DESCRIPTION

The Label widget extends the default Tk label. Options have been added to provide visual effect depending on the state of the Label, DynamicHelp options, and Drag and Drop.

WIDGET-SPECIFIC OPTIONS

-draginitcmd
  Specifies a command to be called when dragevent occurs on widget. draginitcmd must be a command conforming to the description of the option draginitcmd of DragSite::register.
  If draginitcmd is empty, the internal draginitcmd command is used instead and returns:

    IMAGE {copy} <image name> | if an image is displayed.
    BITMAP {copy} <bitmap name> | if a bitmap is displayed.
    TEXT {copy} <text> | if a text is displayed.

  Note that if dragtype option is not empty, its value is used instead of those above.

-dragtype
  Specifies an alternate type of dragged object.

  Specifies a command to be called when drop occurs on the widget. dropcmd must be a command conforming to the description of the option dropcmd of DropSite::register.
  If dropcmd is empty, the command updates the label following the type of the data:

    COLOR or FGCOLOR | reconfigure the foreground of the Label.
    BGCOLOR | reconfigure the background of the Label.
    IMAGE | reconfigure the Label to display the associated image.
    BITMAP | reconfigure the Label to display the associated bitmap. image option is set to empty.
    TEXT, or any other tag | reconfigure the Label to display the associated string. image and bitmap options are set to empty.

-dropenabled
  A boolean specifying if drop is enabled.

-dropovercmd
  Specifies a command to be called when drag icon is over the widget. dropovercmd must be a command conforming to the description of the option dropovercmd of DropSite::register.
  If dropovercmd is empty, Label always accepts the drop if data type is FGCOLOR, COLOR, BGCOLOR, and accepts all other data type only if state is normal.

-droptypes
  Specifies a list of accepted dropped object/operation. See option droptypes of DropSite::register. for more infromation. Default accepts FGCOLOR, COLOR, BGCOLOR, TEXT, BITMAP and IMAGE, all with copy and move operations.

-focus
  Specifies a pathname to set the focus on for Label::setfocus command.

-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, 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 image or bitmap or text being displayed in it.

-helptext
  Text for dynamic help. If empty, no help is available for this widget. See also DynamicHelp.

-helptype
  Type of dynamic help. Use balloon or variable. See also DynamicHelp.

-helpvar
  Variable to use when helptype option is variable. See also DynamicHelp.

-name
  Specifies a standard name for the label. If the option *nameName is found in the resource database, then text and underline options are extracted from its value.

-state
  Specifies one of two states for the Label: normal or disabled. In normal state the text of the Label is displayed using the foreground option. In disabled state the text of the Label is displayed using the disabledforeground option.

-underline
  Specifies the integer index of a character to underline in the label. 0 corresponds to the first character of the text displayed, 1 to the next character, and so on.
  The binding <Alt-char> is automatically set on the toplevel of the Label to call Label::setfocus.

-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, for text it is in characters. If this option isn't specified, the label's desired width is computed from the size of the image or bitmap or text being displayed in it.
