Diagram Library for Java Swing, V4.3

We have released the new version of the Java Diagram library. Here is a brief summary of the new features:

Fluent API

Builder classes in com.mindfusion.diagramming.builders package add support for fluent programming style. Static with and instance init methods in DiagramItem, DiagramItemStyle and Layout -derived classes return a builder instance that can be used to set up respective new or existing objects.

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:

Enum types

Old-style enumeration classes with static finals have been replaced by enum types, improving type checking and auto-completion support. This change will not affect your code if only passing enum members to methods from the API. If storing them in fields on the other hand, you must change the field type from int to respective enum type.

Several bug fixes
We have fixed a setLicenseKey problem and a bug with the SvgExporter.

You can find details about the new release at the official announcement page here.

Each chart type exposes numerous options to be customized in order to answer fully the requirements of the user. The control is packed with many samples that demonstrate different aspects of a chart type and offer ready-to-use code. The API is documented in details, with helpful tutorials and guides.

The chart component supports flexible data interface, which allows any data source to be used as a provider of chart data as long as it implements the Series interface. Predefined are a set of the most common data sources like XML, numeric lists, DateTime values, SQL database fields.

The innovative approach to styling lets developers control each aspect of the chart’s looks. They can alter the styling on the tiniest elements or concentrate on the bigger picture and create a global theme which can be reused.

Design custom shapes with WPF Diagram

Watch here the video for this tutorial.

This tutorial will run you through the process of creating custom WPF diagram shapes using the built-in Shape Designer. Keep in mind that the Designer is intended as a sample and is limited in terms of functionality. The designer is available inside the installation of MindFusion.Diagramming for WPF but is also included in this tutorial for convenience. For the purposes of this tutorial, we will create an ‘AND Gate’ circuit diagram shape as illustrated by the following image:

Circuit shapes

Run the Shape Designer application through the ShapeDesign.exe. The Shape Designer opens up with a single rectangular shape ready to be modified.

Diagramming WPF Circuit Shapes 1

The Shape Designer does not currently support shape renaming (remember, it’s just a sample), therefore create a new shape through the Shapes menu and name it ‘AndGate’.

Diagramming WPF Circuit Shapes 2

Select the newly created shape from the list on the left. In the editor select the right segment of the shape’s rectangle and press the DEL button on the keyboard. This will delete the segment and make the shape triangular.

Diagramming WPF Circuit Shapes 3

Adjust the end points of the shape segments so that it gets deflated on both sides. To adjust a segment, hover it with the mouse (so that its adjustment handles appear), then drag the handles.

Diagramming WPF Circuit Shapes 4

Select the arc primitive from the list on the right side of the screen. Drag this primitive over the top segment of the shape (until it gets highlighted in red) then drop.

Diagramming WPF Circuit Shapes 5

This will replace the line segment with an arc. Repeat the same process for the bottom segment of the shape.

Diagramming WPF Circuit Shapes 6

Adjust the middle point of both segments so that the shape looks protruded. Then drag three line primitives from the list on the right to the editor pane. Be careful not to drop the primitives over existing elements because this will replace the elements.

Diagramming WPF Circuit Shapes 7

Align the newly created line primitives with the existing shape.

Diagramming WPF Circuit Shapes 8

From the list with anchor points at the right side of the application, drag two anchor points from the first kind (input only) and one anchor point from the second kind (output only) and drop them inside the editor. Align the anchor points with the end points of the line segments created in the previous step.

Diagramming WPF Circuit Shapes 9

This will conclude the creation of the ‘AND Gate’ shape. You can test the shape in the preview diagram at the bottom of the screen.

Diagramming WPF Circuit Shapes 10

Save the shape library. Using the same approach, recreate the other circuit shapes from the image above. The following screenshot illustrates the complete library.

Diagramming WPF Circuit Shapes 11

The shape designer along with the shape library containing the circuit shapes can be downloaded from the link below:

MindFusion ASP.NET Diagram Control, V5.6

MindFusion is proud to present you with the new version of its ASP.NET diagram control.

Below you can read about the recently added features. As always, your questions are welcome. Use the technical support e-mail or MindFusion ASP.NET diagram forum.

Free-form nodes

A FreeFormNode collects all points from users’ mouse or touch input and displays them as node’s outline. To let users draw free-form nodes interactively, set Behavior to DrawFreeForms or LinkFreeForms.. Use the Points property of FreeFormNode to get or set outline points programmatically. If the Closed property is set, the node is drawn as a closed shape and its interior filled, or otherwise the node is drawn as a poly-line. If the distance between first and last points drawn by user is shorter than AutoCloseDistance, the node’s Closed property is automatically set to true. AutoCloseDistance¬† default value is float.MaxValue, so free-form nodes are always closed.

Free form nodes allow the user to draw diagram shapes with the mouse of the finger

Convert free-form drawings to ShapeNodes

Additional drawing modes, convenient for touch input, convert FreeFormNode objects drawn by user to ShapeNode objects with matching shapes. To enable them, set Behavior to DrawFreeShapes or LinkFreeShapes. The shapes against which the user’s input is matched are set via diagram’s FreeFormTargets property. By default it contains Rectangle, Decision and Ellipse shapes.

Miscellaneous

  • NodePastedScript and LinkPastedScript client-side events raised when items are pasted from the clipboard.
  • PdfExporter now creates page hyperlinks if HyperLink is set to a value in “page://{number}” format, e.g. set “page://1” to open the second PDF page when the item is clicked
  • TypeScript definitions for the client-side Diagramming API are now provided in jsdiag.d.ts file.

Fixed bugs

  • CanvasVirtualScroll mode fixed for parent div size specified in percent units.
  • Fixed bug where the ExpandOnIncoming property specifying link direction for collapse/expand actions did not work correctly.
  • Removed several global JavaScript variables created inadvertently by the control.
  • Fixed bug where¬†ShapeNodes’ Image did not zoom correctly in ImageMap mode for some ImageAlign values.
