WIDGET-SPECIFIC OPTIONS
Name: height
Class: Height
Switch: -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 isn't specified, the label's
desired height is computed from the size of the image or bitmap or
text being displayed in it.
Name: state
Class: State
Switch: -state
Specifies one of three states for the label: normal, active, or
disabled. In normal state the label 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.
Name: width
Class: Width
Switch: -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 isn't 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 method creates a new window (given by the $widget 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 $widget argument. At
the time this command is invoked, there must not exist a window named
$widget, but $widget'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 METHODS
The Label method creates a widget object. This object supports the
configure and cget methods described in Tk::options which can be used
to enquire and modify the options described above. The widget also
inherits all the methods provided by the generic Tk::Widget class.
BINDINGS
When a new label is created, it has no default event bindings: labels
are not intended to be interactive.
