We have released version 6.4.2 of FlowChart.NET. It contains several customer-requested features and improvements:

Fluent API
Extension methods in MindFusion.Diagramming.Fluent and MindFusion.Diagramming.Layout.Fluent namespaces add support for fluent programming style:

using MindFusion.Diagramming.Fluent;
using MindFusion.Diagramming.Layout.Fluent;
//...

diagram.Factory
	.CreateShapeNode(10, 10, 20, 20)
		.Brush(Color.LightGray)
		.Font("Arial", 12)
		.EnableStyledText(true)
		.Text("Task <i>1</i>")
		.ToolTip("This is the task");

new TreeLayout()
	.LevelDistance(20)
	.NodeDistance(20)
	.LinkStyle(TreeLayoutLinkType.Cascading3)
	.Arrange(diagram); 

DiagramLink improvements

• The component no longer keeps a separate segmentCount field, removing a common source of errors. The SegmentCount property now calculates its value from ControlPoints elements. The UpdateFromPoints(updateGroups, updateSegments) overload has been removed too.
• SegmentCount setter no longer refuses changing number of segments if auto-routing is enabled or the link is a self-loop.
• The new Spline element of LinkShape enumeration draws links as interpolating splines that pass through all of their control points:
  

Miscellaneous

• the ModifierKeyAction.ExtendSelection mode selects items within the lasso without deselecting old ones.
• the Visio Stencils import API provides access to BeginArrow and EndArrow values.
• The Visio Stencils import API provides access to Connection elements defined for a shape.
• It is now enough to set EnableStyledText to enable styled-text mode without having to also enable PolygonalTextLayout.
• Fixed bug where ItemAdded event wasn't raised for interactively drawn items.
• Miscellaneous UI control assemblies (NodeListView, LayerListView, Ruler, etc) have been merged into a single MindFusion.Diagramming.WinForms.Controls.dll.

Installer for the latest version can be downloaded here, or from the clients area on our site:

Updated assemblies are also available as MindFusion.Diagramming NuGet package.

Enjoy!
