mxShape

Base class for all shapes.  A shape in mxGraph is a separate implementation for SVG, VML and HTML.  Which implementation to use is controlled by the dialect property which is assigned from within the mxCellRenderer when the shape is created.  The dialect must be assigned for a shape, and it does normally depend on the browser and the confiuration of the graph (see mxGraph rendering hint).

For each supported shape in SVG and VML, a corresponding shape exists in mxGraph, namely for text, image, rectangle, rhombus, ellipse and polyline.  The other shapes are a combination of these shapes (eg. label and swimlane) or they consist of one or more (filled) path objects (eg. actor and cylinder).  The HTML implementation is optional but may be required for a HTML-only view of the graph.

Custom Shapes

To extend from this class, the basic code looks as follows.  In the special case where the custom shape consists only of one filled region or one filled region and an additional stroke the mxActor and mxCylinder should be subclassed, respectively.

function CustomShape() { }

CustomShape.prototype = new mxShape();
CustomShape.prototype.constructor = CustomShape;

To register a custom shape in an existing graph instance, one must register the shape under a new name in the graph’s cell renderer as follows:

mxCellRenderer.registerShape('customShape', CustomShape);

The second argument is the name of the constructor.

In order to use the shape you can refer to the given name above in a stylesheet.  For example, to change the shape for the default vertex style, the following code is used:

var style = graph.getStylesheet().getDefaultVertexStyle();
style[mxConstants.STYLE_SHAPE] = 'customShape';
