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.

Constructor Detail

TextCreationTool

public TextCreationTool(TextHolderFigure prototype)

Creates a new instance.

TextCreationTool

public TextCreationTool(TextHolderFigure prototype,
                        java.util.Map<AttributeKey,java.lang.Object> attributes)

Creates a new instance.

Method Detail

deactivate

public void deactivate(DrawingEditor editor)

Description copied from interface: Tool

Deactivates the tool. This method is called whenever the user switches to another tool.

Specified by:

deactivate in interface Tool

Overrides:

deactivate in class CreationTool

mousePressed

public void mousePressed(java.awt.event.MouseEvent e)

Creates a new figure at the location where the mouse was pressed.

Specified by:

mousePressed in interface java.awt.event.MouseListener

Overrides:

mousePressed in class CreationTool

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent e)

Specified by:

mouseDragged in interface java.awt.event.MouseMotionListener

Overrides:

mouseDragged in class CreationTool

beginEdit

protected void beginEdit(TextHolderFigure textHolder)

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent evt)

Specified by:

mouseReleased in interface java.awt.event.MouseListener

Overrides:

mouseReleased in class CreationTool

endEdit

protected void endEdit()

keyReleased

public void keyReleased(java.awt.event.KeyEvent evt)

Specified by:

keyReleased in interface java.awt.event.KeyListener

Overrides:

keyReleased in class AbstractTool

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent event)

Specified by:

actionPerformed in interface java.awt.event.ActionListener

creationFinished

protected void creationFinished(Figure createdFigure)

Description copied from class: CreationTool

This method allows subclasses to do perform additonal user interactions after the new figure has been created. The implementation of this class just invokes fireToolDone.

Overrides:

creationFinished in class CreationTool

isEditing

public boolean isEditing()

updateCursor

public void updateCursor(DrawingView view,
                         java.awt.Point p)

Overrides:

updateCursor in class CreationTool
