Detailed Description

A diagram item that adds text to the canvas.

This class is a wrapper for the Tkinter.Canvas.create_text() function.

Note: Text will not scale with the reset of the diagram. You will need to adjust the font size and possibly the DiagramBuilder's scale adjustment (see DiagramBuilder.SetScaleAdjustment()) to make the text display as desired.
