I'm working on a enyo application. I want to draw on a svg. This is my code so far:
enyo.kind({
name:"draw",
kind:enyo.Control,
tag:"svg",
attributes:{
xmlns:"http://www.w3.org/2000/svg",
version:"1.1"
},
classes:"drawSvg",
published:{
drawSize:5,
selectedColor:"333333",
paths:0
},
handlers:{
ondown:"onDownHandler",
onmove:"onMoveHandler"
},
create:function(){
this.inherited(arguments);
this.render();
},
rendered:function(){
this.inherited(arguments);
},
onDownHandler:function(sender,target){
this.iPaths++;
var p = this.getPositionInSvg(target);
var path = document.createElementNS("http://www.w3.org/2000/svg", "path");
path.setAttribute('class', 'drawpath'+ this.iPaths);
path.setAttribute('fill', 'none');
path.setAttribute('stroke', '#'+this.getSelectedColor());
path.setAttribute('stroke-width', this.getDrawSize());
path.setAttribute('d', "M " + p.x + "," + p.y);
$(this.hasNode()).append(path);
},
onMoveHandler:function(sender,target){
var p = this.getPositionInSvg(target);
$('. drawpath'+ this.iPaths).attr("d", $('. drawpath'+ this.iPaths).attr("d") + " L "+ p.x+","+ p.y);
},
getPositionInSvg:function(target){
var pos = new Object();
pos.x = ((target.pageX - this.hasNode().offsetLeft) / window.settings.SCALE) + 0.5>>0;
pos.y = ((target.pageY - $(this.hasNode()).offset().top) / window.settings.SCALE) + 0.5>>0;
return pos;
}
});
When I look at the generated HTML code in firebug. This is the code:

I think the generated code looks good. But I don't see anything in the svg. Nothing is rendered and the svg is empty.
I verified with the nightly Enyo that I can do a very simple SVG test.

Declaring
{name: "svg", tag: "svg", attributes: {xmlns: "http://www.w3.org/2000/svg", version: "1.1"}}
in the app kind works just fine, I didn't try it as a standalone kind.
