Each SVN line, or entry, in your hierarchy can display as many as
thirty pieces of information (called components) depending on the
amount of information users need. The components can be of three data
types: text, pixmaps, and widgets.
The SVN widget includes additional support routines (also described in
this document) that allow your application to insert and remove compo-
nents, set the text associated with a component, set a component to be
hidden, set and determine a components's width, and determine a compo-
nent's number.
When you create an SVN widget, note that applications must be able to
communicate with the widget through Toolkit routine calls that request
information about and manipulate selections. As such, when you use the
DXmCreateSvn routine to create the SVN widget, you must include the
following SVN callbacks: DXmSvnNattachToSourceCallback DXmSvnNgetEn-
tryCallback DXmSvnNselectAndConfirmCallback

Resources
Callback (or callbacks) made when a widget attaches to the source data
module, which then calls the DXmSvnAddEntries routine to specify the
initial entries (and number of entries) in the data hierarchy. The
callback reason is DXmSvnCRAttachToSource. The default is Null. Ac-
cess is CG. A Boolean resource that, when True, specifies that columns
are to be separated with a line. The default is False. Access is CSG.
The number of pixels between components. The default is 12 pixels.
Access is CSG. Callback made when the widget is detached from the
source data module (the widget is being destroyed). The application
records that this widget will never call back. The callback reason is
DXmSvnCRDetachFromSource. The default is Null. Access is CSG. Call-
back made when the entries currently being displayed to the user have
changed. This change may be in response to an expand or collapse oper-
ation, scrolling, or the application issuing calls to the DXmSvnPosi-
tionDisplay routine.
The callback reason is DXmSvnCRDisplayChanged. An additional
callback field is loc_cursor_entry_number, which is the number
of the entry where the location cursor is currently displayed.
The default is Null. Access is CSG. Specifies which display

get routines.
The callback reason is DXmSvnCRGetEntry. Other callback fields
are as follows:
tab(@); lfHB lfHB l l . _
Field@Description

entry_tag@T{ The value (previously set in the application with
the DXmSvnSetEntry or DXmSvnAddEntries routine) associated with
the entry_number field T}

cation cursor is currently displayed T}

The default is Null. Access is CSG. The height of the pixmap
for a specific type of highlighted image, or "ghost", that fol-
lows the entries as they are dragged. The default is 0. Access

dragging "ghost" (a specific type of highlighted image that fol-
lows the entries as they are dragged) is attached to the cursor.

requests help. The callback reason is DXmSvnCRHelpRequested.

event@T{ A pointer to the X event structure describing the event
that generated this callback T}
_
Note that the values for the entry_number and loc_cursor_en-
try_number fields vary depending on how the user requests help,
as follows: The user presses the Help key on the keyboard.
In this instance, the SVN widget returns a valid entry number in
the loc_cursor_entry_number field and then invokes SVN help for
the corresponding entry. The user invokes context-sensitive
help and then clicks on MB1.
In this instance, the application uses context-sensitive help
(which you include in the application by specifying the
DXmHelpOnContext routine) to invoke help for an SVN subwidget.
A negative value in the entry_number field indicates which of
the following subwidgets the user has clicked on to request
help:
tab(@); lfHB lfHB l l . _
Subwidget@Value
_
DXmSvnKHelpScroll@T{ -1 T}
DXmSvnKHelpNavButton@T{ -2 T}
DXmSvnKNavWindow @T{ -3 T}

entry level should be indented. The default is 16 pixels. Ac-
cess is CSG. A Boolean resource that, when True, allows
scrolling in outline and column display mode, but not in tree

fault is Null. Access is CSG. The number of entries. The
value increases or decreases as entries are changed by the
DXmSvnAddEntries and DXmSvnDeleteEntries routines. Access is G
(read-only). The identifier (widget ID) of the primary horizon-
tal scroll bar. The default is Null. Access is G (read-only).

are as follows:
tab(@); lfHB lfHB l l . _
Field@Description
_
loc_cursor_entry_number@T{ The number of the entry where the lo-
cation cursor is currently displayed T}

that generated this callback T}
_
The default is Null. Access is CSG. The base x position of the
secondary window in the column view. The default is 0. Access
is CSG. A Boolean resource that, when True, specifies that sec-
ondary components still exist even though they are not visible
in the column view. The default is False. Access is CSG. The
identifier (widget ID) of the secondary widget in the SVN dis-
play. The default is Null. Access is G (read-only). Callback
made when the user double clicks MB1 on a single entry, indicat-
ing that the user wants to expand or collapse (contract) the en-
try. The application can determine which entry has been se-
lected by either examining the entry_number and component_number
fields of the callback data structure or by calling the
DXmSvnGetSelections routine.
This callback is also called when all three of the following
conditions exist: The DXmSvnNMultipleSelections resource is set
to True. There is no DXmSvnNExtendConfirm callback supplied.
The user has double clicked to terminate the selection of a
range of entries.
In such an instance, the individual calls are from the highest
entry number selected through the lowest entry number selected.
The callback reason is DXmSvnCRSelectAndConfirm. Other callback
fields are as follows:
tab(@); lfHB lfHB l l . _

positioned T}

cation cursor is currently displayed T}

DXmSvnKselectEntryOrComp@T{ Selects either the entire entry (if
the selection is made on the primary side) or only the component
(if the selection is made on the secondary side of the display
window). T}
_
The default is DXmSvnKselectEntry. Access is CSG. The user has
used MB2 to drag selected entries to another location. Note
that the use of this resource is valid only when application-
controlled dragging has not been set (with the DXmSvnNdragging-
Callback and DXmSvnNdraggingEndCallback callbacks).
