These editing abilities are accessible via mouse (or touch) and keyboard by default, and can also be invoked programmatically in JavaScript. </p> <p> The following Diagram defines a node template and has four nodes in its model: </p> <pre class="lang-js"><code> const $ = go.GraphObject.make; const myDiagram = new go.Diagram("myDiagramDiv", { "undoManager.isEnabled": true }); // define a simple Node template myDiagram.nodeTemplate = $(go.Node, "Auto", $(go.Shape, "Rectangle", // don't draw any outline { stroke: null }, // the Shape.fill comes from the Node.data.color property new go.Binding("fill", "color")), $(go.TextBlock, // leave some space around larger-than-normal text { margin: 6, font: "18px sans-serif" }, // the TextBlock.text comes from the Node.data.text property new go.Binding("text")) ); myDiagram.model = new go.GraphLinksModel( [ // there will be a Node for each data object in this nodeDataArray { key: 1, text: "Alpha", color: "lightblue" }, { key: 2, text: "Beta", color: "orange" }, { key: 3, text: "Gamma", color: "lightgreen" }, { key: 4, text: "Delta", color: "pink" } ]); </code></pre> <!-- LIVE --> <div id="myDiagramDiv" class="diagramStyling" style="width:700px; height:150px"></div> <script> var $ = go.GraphObject.make; var myDiagram = new go.Diagram("myDiagramDiv", { "undoManager.isEnabled": true }); myDiagram.nodeTemplate = $(go.Node, "Auto", $(go.Shape, "Rectangle", { stroke: null }, new go.Binding("fill", "color")), $(go.TextBlock, { margin: 6, font: "18px sans-serif" }, new go.Binding("text")) ); myDiagram.model = new go.GraphLinksModel( [ // there will be a Node for each data object in this nodeDataArray { key: 1, text: "Alpha", color: "lightblue" }, { key: 2, text: "Beta", color: "orange" }, { key: 3, text: "Gamma", color: "lightgreen" }, { key: 4, text: "Delta", color: "pink" } ]); </script> <p> Out of the box, several interactions are available: </p> <ul> <li> Click a node to select it. Press and drag on a node to move it around. Or press and drag in the diagram background to pan the entire Diagram. </li> <li> Common keyboard shortcuts such as <code>Ctrl-C</code>, <code>Ctrl-V</code>, <code>Ctrl-X</code> will copy, paste, and cut diagram parts, respectively. Note that copies will copy the location of the Node as well, unless a layout or the paste command moves the new node. </li> <li> Drag-and-hold in the background of the diagram allows you to create a selection box for selecting multiple nodes. Ctrl-clicking on nodes allows you to toggle their selection. Shift-clicking on nodes makes sure they are selected. </li> <li> Since the Diagram's undoManager was enabled, <code>Ctrl-Z</code> and <code>Ctrl-Y</code> will undo and redo operations. Panning (scrolling) and selection are not considered undoable operations. </li> </ul> <p> By setting a few properties you can expose more interaction to a user, including manipulating groups: </p> <pre class="lang-js"><code> const $ = go.GraphObject.make; const myDiagram = new go.Diagram("myDiagramDiv", { // allow double-click in background to create a new node "clickCreatingTool.archetypeNodeData": { text: "Node", color: "lightgray" }, // allow Ctrl-G to group selected nodes "commandHandler.archetypeGroupData": { text: "Group", isGroup: true }, // have mouse wheel events zoom in and out instead of scroll up and down "toolManager.mouseWheelBehavior": go.ToolManager.WheelZoom, "undoManager.isEnabled": true // enable undo &amp; redo }); myDiagram.nodeTemplate = $(go.Node, "Auto", $(go.Shape, "Rectangle", { stroke: null }, new go.Binding("fill", "color")), $(go.TextBlock, { margin: 6, font: "18px sans-serif", editable: true }, new go.Binding("text").makeTwoWay()) ); myDiagram.groupTemplate = $(go.Group, "Vertical", { ungroupable: true }, // allow Ctrl-Shift-G to ungroup a selected Group. $(go.TextBlock, { font: "bold 12pt sans-serif" }, new go.Binding("text")), $(go.Panel, "Auto", $(go.Shape, { fill: "transparent" }), $(go.Placeholder, { padding: 10 }) ) ); myDiagram.model = new go.GraphLinksModel( [ { key: 1, text: "Alpha", color: "lightblue" }, { key: 2, text: "Beta", color: "orange" }, { key: 3, text: "Gamma", color: "lightgreen", group: 5 }, { key: 4, text: "Delta", color: "pink", group: 5 }, { key: 5, text: "Group1", isGroup: true } ]); </code></pre> <!-- LIVE --> <div id="myDiagramDiv2" class="diagramStyling" style="width:700px; height:250px"></div> <script> var $ = go.GraphObject.make; var myDiagram2 = new go.Diagram("myDiagramDiv2", { // allow double-click in background to create a new node "clickCreatingTool.archetypeNodeData": { text: "Node", color: "lightgray" }, // allow Ctrl-G to group selected nodes "commandHandler.archetypeGroupData": { text: "Group", isGroup: true }, // have mouse wheel events zoom in and out instead of scroll up and down "toolManager.mouseWheelBehavior": go.ToolManager.WheelZoom, "undoManager.isEnabled": true // enable undo & redo }); myDiagram2.nodeTemplate = $(go.Node, "Auto", $(go.Shape, "Rectangle", { stroke: null }, new go.Binding("fill", "color")), $(go.TextBlock, { margin: 6, font: "18px sans-serif", editable: true }, new go.Binding("text").makeTwoWay()) ); myDiagram2.groupTemplate = $(go.Group, "Vertical", { ungroupable: true }, // allow Ctrl-Shift-G to ungroup a selected Group. $(go.TextBlock, { font: "bold 12pt sans-serif" }, new go.Binding("text")), $(go.Panel, "Auto", $(go.Shape, { fill: "transparent" }), $(go.Placeholder, { padding: 10 }) ) ); myDiagram2.model = new go.GraphLinksModel( [ { key: 1, text: "Alpha", color: "lightblue" }, { key: 2, text: "Beta", color: "orange" }, { key: 3, text: "Gamma", color: "lightgreen", group: 5 }, { key: 4, text: "Delta", color: "pink", group: 5 }, { key: 5, text: "Group1", isGroup: true } ]); </script> <p> <ul> <li> <code>ClickCreatingTool.archetypeNodeData</code> allows a double-click in the background to create a new node with the specified data. </li> <li> <code>CommandHandler.archetypeGroupData</code> allows <code>Ctrl-G</code> to group a selection of nodes. </li> <li> <code>Group.ungroupable</code> allows <code>Ctrl-Shift-G</code> to ungroup a selected group. </li> <li> <code>ToolManager.mouseWheelBehavior</code> allows the mouse wheel to zoom instead of scroll by default. You can toggle this property by clicking on the mouse-wheel. On touch devices, pinch-zooming is enabled by default. </li> <li> <code>TextBlock.editable</code> in the <code>TextBlock</code> definition allows the text to be edited in place. Select a node and then click on the text, or press F2, to begin text editing. Click anywhere else on the diagram or press <code>Tab</code> to finish editing text. </li> </ul> </p> <p> These interactions (and more!) are all present in the <a href="../samples/basic.html">basic.html sample</a>. Be sure to also see the <a href="../intro/commands.html">Intro page on GoJS commands</a>. </p> <p> You can disable portions of Diagram interactivity with several properties, depending on what you want to allow users to do. See the <a href="../intro/permissions.html">Intro page on GoJS permissions</a> for more explanation. </p> <h2 id="ContextMenus">Context Menus</h2> <p> <b>GoJS</b> provides a mechanism for you to define context menus for any object or for the Diagram itself. In the example below, two context menus are defined, one on the Node template (with one button) and one on the Diagram (with two buttons). </p> <pre class="lang-js"><code> const $ = go.GraphObject.make; const myDiagram = new go.Diagram("myDiagramDiv", { "undoManager.isEnabled": true }); // this function is called when the context menu button is clicked function nodeClicked(e, obj) { alert('node ' + obj.part.data.key + ', "' + obj.part.data.text + '" was clicked'); } // defines a context menu to be referenced in the node template const contextMenuTemplate = $(go.Adornment, "Vertical", $("ContextMenuButton", $(go.TextBlock, "Click me!"), { click: nodeClicked }) // more ContextMenuButtons would go here ); myDiagram.nodeTemplate = $(go.Node, "Auto", { contextMenu: contextMenuTemplate }, // set the context menu $(go.Shape, "Rectangle", { stroke: null }, new go.Binding("fill", "color")), $(go.TextBlock, { margin: 6, font: "18px sans-serif" }, new go.Binding("text")) ); // this function alerts the current number of nodes in the Diagram function countNodes(e, obj) { alert('there are ' + e.diagram.nodes.count + ' nodes'); } // this function creates a new node and inserts it at the last event's point function addNode(e, obj) { const data = { text: "Node", color: "white" }; // do not need to set "key" property -- addNodeData will assign it automatically e.diagram.model.addNodeData(data); const node = e.diagram.findPartForData(data); node.location = e.diagram.lastInput.documentPoint; } myDiagram.contextMenu = $(go.Adornment, "Vertical", $("ContextMenuButton", $(go.TextBlock, "Count Nodes"), { click: countNodes }), $("ContextMenuButton", $(go.TextBlock, "Add Node"), { click: addNode }) // more ContextMenuButtons would go here ); myDiagram.model = new go.GraphLinksModel( [ { key: 1, text: "Alpha", color: "lightblue" }, { key: 2, text: "Beta", color: "orange" } ]); </code></pre> <!-- LIVE --> <div id="myDiagramDiv3" class="diagramStyling" style="width:700px; height:150px"></div> <script> var $ = go.GraphObject.make; var myDiagram3 = new go.Diagram("myDiagramDiv3", { "undoManager.isEnabled": true }); // this function is called when the context menu button is clicked function nodeClicked(e, obj) { alert('node ' + obj.part.data.key + ', "' + obj.part.data.text + '" was clicked'); } // defines a context menu to be referenced in the node template const contextMenuTemplate = $(go.Adornment, "Vertical", $("ContextMenuButton", $(go.TextBlock, "Click me!"), { click: nodeClicked }) // more ContextMenuButtons would go here ); myDiagram3.nodeTemplate = $(go.Node, "Auto", { contextMenu: contextMenuTemplate }, // set the context menu $(go.Shape, "Rectangle", { stroke: null }, new go.Binding("fill", "color")), $(go.TextBlock, { margin: 6, font: "18px sans-serif" }, new go.Binding("text")) ); // this function alerts the current number of nodes in the Diagram function countNodes(e, obj) { alert('there are ' + e.diagram.nodes.count + ' nodes'); } // this function creates a new node and inserts it at the last event's point function addNode(e, obj) { const data = { text: "Node", color: "white" }; // do not need to set "key" property -- addNodeData will assign it automatically e.diagram.model.addNodeData(data); const node = e.diagram.findPartForData(data); node.location = e.diagram.lastInput.documentPoint; } myDiagram3.contextMenu = $(go.Adornment, "Vertical", $("ContextMenuButton", $(go.TextBlock, "Count Nodes"), { click: countNodes }), $("ContextMenuButton", $(go.TextBlock, "Add Node"), { click: addNode }) // more ContextMenuButtons would go here ); myDiagram3.model = new go.GraphLinksModel( [ { key: 1, text: "Alpha", color: "lightblue" }, { key: 2, text: "Beta", color: "orange" } ]); </script> <p> If you right-click (or long-tap on a touch device) on a Node or the Diagram, you will see the <b>GoJS</b> context menu appear with the defined options. </p> <p> The <a href="../samples/basic.html">basic.html sample</a> contains more complex context menu examples. See the <a href="../intro/contextmenus.html">Intro page on GoJS context menus</a> for more discussion. </p> <h2 id="LinkInteractions">Link interactions</h2> <p> <b>GoJS</b> lets users draw new links by dragging out from a port. Users can reconnect existing links by selecting one and dragging one of its handles. To enable these tools, some properties need to be set: </p> <pre class="lang-js"><code> const $ = go.GraphObject.make; const myDiagram = new go.Diagram("myDiagramDiv", { "undoManager.isEnabled": true }); myDiagram.nodeTemplate = $(go.Node, "Auto", $(go.Shape, "Rectangle", { stroke: null, portId: "", cursor: "pointer", fromLinkable: true, fromLinkableSelfNode: true, fromLinkableDuplicates: true, toLinkable: true, toLinkableSelfNode: true, toLinkableDuplicates: true }, new go.Binding("fill", "color")), $(go.TextBlock, { margin: 6, font: "18px sans-serif" }, new go.Binding("text")) ); myDiagram.linkTemplate = $(go.Link, { // allow the user to reconnnect existing links: relinkableFrom: true, relinkableTo: true, // draw the link path shorter than normal, // so that it does not interfere with the appearance of the arrowhead toShortLength: 2 }, $(go.Shape, { strokeWidth: 2 }), $(go.Shape, { toArrow: "Standard", stroke: null }) ); myDiagram.model = new go.GraphLinksModel( [ { key: "Alpha", color: "lightblue" }, { key: "Beta", color: "orange" }, { key: "Gamma", color: "lightgreen" }, { key: "Delta", color: "pink" } ], [ { from: 1, to: 2 }, { from: 1, to: 4 } ]); </code></pre> <!-- LIVE --> <div id="myDiagramDiv4" class="diagramStyling" style="width:700px; height:150px"></div> <script> var $ = go.GraphObject.make; var myDiagram4 = new go.Diagram("myDiagramDiv4", { "undoManager.isEnabled": true }); myDiagram4.nodeTemplate = $(go.Node, "Auto", $(go.Shape, "Rectangle", { stroke: null, portId: "", cursor: "pointer", fromLinkable: true, fromLinkableSelfNode: true, fromLinkableDuplicates: true, toLinkable: true, toLinkableSelfNode: true, toLinkableDuplicates: true }, new go.Binding("fill", "color")), $(go.TextBlock, { margin: 10, font: "18px sans-serif" }, new go.Binding("text")) ); myDiagram4.linkTemplate = $(go.Link, { // allow the user to relink existing links: relinkableFrom: true, relinkableTo: true, // draw the link path shorter than normal, // so that it does not interfere with the appearance of the arrowhead toShortLength: 2 }, $(go.Shape, { strokeWidth: 2 }), $(go.Shape, { toArrow: "Standard", stroke: null }) ); myDiagram4.model = new go.GraphLinksModel( [ { key: 1, text: "Alpha", color: "lightblue" }, { key: 2, text: "Beta", color: "orange" }, { key: 3, text: "Gamma", color: "lightgreen" }, { key: 4, text: "Delta", color: "pink" } ], [ { from: 1, to: 2 }, { from: 1, to: 4 } ]); </script> <p> In the above example: </p> <ul> <li> The Node's <code>Shape</code> has its <code>portId</code> set to make it the port instead of the entire Node. Then several <code>...Linkable</code> properties are set, allowing each node to link to itself and to others. You may not need to set all of those properties on your ports in your node templates. </li> <li> To create a new link to another node, drag from the port (the edge of the Shape that is not behind the TextBlock) to any node, including itself. </li> <li> In the link template, <code>relinkable...</code> properties are set, so that when the link is selected, it shows handles that can be dragged in order to reconnect the link with a different node. </li> </ul> <p> <b>GoJS</b> allows linking and re-linking to abide by custom criteria in which source and destination nodes are valid.
