Nevron Diagram for .NET - New Features in 2009 Vol.1 Release



DOM Improvements

  • Groups - Support for expandable/collapsible shapes (groups).

  • Decorators - Support for shape decorators. In this release we have implemented the following decorators:
    - Frame Decorator - adds a header and background to a shape.
    - Expand Collapse Decorator - adds an expand/collapse toggle button to a shape.
    - Show Hide Subtree Decorator - adds a show/hide subtree toggle button to a shape.

  • Support for Table Shapes - Table shapes are similar to the tables used in HTML (i.e. each cell can span several rows and/or columns, and may contain images and/or text).

  • Support for UML Shapes - Built upon the Table Shape, they allow the user to create UML class diagrams with ease. The UML shapes also supports different notations for its UML members.

  • Support for ERM Shapes and Connectors - With ERM Shapes and Connectors you can easily display any Entity Relation diagram.


Diagram Layout Improvements

  • The Balloon Tree Layout supports properties to control the sector angle for the children of the root vertex and the children of the other vertices, as well as the start angle at which to begin the layouting of the shapes.

  • The Radial and the Single Cycle Layouts allow the user to control their aspect ratio.

  • The Tip-over Tree Layout supports a different placement specifier for the tree leafs.

  • The Layered Graph Layout allows the user to specify the position of each node in its layer individually using its Layout Data.

  • The Layout Context allows the user to specify the shapes and/or groups he wants to layout.


New Diagram Importers (Database and Class Importers)

  • The Database Importer allows the users to import the entire hierarchy of a database, which makes the task of creating database entity relation diagrams easier than ever before.

  • The Class Importer allows the users to create complete class hierarchy diagrams based on a given class with only few lines of code.


Fixed Issues and Optimizations

  • The hit test of diagrams with thousands of shapes has been significantly optimized.

  • The cloning and binary serialization of user defined tags has been fixed.

  • The Disconnected event is now raised when you remove a connected shape.

  • The Random Graph Generator now always generates connected graphs.
