DESCRIPTION

28       The  canvasLabel class brings some Tk label widget functionality to the
29       canvas text item, such as a background and a border.
30
31       The canvasLabel is built with a bullet rectangle on the  left  side  of
32       the text. The relief changes according to the select state, with a tra‐
33       ditionally sunken relief when selected.
34
35       The label has a specific tag, which can be used to retrieve the coordi‐
36       nates of the object or move it, thanks to the canvas facilities.
37
38       stooop::new canvasLabel canvas ?options?
39              Creates  a  canvasLabel  object  in the specified Tk canvas. The
40              canvasLabel object identifier is returned (referred to  as  can‐
41              vasLabelObject in this document).
42
43       switched::configure canvasLabelObject ?options?
44              Configures  a canvasLabel object or returns all the options with
45              their current values if no options are passed as parameters.
46
47       switched::cget canvasLabelObject option
48              Returns an option value for the specified canvasLabel object.
49
50       stooop::delete canvasLabelObject
51              Deletes the specified canvasLabel object.

58              tangle is taken into account. The default is center.
