NAME
DXmCreateSvn - Creates an SVN widget
SYNOPSIS
Widget DXmCreateSvn(
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 structure. Your application need only tell the SVN widget about the
organization 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 ori-
ented 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 com-
ponents, set the text associated with a component, set a component to be hidden, set and determine a component's width, and determine a
component'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 DXmSvnNgetEntryCallback 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. Access
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. Callback made when the entries currently being displayed to the user have
changed. This change may be in response to an expand or collapse operation, scrolling, or the application issuing calls to the DXmSvnPosi-

Access is CSG. Callback made when the user requests help. The callback reason is DXmSvnCRHelpRequested. Other callback fields are
as follows:
---------------------------------------------------------------------
Field Description
---------------------------------------------------------------------

which help was requested
time The time when the user requested help

requested
entry_tag The value (previously set in the applica-
tion with the DXmSvnSetEntry routine)
associated with the entry_number field
entry_level The level number of the entry
loc_cursor_entry_number The number of the entry where the location
cursor is currently displayed
event A pointer to the X event structure
describing the event that generated this
callback
---------------------------------------------------------------------
Note that the values for the entry_number and loc_cursor_entry_number fields vary depending on how the user requests help, as fol-
lows: 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 DXmHelpOnCon-
text routine) to invoke help for an SVN subwidget. A negative value in the entry_number field indicates which of the following sub-
widgets the user has clicked on to request help:
-----------------------------
Subwidget Value
-----------------------------
DXmSvnKHelpScroll -1
DXmSvnKHelpNavButton -2
DXmSvnKNavWindow -3
-----------------------------
The default is Null. Access is CSG. The number of pixels each entry level should be indented. The default is 16 pixels. Access
is CSG. A Boolean resource that, when True, allows scrolling in outline and column display mode, but not in tree mode. If an
application uses the existing index window instead, this resource must be set to False. The default is True. Access is CSG. The
percentage of the display window that is in the primary side of the column view. The default is 50 percent. Access is CSG. The
identifier (widget ID) of the primary window widget in the SVN display. The default is Null. Access is G (read-only). A Boolean
resource that, when True, allows the user to specify multiple selections. The default is True. Access is CSG. The title for a
pop-up navigation window. The default 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 horizontal scroll bar. The default is Null. Access is G (read-only). The identifier (widget ID) of the pane widget. The

played

describing the event that generated
this callback
----------------------------------------------------------------
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 secondary 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 display. The
default is Null. Access is G (read-only). Callback made when the user double clicks MB1 on a single entry, indicating that the
user wants to expand or collapse (contract) the entry. The application can determine which entry has been selected by either exam-
ining 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.

application with the DXmSvnSetEntry
or DXmSvnAddEntries routine) associ-
ated with the entry_number field
entry_level The level number of the entry
loc_cursor_entry_number The number of the entry where the
location cursor is currently dis-
played

selection is made on the sec-
ondary side of the display
window).
------------------------------------------------------------
The default is DXmSvnKselectEntry. Access is CSG. The user has used MB2 to drag selected entries to another location. Note that
