Diagram Editor initialization

This article covers the process of displaying a Diagram Editor on a page. In order to initialize the editor, you need to include source files specific for Editor and use the DiagramEditor instance. In all other aspects the initialization stage is the same as for the Diagram component:

<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="../codebase/diagramWithEditor.js"></script>
<link rel="stylesheet" href="../codebase/diagramWithEditor.css">
</head>

<body>
<div id="editor_container"></div>
<script>
// preparing data
const data = [
{ id: 1, x: 100, y: 40, text: "Start", type: "start", height: 50 },
{ id: 2, x: 100, y: 170, text: "Operation 1", type: "output" },
{ id: 3, x: 100, y: 300, text: "Operation 2", type: "input" },
{ from: 1, to: 2 },
{ from: 2, to: 3 }
// more objects
];

// creating Diagram Editor
const editor = new dhx.DiagramEditor("editor_container", {
// config options
});

// loading data into the editor
editor.parse(data);
</script>
</body>
</html>

Including required code files

To create Diagram Editor, you need to include 2 source files on your page:

  • diagramWithEditor.js
  • diagramWithEditor.css

Make sure that you set correct relative paths to these files:

<script type="text/javascript" src="../codebase/diagramWithEditor.js"></script>
<link rel="stylesheet" href="../codebase/diagramWithEditor.css">

Initializing Diagram Editor

You can initialize a Diagram Editor in a container, in the document body, or in a layout cell.

Initialization in a container

To initialize Diagram Editor in a container, use the dhx.DiagramEditor constructor and pass the following two parameters to the constructor function:

  • a container to place Diagram Editor into, let's give it the "editor_container" id:
index.html
<div id="editor_container"></div>
  • an object with configuration properties. If this argument is not passed to the constructor, the default settings will be applied
index.js
const editor = new dhx.DiagramEditor("editor_container", {
type: "default" // "default" | "org" | "mindmap"
});

Initialization in the document body

It is also possible to skip setting a container for Diagram Editor and to add it right into the document's body:

const editor = new dhx.DiagramEditor(document.body, {
type: "default" // "default" | "org" | "mindmap"
});

Initialization in a layout cell

You can also initialize an editor inside a Layout cell. In this case use null instead of a container:

const editor = new dhx.DiagramEditor(null, {
type: "default" // "default" | "org" | "mindmap"
});
const layout = new dhx.Layout("layout", {
cols: [
{
id: "diagram_editor"
}
]
});

layout.getCell("diagram_editor").attach(editor);

Configuration properties

To change the configuration of the editor, you can specify the desired property in the config object passed as a second parameter of the constructor function.

const editor = new dhx.DiagramEditor("editor_container", {
type: "default", // "default" | "org" | "mindmap"
shapeBarWidth: 320,
lineGap: 20
});

Properties

Check the full list of configuration properties of Editor.

Loading data into Diagram Editor

It is possible to load an appropriate data set into the editor via the parse() method of the editor.
