WIDGET-SPECIFIC OPTIONS
Name: height
Class: Height
Command-Line Switch: -height
Specifies a desired height for the label.
If a 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 bitmap or text being displayed in it.
Name: width
Class: Width
Command-Line Switch: -width
Specifies a desired width for the label.
If a 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 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 or bitmap.
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 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.
