This isn't a truly <i>minimal</i> demonstration of <b>GoJS</b>,
|
|
because we do specify a custom Node template, but it's pretty simple.
|
|
The whole source for the sample is shown below if you click on the link.
|
|
</p>
|
|
<p>
|
|
This sample sets the <a>Diagram.nodeTemplate</a>, with a <a>Node</a> template that data binds both the text string and the shape's fill color.
|
|
For an overview of building your own templates and model data, see the <a href="../learn/index.html">Getting Started tutorial.</a>
|
|
</p>
|
|
<p>
|
|
The <a>Diagram.initialContentAlignment</a> setting causes the diagram's contents
|
|
to appear in the center of the diagram's viewport.
|
|

|
Using the mouse and common keyboard commands, you can pan, select, move, copy, delete, and undo/redo.
|
|
On touch devices, use your finger to act as the mouse, and 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 the selected object.
