DESCRIPTION¶
The canvasLabel class brings some Tk label widget functionality to the canvas
text item, such as a background and a border.
The canvasLabel is built with a bullet rectangle on the left side of the text.
The relief changes according to the select state, with a traditionally sunken
relief when selected.
The label has a specific tag, which can be used to retrieve the coordinates of
the object or move it, thanks to the canvas facilities.

- Creates a canvasLabel object in the specified Tk canvas. The canvasLabel
object identifier is returned (referred to as canvasLabelObject in

- switched::configure canvasLabelObject ?options?
- Configures a canvasLabel object or returns all the options with their
current values if no options are passed as parameters.
- switched::cget canvasLabelObject option
