Name:	\fBclass\fR
Class:	\fBClass\fR
Command-Line Switch:	\fB\-class\fR
.fi
.IP
Specifies a class for the window.
This class will be used when querying the option database for
the window's other options, and it will also be used later for
other purposes such as bindings.
The \fBclass\fR option may not be changed with the \fBconfigure\fR
widget command.

Name:	\fBheight\fR
Class:	\fBHeight\fR
Command-Line Switch:	\fB\-height\fR
.fi
.IP
Specifies the desired height for the window in screen lines.
If this option is equal to zero then the window will
not request any size at all.
.LP
.nf
Name:	\fBwidth\fR
Class:	\fBWidth\fR
Command-Line Switch:	\fB\-width\fR
.fi
.IP
Specifies the desired width for the window in screen columns.
If this option is equal to zero then the window will
not request any size at all.

.SH DESCRIPTION
.PP
The \fBtoplevel\fR command creates a new toplevel widget (given
by the \fIpathName\fR argument).  Additional
options, described above, may be specified on the command line
or in the option database
to configure aspects of the toplevel such as its background color
and relief.  The \fBtoplevel\fR command returns the
path name of the new window.
.PP
A toplevel is similar to a frame except that it is created as a
top-level window: its parent with respect to screen real estate
is the terminal's screen rather than the logical parent from its
path name.  The primary
purpose of a toplevel is to serve as a container for dialog boxes
and other collections of widgets.  The only visible features
of a toplevel are its background color, attributes and border.

.SH "WIDGET COMMAND"
.PP
The \fBtoplevel\fR command creates a new Tcl command whose
name is the same as the path name of the toplevel's window.  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
\fIPathName\fR is the name of the command, which is the same as
the toplevel widget's path name.  \fIOption\fR and the \fIarg\fRs
determine the exact behavior of the command.  The following
commands are possible for toplevel widgets:
.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 \fBtoplevel\fR
command.
.TP
\fIpathName \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. 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 \fBtoplevel\fR
command.

.SH PLACEMENT
The only means to place a toplevel widget on the screen is the
\fBplace\fR geometry manager.

.SH BINDINGS
.PP
When a new toplevel is created, it has no default event bindings:
toplevels are not intended to be interactive.

.SH KEYWORDS
