Sam,
Yes, some thing like that would be great. It would also be nice to
handle arrays of locations without the 'px' so it is easy to do math on
them.
// place a circle at the center of some container
$("#container").drawShape("circle", { origin: "centre", radius: 30})
// draw a circle
$("#container").drawShape("circle", { origin: [5,8], radius: 30})
// draw multiple circles and style them all the same
$("#container").drawShape("circle", { origin: [[5,8],[30,45],...],
radius: 30, style: {color: "red", opacity: .5, border-color: #900,
border-style: "solid"}})
// draw a polyline
$("#container").drawShape("line" { path: [[5,8],[30,45],...], style:
{color: "red", line-style: "dashed", lineWidth: 2}}).bind("mouseover",
function(e){alert("I'm a line");});
I also think there is something to be said for creating shape objects like:
var redcircle = {
id: "circle01",
type: "circle",
x: 5,
y: 8,
radius: 30,
style: {color: #f00;},
};
var bluecircle = {
id: "circle02",
type: "circle",
x: 5,
y: 8,
radius: 10,
style: {color: #00f;},
};
var shapes = [];
shapes.push(redcircle);
shapes.push(bluecircle);
// add to circles, then hide the larger
$("#container").addShape(shapes);
$("#circle01").hide();
or
// add two circles (nested), then hide both of them
$("#container").addShape(redcircle);
$("#circle01").addShape(bluecircle);
$("#circle01").hide();
Anyway you get the idea.
