'\" 
'\" The definitions below are for supplemental macros used in Tcl/Tk
'\" manual entries.
'\"
'\" .HS name section [date [version]]
'\"	Replacement for .TH in other man pages.  See below for valid
'\"	section names.
'\"
'\" .AP type name in/out [indent]
'\"	Start paragraph describing an argument to a library procedure.
'\"	type is type of argument (int, etc.), in/out is either "in", "out",
'\"	or "in/out" to describe whether procedure reads or modifies arg,
'\"	and indent is equivalent to second arg of .IP (shouldn't ever be
'\"	needed;  use .AS below instead)
'\"
'\" .AS [type [name]]
'\"	Give maximum sizes of arguments for setting tab stops.  Type and
'\"	name are examples of largest possible arguments that will be passed
'\"	to .AP later.  If args are omitted, default tab stops are used.
'\"
'\" .BS
'\"	Start box enclosure.  From here until next .BE, everything will be
'\"	enclosed in one large box.
'\"
'\" .BE
'\"	End of box enclosure.
'\"
'\" .VS
'\"	Begin vertical sidebar, for use in marking newly-changed parts
'\"	of man pages.
'\"
'\" .VE
'\"	End of vertical sidebar.
'\"
'\" .DS
'\"	Begin an indented unfilled display.
'\"
'\" .DE
'\"	End of indented unfilled display.

.SH DESCRIPTION
.PP
The \fBiwidgets::disjointlistbox\fR command creates a disjoint pair of listboxs
similar to the OSF/Motif "Book" printing dialog of the "FrameMaker"
program.  It is implementation constists of a two Scrolledlistboxs,
2 buttons, and 2 labels.

The disjoint behavior of this widget exists between the interaction of
the two Scrolledlistboxes with one another.  That is, a given instance
of a Disjointlistbox will never exist, without the aid of a hack magician,
which has Scrolledlistbox widgets with items in common.  That means the
relationship between the two is maintained similar to that of disjoint sets.

Users may transfer items between the two Listbox widgets using the
the two buttons.

Options exists which include the ability to configure the "items" displayed by
the 2 Scrolledlistboxes and to control the placement of the insertion and
removal buttons.
.SH "METHODS"
.PP
The \fBiwidgets::disjointlistbox\fR command creates a new Tcl command whose
name is \fIpathName\fR.  This command may be used to invoke various
operations on the widget.  It has the following general form:
.DS C
\fIpathName option \fR?\fIarg arg ...\fR?
.DE
\fIOption\fR and the \fIarg\fRs
determine the exact behavior of the command.  The following
commands are possible for disjointlistbox widgets:

.SH "WIDGET-SPECIFIC METHODS"
.TP
\fIpathName \fBcget\fR \fIoption\fR
Returns the current value of the configuration option given
by \fIoption\fR.
\fIOption\fR may have any of the values accepted by the \fBiwidgets::disjointlistbox\fR
command.
.TP
\fIpathName\fR \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR?
Query or modify the configuration options of the widget.
If no \fIoption\fR is specified, returns a list describing all of
the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for
information on the format of this list).  If \fIoption\fR is specified
with no \fIvalue\fR, then the command returns a list describing the
one named option (this list will be identical to the corresponding
sublist of the value returned if no \fIoption\fR is specified).  If
one or more \fIoption\-value\fR pairs are specified, then the command
modifies the given widget option(s) to have the given value(s);  in
this case the command returns an empty string.
\fIOption\fR may have any of the values accepted by the \fBiwidgets::disjointlistbox\fR
command.
.TP
\fIpathName \fBsetlhs\fR
Set the current contents of the left-most Scrolledlistbox with the input list
of items.  Removes all (if any) items from the right-most Scrolledlistbox
which exist in the input list option to maintain the disjoint property
between the two
.TP
\fIpathName \fBsetrhs\fR
Set the current contents of the right-most Scrolledlistbox with the input list
of items.  Removes all (if any) items from the left-most Scrolledlistbox
which exist in the input list option to maintain the disjoint property
between the two
.TP
\fIpathName \fBgetlhs\fR
Returns the current contents of the left-most Scrolledlistbox
.TP
\fIpathName \fBgetrhs\fR
Returns the current contents of the right-most Scrolledlistbox
.TP
\fIpathName \fBinsertlhs\fR
Add the input list of items to the current contents of the left-most
Scrolledlistbox.  Removes all (if any) items from the right-most Scrolledlistbox
which exist in the input list option to maintain the disjoint property
between the two
.TP
\fIpathName \fBinsertrhs\fR
Add the input list of items to the current contents of the right-most
Scrolledlistbox.  Removes all (if any) items from the left-most Scrolledlistbox
which exist in the input list option to maintain the disjoint property
between the two.
