options.
[-height 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. [-state
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. [-width 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.
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.
