<div id="myDiagramDiv" style="border: solid 1px black; width:400px; height:400px"></div>
|

<p>
|
|
This sample demonstrates tooltips and context menus for all parts and for the diagram background,
|
|
as well as several other powerful diagram editing abilities.
|
|
</p>
|
|
<p>
|
|
Unlike the <a href="minimal.html">Minimal</a> sample, this sample has templates for Links and for Groups,
|
|
plus tooltips and context menus for Nodes, for Links, for Groups, and for the Diagram.
|
|
</p>
|
|
<p>This sample has all of the functionality of the Minimal sample, but additionally allows the user to:</p>
|
|
<ul>
|
|
<li>create new nodes: double-click in the background of the diagram</li>
|
|
<li>edit text: select the node and then click on the text, or select the node and press F2</li>
|
|
<li>draw new links: drag from the inner edge of the node's or the group's shape</li>
|
|
<li>reconnect existing links: select the link and then drag the diamond-shaped handle at either end of the link</li>
|
|
<li>group nodes and links: select some nodes and links and then type Ctrl-G (or invoke via context menu)</li>
|
|
<li>ungroup an existing group: select a group and then type Ctrl-Shift-G (or invoke via context menu)</li>
|
|
</ul>
|
|
<p>
|
|
GoJS contains many other possible commands, which can be invoked by either mouse/keyboard/touch or programatically.
|
|
<a href="../intro/commands.html">See an overview of possible commands here.</a>
|
|
On a Mac, use CMD instead of Ctrl.
|
|
</p>
|
|
<p>
|
|
On touch devices, hold your finger stationary to bring up a context menu.
|
|
The default context menu supports most of the standard commands that are enabled at that time for that object.
