I would like to create a custom Raphael element, with custom properties and functions. This object must also contain predefined Raphael objects. For example, I would have a node class, that would contain a circle with text and some other elements inside it. The problem is to add this new object to a set. These demands are needed because non-Raphael objects cannot be added to sets. As a result, custom objects that can contain Raphael objects cannot be used. The code would look like this:
var Node = function (paper) {
// Coordinates & Dimensions
this.x = 0,
this.y = 0,
this.radius = 0,
this.draw = function () {
this.entireSet = paper.set();
var circle = paper.circle(this.x, this.y, this.radius);
this.circleObj = circle;
this.entireSet.push(circle);
var text = paper.text(this.x, this.y, this.text);
this.entireSet.push(text);
}
// other functions
}
var NodeList = function(paper){
this.nodes = paper.set(),
this.populateList = function(){
// in order to add a node to the set
// the object must be of type Raphael object
// otherwise the set will have no elements
this.nodes.push(// new node)
}
this.nextNode = function(){
// ...
}
this.previousNode = function(){
// ...
}
}
