Overview

TWiki:Main.PeterThoeny

JHotDraw is a simple drawing editor that supports drawing in a style similar to that found in MS Powerpoint and MS Word. Various shaped figures can be placed in the drawing and text annotations joined to them.

Unique to TWikiDrawPlugin, a drawing can also have a "map" which makes figures in the drawing sensitive to the mouse cursor. A map is automatically added to an image when a URL is attached to any of the figures.

How you edit a drawing depends on whether the drawing has a map and the setting of the "EDIT_BUTTON" option. A drawing with no map can be edited simply by clicking on the drawing. A drawing with a map can be edited by clicking the edit button or, failing that, on the boundary of the image.

Browser support for Java 1.1 or later required.

Syntax Rules

Write the command %DRAWING{name}% anywhere in a TWiki topic. You can name the drawing anything you like, allowed characters are A-Z, a-z, 0-9, ., _, -. If you have only one drawing in the topic you can simply write %DRAWING% .

Example: %DRAWING{workflow}%

Tools

The tools on the left create or manipulate figures.

	selects, moves or resizes a figure; the shift-key toggles the selection. Dragging the selection tool in the background selects the figures within the dragged rectangle.
	creates a new or edits an existing text figure
	creates a new text figure and attaches it to the clicked figure. Once a text figure is attached it remains connected to the figure.
	creates a rectangle figure
	creates a round rectangle figure
	creates an ellipse figure
	creates a line figure
	creates or adjusts connections between figures. A connection is split into segments by dragging a point on the connection. To join two segments click the end point of a segment
	creates an elbow connection and offers the same features as the ordinary connection tool
	creates a scribble figure; dragging the mouse creates a smooth line while successive clicks yields a polyline figure. A two-button click terminates the figure.
	creates a polygon figure; dragging the mouse creates a smooth border while successive clicks yields a polyline border. A two-button click or the ESCAPE key terminates the figure.
	decorates the clicked figure with a border
	adds a sensitive area to the figure that will redirect to a URL. If an image contains any sensitive areas it can only be selected for edit by clicking on the boundary or (if enabled) the attached Edit button. You can use wikiwords and web.topic wiki link expressions as well as full URLs.

Handles

When selected, figures provide different handles to manipulate them.

• the white squares let you to manipulate the shape of a figure
• the green squares on connections let you to reconnect them with another figure.
• the yellow circles on polygon figures let you change the size and rotation of the figure
• yellow circles on rounded rectangles let you change the radius of the corners
• the yellow circles on connections let you manipulate the position of connection segments.

Commands

Commands are invoked from the button bar at the bottom or from the menu bar at the top.

The standard commands that are provided include cut, copy, paste, duplicate, delete, group, ungroup, bring to front, and send to back.

Attributes

Attributes, such as fill color, text color or arrow tip, can be changed through the attributes menus.

Plugin Settings

NOTE: Do not change the settings here, overload them in the Main.TWikiPreferences. Prefix a setting with TWIKIDRAWPLUGIN_, e.g. to overload EXTRA_COLORS define a TWIKIDRAWPLUGIN_EXTRA_COLORS setting in the Main.TWikiPreferences.

• One line description, is shown in the TextFormattingRules
  • Set SHORTDESCRIPTION = Vector drawing editor and clickable maps for diagrams and workflows

• Extra colors to be added to the menu of colors in the applet, as a comma-separated list with colors in HTML format (see StandardColors)
  • Set EXTRA_COLORS = Aquamarine=#70DB93,New Tan=#EBC79E,Sea Green=#238E68,Motorola Blue=#3ff

• Set to 1 if an "Edit" button is to be generated attached to the image. You will still be able to edit it by clicking on the boundary of the image.
  • Set EDIT_BUTTON = 1

• Edit text defined here so you can change it for local languages. Text is shown when you hover over the image, and for the edit button. %F% will be replaced by the drawing name.
  • Set EDIT_TEXT = Edit drawing '%F%' (requires a Java 1.1 enabled browser)

Example Drawing

Here's an example using an image map. Move the mouse over the image and watch the status bar.
