 .SH "WIDGET-SPECIFIC OPTIONS"
 .OP \-height height Height
 Specifies a desired height for the label.
 If an image or bitmap is being displayed in the label then the value is in
 screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR);
 for text it is in lines of text.
 If this option isn't specified, the label's desired height is computed
 from the size of the image or bitmap or text being displayed in it.
 .OP \-state state State
 Specifies one of three states for the label:  \fBnormal\fR, \fBactive\fR,
 or \fBdisabled\fR.  In normal state the button is displayed using the
 \fBforeground\fR and \fBbackground\fR options.  In active state
 the label is displayed using the \fBactiveForeground\fR and
 \fBactiveBackground\fR options.  In the disabled state the
 \fBdisabledForeground\fR and \fBbackground\fR options determine how
 the button is displayed.
 .OP \-width width Width
 Specifies a desired width for the label.
 If an image or bitmap is being displayed in the label then the value is in
 screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR);
 for text it is in characters.
 If this option isn't specified, the label's desired width is computed

 .SH DESCRIPTION
 .PP
 The \fBlabel\fR command creates a new window (given by the
 \fIpathName\fR argument) and makes it into a label widget.
 Additional
 options, described above, may be specified on the command line
 or in the option database
 to configure aspects of the label such as its colors, font,
 text, and initial relief.  The \fBlabel\fR command returns its
 \fIpathName\fR argument.  At the time this command is invoked,
 there must not exist a window named \fIpathName\fR, but
 \fIpathName\fR's parent must exist.
 .PP
 A label is a widget that displays a textual string, bitmap or image.
 If text is displayed, it must all be in a single font, but it
 can occupy multiple lines on the screen (if it contains newlines
 or if wrapping occurs because of the \fBwrapLength\fR option) and
 one of the characters may optionally be underlined using the
 \fBunderline\fR option.
 The label can be manipulated in a few simple ways, such as
 changing its relief or text, using the commands described below.

 .SH "WIDGET COMMAND"
 .PP
 The \fBlabel\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:
 .CS
 \fIpathName option \fR?\fIarg arg ...\fR?
 .CE
 \fIOption\fR and the \fIarg\fRs
 determine the exact behavior of the command.  The following
 commands are possible for label 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 \fBlabel\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 (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 \fBlabel\fR
 command.

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