## Table Of Contents

## Synopsis

- stooop::new pieBoxLabeler canvas ?options?
- switched::configure pieBoxLabelerObject ?options?
- switched::cget pieBoxLabelerObject option

## Description

The pie box style labeler object is used as a slice label placer for a pie object and is passed to the pie constructor via its -labeler option (see the pie class manual).

The labels are arranged in 2 columns below the pie graphics. Each label text is placed to the right of a rectangle, the background color of which matches its corresponding slice. The slice share value is placed to the right of the label text, separated by a semicolon. Each label is actually a canvasLabel object (see the canvasLabel class manual for further information).

There is no need to delete a pieBoxLabeler object as it is automatically handled by the pie class.

stooop::new pieBoxLabeler canvas ?options?

  Creates a pieBoxLabeler object in the specified Tk canvas. The pieBoxLabeler object identifier is returned (referred to as pieBoxLabelerObject in this document).

switched::configure pieBoxLabelerObject ?options?

  Configures a pieBoxLabeler object or returns all the options with their current values if no options are passed as parameters.

switched::cget pieBoxLabelerObject option

  Returns an option value for the specified pieBoxLabeler object.

## OPTIONS
