Connector in Vue Diagram component

29 Jul 2021 / 30 minutes to read

Connectors are objects used to create link between two points, nodes or ports to represent the relationships between them.

Create Connector

Connector can be created by defining the source and target point of the connector. The path to be drawn can be defined with a collection of segments. To explore the properties of a connector, refer to Connector Properties.

Add connectors through connectors collection

The sourcePoint and targetPoint properties of connector allow you to define the end points of a connector.

The following code example illustrates how to add a connector through connector collection.

Connectors from palette

Connectors can be predefined and added to the symbol palette. You can drop those connectors into the Diagram, when required.

For more information about adding connectors from symbol palette, refer to [Symbol Palette].

Draw connectors

Connectors can be interactively drawn by clicking and dragging on the Diagram surface by using [drawingObject]. For more information about drawing connectors, refer to Draw Connectors.

Update Connector at runtime

Various Connector properties such as sourcePoint, targetPoint,style,sourcePortID,targetPortID etc can be update at the run time .

The following code example illustrates how to update a connector’s source point,target point,styles properties at runtime.

When you remove NodeConstraints InConnect from Default, the node accepts only an outgoing connection to dock in it. Similarly, when you remove NodeConstraints OutConnect from Default, the node accepts only an incoming connection to dock in it.
When you remove both InConnect and OutConnect NodeConstraints from Default, the node restricts connector to establish connection in it.
The following code illustrates how to disable InConnect constraints.

//Initialize diagram
let diagram: Diagram = new Diagram({
 nodes:[
     {
        id: 'node', width: 100, height: 100, offsetX: 100, offsetY: 150,
        shape: { type: 'Basic', shape: 'Rectangle' },
        //Disable InConnect constraints
        constraints: NodeConstraints.Default & ~NodeConstraints.InConnect,
     }
 ]
});
diagram.appendTo('#diagram');

Connections with ports

The sourcePortID and targetPortID properties allow to create connections between some specific points of source/target nodes.

The following code example illustrates how to create port to port connections.

When you set PortConstraints to InConnect, the port accepts only an incoming connection to dock in it. Similarly, when you set PortConstraints to OutConnect, the port accepts only an outgoing connection to dock in it.
When you set PortConstraints to None, the port restricts connector to establish connection in it.

//Initialize diagram
let diagram: Diagram = new Diagram({
 nodes:[
     {
        id: 'node', width: 100, height: 100, offsetX: 100, offsetY: 150,

       ]
     }
 ]
});
diagram.appendTo('#diagram');

Segments

The path of the connector is defined with a collection of segments. There are three types of segments.

Straight

To create a straight line, you should specify the type of the segment as “straight” and add a straight segment to segments collection and need to specify type for the connector. The following code example illustrates how to create a default straight segment.

Orthogonal

Orthogonal segments are used to create segments that are perpendicular to each other.

Set the segment type as “orthogonal” to create a default orthogonal segment and need to specify type. The following code example illustrates how to create a default orthogonal segment.

Multiple segments can be defined one after another. To create a connector with multiple segments, define and add the segments to connector.segments collection. The Following code example illustrates how to create a connector with multiple segments.

Note: We need mention the segment type as same as what we mentioned in connector type. There should be no contradiction between connector type and segment type.

Avoid overlapping

Orthogonal segments are automatically re-routed, in order to avoid overlapping with the source and target nodes. The following preview illustrate how orthogonal segments are re-routed.

Bezier

Bezier segments are used to create curve segments and the curves are configurable either with the control points or with vectors.

To create a bezier segment, the segment.type is set as bezier and need to specify type for the connector. The following code example illustrates how to create a default Bezier segment.

Decorator

Start and end points of a connector can be decorated with some customizable shapes like arrows, circles, diamond or path. You can decorate the connection end points with the sourceDecorator and targetDecoratorproperties of connector.
The shape property of sourceDecorator allows to define the shape of the decorators. Similarly, the shape property of targetDecorator allows to define the shape of the decorators.
To create custom shape for source decorator, use pathData property. similarly, to create custom shape for target decorator, use pathData property.
The following code example illustrates how to create decorators of various shapes.

Padding

Padding is used to leave the space between the Connector’s end point and the object to where it is connected.

The sourcePadding property of connector defines space between the source point and the source node of the connector.
The targetPadding property of connector defines space between the end point and the target node of the connector.
The following code example illustrates how to leave space between the connection end points and source and target nodes.

Flip

The diagram Provides support to flip the connector. The flip is performed to give the mirrored image of the original element.

The flip types are as follows:

HorizontalFlip Horizontal is used to interchange the connector source and target x points.
VerticalFlip Vertical is used to interchange the connector source and target y points.
Both Both is used to interchange the source point as target point and target point as source point

Bridging

Line Bridging creates a bridge for lines to smartly cross over other lines, at points of intersection. By default bridgeDirection is set to top. Depending upon the direction given bridging direction appears. Bridging can be enabled/disabled either with the [connector.constraints] or [diagram.constraints]. The following code example illustrates how to enable line bridging.

Note: We Need to inject Connector bridging module into the diagram.

You can use bridgeSpace property of connectors to define the width for line bridging.

Limitation: Bezier segments do not support bridging.

Corner radius

Corner radius allows to create connectors with rounded corners. The radius of the rounded corner is set with cornerRadius property.

Appearance

The Connector’s strokeWidth, strokeColor, strokeDashArray and opacity properties are used to customize the appearance of the connector segments.
The visible property of the connector enables or disables the visibility of connector.
Default values for all the connectors can be set using the getConnectorDefaults properties. For example, if all connectors have the same type or having the same property then such properties can be moved into getConnectorDefaults.

Segment Appearance

The following code example illustrates how to customize the segment appearance.

Decorator Appearance

The source decorator’s strokeColor, strokeWidth and strokeDashArray properties are used to customize the color and width and appearance of the decorator.
To set the border stroke color, stroke width and stroke dash array for the target decorator, use strokeColor, strokeWidth and strokeDashArray.
To set the size for source decorator, use width and height property. Similarly, to set the size for target decorator, use width and height.

The following code example illustrates how to customize the appearance of the decorator.

Interaction

Diagram allows to edit the connectors at runtime. To edit the connector segments at runtime, refer to Connection Editing.

Automatic line routing

Diagram provides additional flexibility to re-route the diagram connectors. A connector will frequently re-route itself when a shape moves next to it. The following screenshot illustrates how the connector automatically re-routes the segments.

Dependency LineRouting module should be injected to the application as the following code snippet.

<script>
import {DiagramPlugin,LineRouting,Diagram,DiagramConstraints } from '@syncfusion/ej2-vue-diagrams';
Diagram.Inject(LineRouting);
Vue.use(DiagramPlugin);
</script>

Now, the line routing constraints must be included to the default diagram constraints to enable automatic line routing support like below.

/**
 *  Initialize the Diagram
 */
  <ejs-diagram #diagram [constraints]='constraints'>

  <template>
  <div id="app">
    <ejs-diagram   :constraints='constraints' ></ejs-diagram>
</div>
</template>

<script>
  // Enable line routing constraints.
let  constraints = DiagramConstraints.Default | DiagramConstraints.LineRouting;

</script>

The following code block shows how to create the diagram with specifying nodes, connectors, constraints, and necessary modules for line routing.

In some situations, automatic line routing enabled diagram needs to ignore a specific connector from automatic line routing. So, in this case, auto routing feature can be disabled to the specific connector using the constraints property of the connector like the following code snippet.

Constraints

The constraints property of connector allows to enable/disable certain features of connectors.
To enable or disable the constraints refer constraints

The following code illustrates how to disable selection.

Custom Properties

The addInfo property of connectors allows to maintain additional information to connectors.

let connectors: ConnectorModel = {
id: 'connector1',
// Defines the information about the connector
addInfo:'centralconnector',
type: 'Straight',
sourceID: 'Transaction',
targetID: 'Verification'
};

Stack Order

The connectors zIndex property specifies the stack order of an connector. A connector with greater stack order is always in front of an connector with a lower stack order.

The following code illustrates how to render connector based on the stack order.
