Diagramming for JavaScript, V2.5

Posted on by

The new release of MindFusion Diagramming library for JavaScript contains some useful new features and improvements. Below are the details:

Resize of table columns and rows

Columns and rows of a TableNode can now be resized interactively if its AllowResizeColumns or AllowResizeRows properties are enabled. In order to resize, move the mouse pointer to the border line on column’s right side or row’s bottom side until it shows resize cursor and start dragging. The control raises tableColumnResizing and tableRowResizing events to let you validate new size or prevent resizing some elements. The tableColumnResized and tableRowResized events are raised after the operation completes.

Shape libraries

The ShapeLibrary class lets you use custom geometric shapes created using MindFusion ShapeDesigner tool. Call its loadFromXml method to load a library XML file. getShapes returns an array of the loaded Shape objects. The ShapeLibraryLocation property of NodeListView creates a prototype ShapeNode object for each shape from the specified library.

Miscellaneous

  • TextStroke and TextStrokeThickness properties of DiagramItem let you set color and thickness of text outlines.
  • Items can now be deleted using Backspace key when running on Mac.
  • Caption divider line in TableNode and ContainerNode is now rendered clipped when caption height is smaller than corner radius.
  • The TooltipDelay property specifies the delay in milliseconds before showing tooltips.
  • The Orientation property of NodeListView lets you set the view’s orientation to Horizontal or Vertical .
  • MindFusion.Common.js contains code shared with other JavaScript libraries by MindFusion. It must be loaded before the MindFusion.Diagramming.js script.

Fixed bugs

  • Fixed overlaps in TreeLayout when arranging nodes of different sizes.
  • Anchor points indices were not serialized and could be reset to different values when loading from JSON.
  • Deserialization of custom item classes worked correctly only if their names contained Node or Link suffix.

MindFusion.Diagramming for ASP.NET, V5.0.4 and MindFusion.Diagramming for ASP.NET MVC, V1.7

Posted on by

MindFusion has released beta versions of its Diagramming components for ASP.NET and ASP.NET MVC. Here is an overview of the most important new features added to both controls:

Import of Visio *.vsdx files

Use the new Visio2013Importer class to import any *.vsdx file created with Visio 2013 into your diagrams. First, you must add a reference to MndFusion.Diagramming.Import.Visio.dll assembly. Various overloads of the Import method let you choose how your Visio file will be presented – as a DiagramDocument, whose pages correspond to the Visio pages or as a single Diagram, whose content is merged from all Visio pages. Every node shape and connector from the Visio file is represented with a ShapeNode and DiagramLink object in the imported diagram. The Shape, Text, Brush and properties of each MindFusion.ShapeNode object and the Origin, Destination and ControlPoints properties of each MindFusion.DiagramLink object are set to values that make the imported links and nodes resemble as much as possible their Visio counterparts.

New predefined shapes

The Shapes class boasts a handful of new shapes – RightTriangle, Decagon, Trapezoid, Star4Pointed, Star5Pointed, Star6Pointed, Star7Pointed, Star16Pointed, Star24Pointed, Star32Pointed, Donut and Plaque.

Container nodes.

Container nodes.

New features only in MindFusion.Diagramming for ASP.NET MVC:

Adjustment handle styles.

You can customize the appearance of nodes’ adjustment handles with the HandlesStyle property. Choose among round and square handles, dashed and hatched frames, and some combinations. The handles style also sets what part of the node can be dragged, which moves or resizes it. You can even create your own custom handles.

Dynamic links

A dynamic link automatically changes its end segments to point to the centers of its target nodes when they are dragged around. If a node’s AnchorPattern is set, the ends of the dynamic link will align to the closest anchor point instead.

ContainerNode enhancements

  • You can apply layout algorithms to the content of a ContainerNode by calling its arrange method
  • The new containerChildAdding and containerChildRemoving events let you prevent adding or removing child nodes to/from a container

Every element in the diagram is easily accessible and the whole diagram is rendered as part of an HTML page by just calling the DiagramView extension method.
