- .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
- .VS
- that displays a textual string or bitmap.
- .VE
- 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:
- .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 label widgets:
- .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.
-
- .SH KEYWORDS
- label, widget
