An AddFlow diagram is a set of objects that can be linked each other. The objects are called nodes and the lines that connect objects are called links.

AddFlow provides two ways to build diagrams:

• Interactive way (with the mouse): see the Quick Start of the help file in order to know how to interactively draw a diagram
• Programmatic way with the AddFlow API

Following is a list of the main AddFlow features. Note that all those features are encapsulated in a small (375 Kb only), robust, fast and easy to use ActiveX component.

General

• Runtime-royalty free
• Digitally signed
• Interactive and programmatic drawings
• Navigation (You can access every nodes and links of a diagram with just 5 properties)
• Collections support (nodes, links, selected nodes, selected links)
• Customization: many properties allowing to customize the control (CanDrawNode, CanMoveNode, ReadOnly, etc...)

Input/output

• Metafiles support (WMF, EMF)
• Serialisation of diagrams (LoadFile, SaveFile methods)
• XML serialisation
• Clipboard management
• Printing and print previewing

Interactivity

• Scrolling (interactive and programmatic)

Data

• Ability to associate a text, a unique key, a tooltip and a tag to a node or a link

Links

• Stretchable links. A link can be composed of many segments

• Reflexive links
• Links having only vertical and horizontal segments
• Ability to adjust the position of the first and last point of a link
• 20 arrow styles for links
• Ability to customize the drawing of a link (OwnerDraw event)
• Link autorouting

Nodes

• Ability to customize the drawing of a node (OwnerDraw event)
• 46 distinct shapes for nodes
• Custom shapes
• Transparent nodes
• Text alignment
• Autosize options for nodes
• Gradient color

Automatic graph layout

AddFlow does not directly provide any automatic graph layout feature. However we provide LayoutFlow, a set of four AddFlow graph layout controls:

• HFlow (hierarchical layout)
• OFlow (orthogonal layout)
• SFlow (symmetric force directed layout)
• TFlow (tree layout)

A demonstration of each of these products is available in the LayoutDemo sample.
