- 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 isn't 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 isn't specified, the label's desired
width is computed from the size of the image or bitmap or text
being displayed in it.
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.
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.
When a new label is created, it has no default event bindings:
labels are not intended to be interactive.
