canvasLabel - tkpiechart canvas label class SYNOPSIS
package require stooop 4.1 package require switched 2.2 package require tkpiechart 6.6 stooop::new canvasLabel canvas ?options? switched::configure canvasLabelObject ?options? switched::cget canvasLabelObject option stooop::delete canvasLabelObject _________________________________________________________________ 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. stooop::new canvasLabel canvas ?options? Creates a canvasLabel object in the specified Tk canvas. The canvasLabel object identifier is returned (referred to as canvasLabe- lObject in this document). 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 Returns an option value for the specified canvasLabel object. stooop::delete canvasLabelObject Deletes the specified canvasLabel object.
