TFlow for .Net Details

TFlow for .NET is a .NET component. It provides the same features as the ActiveX version. The following code is all you need to do to perform a tree layout on a graph:

• Dim tflow As TFlow = New TFlow()
• tflow.LayerDistance = 1000 ‘ Sets the distance between adjacant levels
• tflow.VertexDistance = 1000 ‘ Sets the distance between adjacant vertices
• tflow.Orientation = Orientation.North
• tflow.Layout(AddFlow1) ‘ Perform the tree layout

This code supposes that you have a form containing an AddFlow control. In this example, the TFlow component is created dynamically. You create the graph in the AddFlow control, either interactively or programmatically (in this case, giving each vertex a random position or a (0,0) position). Then you apply the TFlow layout to this graph.

Only the logical vertices and edges of the AddFlow control are involved in this layout. This will allow you to apply the layout only to important vertices. For instance, you can exclude a node just used to display a label by setting its Logical property to false.

What's New in V2.0

The possibility to obtain radial drawing of tree diagrams - More precisely, if the DrawingStyle property value is DrawingStyle.Layered, the vertices at the same level of the tree are placed on the same line and the parent is centered over its children. If the DrawingStyle property value is DrawingStyle.Radial, the root is placed at the origin and layers are concentric circles centered at the origin.

Notice that it is necessary to use AddFlow for .NET to be able to use Tflow for .NET. Both products are installed via a common installation program.
