       See the options manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS

       Command-Line Name:-height
       Database Name:  height
       Database Class: 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 Tk_GetPixels); for text  it
              is in lines of text.  If this option is not specified, the label's desired height is computed from
              the size of the image or bitmap or text being displayed in it.

       Command-Line Name:-state
       Database Name:  state
       Database Class: State

              Specifies one of three states for the label:  normal, active, or disabled.  In  normal  state  the
              button  is  displayed using the -foreground and -background options.  In active state the label is
              displayed using the -activeforeground and -activebackground options.  In the  disabled  state  the
              -disabledforeground and -background options determine how the button is displayed.

       Command-Line Name:-width
       Database Name:  width
       Database Class: 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 Tk_GetPixels); for text  it
              is in characters.  If this option is not specified, the label's desired width is computed from the
              size of the image or bitmap or text being displayed in it.

DESCRIPTION

       The label command creates a new window (given by the pathName 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  label  command
       returns  its pathName argument.  At the time this command is invoked, there must not exist a window named
       pathName, but pathName's parent must exist.

       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 -wraplength option) and one of the characters may optionally be underlined
       using  the  -underline  option.   The label can be manipulated in a few simple ways, such as changing its
       relief or text, using the commands described below.

WIDGET COMMAND

       The label command creates a new Tcl command whose name is pathName.  This command may be used  to  invoke
       various operations on the widget.  It has the following general form:
              pathName option ?arg arg ...?
       Option and the args determine the exact behavior of the command.  The following commands are possible for
       label widgets:

       pathName cget option
              Returns the current value of the configuration option given by option.  Option may have any of the
              values accepted by the label command.

       pathName configure ?option? ?value option value ...?
              Query  or  modify  the  configuration options of the widget.  If no option is specified, returns a
              list describing all of the available options for pathName (see Tk_ConfigureInfo for information on
              the  format  of this list).  If option is specified with no value, 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 option is specified).  If one or more option-value 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.  Option may have any of the values accepted by the label command.

BINDINGS

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

EXAMPLE

              # Make the widgets
              label .t -text "This widget is at the top"    -bg red
              label .b -text "This widget is at the bottom" -bg green
              label .l -text "Left\nHand\nSide"
              label .r -text "Right\nHand\nSide"
              text .mid
              .mid insert end "This layout is like Java's BorderLayout"
              # Lay them out
              pack .t   -side top    -fill x
              pack .b   -side bottom -fill x
              pack .l   -side left   -fill y
              pack .r   -side right  -fill y
              pack .mid -expand 1    -fill both
