public class TextCreationTool
extends CreationTool
implements java.awt.event.ActionListener

A tool to create figures which implement the TextHolderFigure interface, such as TextFigure. The figure to be created is specified by a prototype.

To create a figure using this tool, the user does the following mouse gestures on a DrawingView:

1. Press the mouse button over an area on the DrawingView on which there isn't a text figure present. This defines the location of the figure.

When the user has performed this mouse gesture, the TextCreationTool overlays a text field over the drawing where the user can enter the text for the Figure. Design Patterns

Framework
The text creation and editing tools and the TextHolderFigure interface define together the contracts of a smaller framework inside of the JHotDraw framework for structured drawing editors.
Contract: TextHolderFigure, TextCreationTool, TextAreaCreationTool, TextEditingTool, TextAreaEditingTool, FloatingTextField, FloatingTextArea.

Prototype
The text creation tools create new figures by cloning a prototype TextHolderFigure object.
Prototype: TextHolderFigure; Client: TextCreationTool, TextAreaCreationTool.
