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 is not 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 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.
