#### Arguments for Label ¶

`:height`

  Name=`"height" Class=`"`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.

`:width`

  Name=`"width" Class=`"`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.

#### A Label Widget’s Arguments ¶

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.
