26 [-height height] Specifies a desired height for the label. If an image
27 or bitmap is being displayed in the label then the value is in screen
28 units (i.e. any of the forms acceptable to Tk_GetPixels); for text it
29 is in lines of text. If this option is not specified, the label's
30 desired height is computed from the size of the image or bitmap or text
31 being displayed in it. [-state state] Specifies one of three states
32 for the label: normal, active, or disabled. In normal state the but‐
33 ton is displayed using the foreground and background options. In
34 active state the label is displayed using the activeForeground and
35 activeBackground options. In the disabled state the disabledForeground
36 and background options determine how the button is displayed.
37 [-width width] Specifies a desired width for the label. If an image or
38 bitmap is being displayed in the label then the value is in screen
39 units (i.e. any of the forms acceptable to Tk_GetPixels); for text it
40 is in characters. If this option is not specified, the label's desired
41 width is computed from the size of the image or bitmap or text being
42 displayed in it.

46 The label command creates a new window (given by the pathName argument)
47 and makes it into a label widget. Additional options, described above,
48 may be specified on the command line or in the option database to con‐
49 figure aspects of the label such as its colors, font, text, and initial
50 relief. The label command returns its pathName argument. At the time
51 this command is invoked, there must not exist a window named pathName,
52 but pathName's parent must exist.
53 A label is a widget that displays a textual string, bitmap or image.
55 If text is displayed, it must all be in a single font, but it can
56 occupy multiple lines on the screen (if it contains newlines or if
57 wrapping occurs because of the wrapLength option) and one of the char‐
58 acters may optionally be underlined using the underline option. The
59 label can be manipulated in a few simple ways, such as changing its
60 relief or text, using the commands described below.
61
63 The label command creates a new Tcl command whose name is pathName.
64 This command may be used to invoke various operations on the widget.
65 It has the following general form:
66 pathName option ?arg arg ...?
67 Option and the args determine the exact behavior of the command. The
68 following commands are possible for label widgets:
69 pathName cget option
71 Returns the current value of the configuration option given by
72 option. Option may have any of the values accepted by the label
73 command.
74 pathName configure ?option? ?value option value ...?
76 Query or modify the configuration options of the widget. If no
77 option is specified, returns a list describing all of the avail‐
78 able options for pathName (see Tk_ConfigureInfo for information
79 on the format of this list). If option is specified with no
80 value, then the command returns a list describing the one named
81 option (this list will be identical to the corresponding sublist
82 of the value returned if no option is specified). If one or
83 more option-value pairs are specified, then the command modifies
84 the given widget option(s) to have the given value(s); in this
85 case the command returns an empty string. Option may have any
86 of the values accepted by the label command.
87
89 When a new label is created, it has no default event bindings: labels
90 are not intended to be interactive.
