Interface Summary
Interface	Description
CompositeFigure	A composite figure is composed of several child `Figure`s.
ConnectionFigure	A connection figure connects two figures with a `BezierPath`.
Constrainer	A constrainer constrains editing operations performed by `Tool`s and `Handle`s on a `DrawingView`.
DecoratedFigure	A decorated figure can be decorated with another `Figure`, for example to draw a border around the decorated figure.
Drawing	A drawing is a container for `Figure`s.
DrawingEditor	A drawing editor coordinates drawing tools and drawing views.
DrawingView	A drawing view paints a `Drawing` on a `JComponent`.
Figure	A figure is a graphical element of a `Drawing`.
ImageHolderFigure	The interface of a `Figure` which has some editable image contents.
TextHolderFigure	The interface of a `Figure` that has some editable text contents.

Class Summary
Class	Description
AbstractAttributedCompositeFigure	This abstract class can be extended to implement a `CompositeFigure` which has its own attribute set.
AbstractAttributedDecoratedFigure	This abstract class can be extended to implement a `DecoratedFigure` which has an attribute set.
AbstractAttributedFigure	This abstract class can be extended to implement a `Figure` which has its own attribute set.
AbstractCompositeFigure	This abstract class can be extended to implement a `CompositeFigure`.
AbstractConstrainer	This abstract class can be extended to implement a `Constrainer`.
AbstractDrawing	This abstract class can be extended to implement a `Drawing`.
AbstractFigure	This abstract class can be extended to implement a `Figure`.
AttributeKey<T>	An attribute key provides typesafe access to an attribute of a `Figure`.
AttributeKeys	Defines a put of well known `Figure` attributes.
BezierFigure	A `Figure` which draws an opened or a closed bezier path.
DefaultDrawing	A default implementation of `Drawing` useful for drawings which contain only a few figures.
DefaultDrawingEditor	A default implementation of `DrawingEditor`.
DefaultDrawingView	A default implementation of `DrawingView` suited for viewing drawings with a small number of figures.
DefaultDrawingViewBeanInfo
DefaultDrawingViewTransferHandler	Default TransferHandler for DrawingView objects.
DiamondFigure	A `Figure` with a diamond shape.
DrawingEditorProxy	DrawingEditorProxy.
EllipseFigure	A `Figure` with an elliptic shape.
FigureLayerComparator	A `Comparator` used to sort figures by their layer property.
GraphicalCompositeFigure	The GraphicalCompositeFigure fills in the gap between a CompositeFigure and other figures which mainly have a presentation purpose.
GridConstrainer	Constrains a point such that it falls on a grid.
GroupFigure	A `Figure` which groups a collection of figures.
ImageFigure	A default implementation of `ImageHolderFigure` which can hold a buffered image.
LabeledLineConnectionFigure	A LineConnection with labels.
LabelFigure	A LabelFigure can be used to provide more double clickable area for a TextHolderFigure.
LineConnectionFigure	A `ConnectionFigure` which connects two figures using a bezier path.
LineFigure	A `Figure` which draws a continuous bezier path between two points.
ListFigure	A ListFigure consists of a list of Figures and a RectangleFigure.
QuadTreeCompositeFigure	QuadTreeCompositeFigure.
QuadTreeDrawing	An implementation of `Drawing` which uses a `QuadTree` to provide a good responsiveness for drawings which contain many figures.
RectangleFigure	A `Figure` with a rectangular shape.
RoundRectangleFigure	A `Figure` with a rounded rectangular shape.
TextAreaFigure	A `TextHolderFigure` which holds multiple lines of text in a rectangular area.
TextFigure	A `TextHolderFigure` which holds a single line of text.
TriangleFigure	Implements a `Figure` with a triangular shape.

Package org.jhotdraw.draw Description

Defines a framework for structured drawing editors and provides default implementations.

Package Contents

All key contracts of the framework are defined by Java interfaces. For each interface exists an abstract class, which implements the event handling contract of the interface. And finally, there is at least one default implementation of each interface.

The key interfaces for the representation of a drawing are:

The key interface for displaying a drawing on screen is:

DrawingView

The key interfaces for editing a drawing are:

DrawingEditor
Tool (in sub-package "tool")
Handle (in sub-package "handle")
