See Tk::options for details of the standard 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.
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.
