// CombineShape
function CombineShape()
{
mxRectangle.call(this);
};
mxUtils.extend(CombineShape, mxRectangle);
CombineShape.prototype.paintVertexShape = function(c, x, y, w, h)
{
c.begin();
c.moveTo(x, y);
c.lineTo(x + w, y);
c.lineTo(x + w / 2, y + h / 2);
c.close();
c.fillAndStroke();
c.begin();
c.moveTo(x, y + h);
c.lineTo(x + w, y + h);
c.lineTo(x + w / 2, y + h / 2);
c.close();
c.fillAndStroke();
};
mxCellRenderer.registerShape('combine', CombineShape);
To expand the range of shapes available, you have the option of either creating a new sidebar palette or integrating custom shapes into an existing one
For instance:
Suppose you wish to introduce new shapes to the Basic palette, navigate to your Sidebar.js file and locate the function
Sidebar.prototype.addBasicPalette/**
* Incorporates the general palette into the sidebar.
*/
Sidebar.prototype.addBasicPalette = function(dir)
{
this.addStencilPalette('basic', mxResources.get('basic'), dir + '/basic.xml',
';whiteSpace=wrap;html=1;fillColor=#ffffff;strokeColor=#000000;strokeWidth=2',
null, null, null, null, [
this.createVertexTemplateEntry('shape=partialRectangle;whiteSpace=wrap;html=1;top=0;bottom=0;fillColor=none;', 120, 60, '', 'Partial Rectangle'),
this.createVertexTemplateEntry('shape=partialRectangle;whiteSpace=wrap;html=1;right=0;top=0;bottom=0;fillColor=none;routingCenterX=-0.5;', 120, 60, '', 'Partial Rectangle'),
this.createVertexTemplateEntry('shape=partialRectangle;whiteSpace=wrap;html=1;bottom=0;right=0;fillColor=none;', 120, 60, '', 'Partial Rectangle'),
this.createVertexTemplateEntry('shape=partialRectangle;whiteSpace=wrap;html=1;top=0;left=0;fillColor=none;', 120, 60, '', 'Partial Rectangle'),
this.createEdgeTemplateEntry('html=1;verticalAlign=bottom;endArrow=block;', 80, 0, 'is_a', 'Is_A', null, 'uml sequence message call invoke dispatch'),
// New arrow named 'is_a' added above for reference
]);
};
