The pie peripheral 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 slice description text labels are arranged in 2 columns
below the pie graphics, whereas the slice values are placed next to
the slice and actually follow the slice as the pie is updated. Each
description label text is placed to the right of a rectangle, the
background color of which matches its corresponding slice. Each
description label is actually a canvasLabel object.
There is no need to delete a
piePeripheralLabeler object as it is automatically
handled by the pie class.
- stooop::new
piePeripheralLabeler canvas
?options?
- Creates a piePeripheralLabeler object in the specified Tk
canvas. The piePeripheralLabeler object identifier is returned
(refered to as piePeripheralLabelerObject in this
document).
- switched::configure piePeripheralLabelerObject ?options?
- Configures a piePeripheralLabeler object or returns all the
options with their current values if no options are passed as
parameters.
- switched::cget piePeripheralLabelerObject option
- Returns an option value for the specified piePeripheralLabeler
object.
- -font value
- Specifies a font for the slice labels. If not specified, the
default font is system dependent.
- -justify value
- Specifies how to justify labels within their own column. Must
be one of left, center or right.
Defaults to left. For example, if justification is
right, all column labels right edges are aligned.
- -offset value
- Specifies the distance between the pie graphics and the closest
slice label. This value may be specified in any of the forms
described in the canvas COORDINATES
manual section.
- -smallfont
- Specifies a font for the slice values. It is usually a small
font in order to avoid values overlapping when 2 slices are very
close to each other. If not specified, the description label font
(-font option) is used.
- -widestvaluetext
- Specifies a string of maximum width for slice values (placed
around the pie next to the slices), so that enough room is
allocated for these value labels when the pie width and height are
set. It defaults to 00.0. For example, it could be set to "00.00
%".
The labeler has the following specific tag (see the canvas manual page ITEM
