+</span> * A Surface is an interface to render methods inside a draw {@link Ext.draw.Component}.
* A Surface contains methods to render sprites, get bounding boxes of sprites, add
* sprites to the canvas, initialize other graphic components, etc. One of the most used
* methods for this class is the `add` method, to add Sprites to the surface.
* The configuration object passed in the `add` method is the same as described in the {@link Ext.draw.Sprite}
* class documentation.
*
- * ### Listeners
+ * # Listeners
*
* You can also add event listeners to the surface using the `Observable` listener syntax. Supported events are:
*
*
* For example:
*
- drawComponent.surface.on({
- 'mousemove': function() {
- console.log('moving the mouse over the surface');
- }
- });
+ * drawComponent.surface.on({
+ * 'mousemove': function() {
+ * console.log('moving the mouse over the surface');
+ * }
+ * });
+ *
+ * # Example
+ *
+ * var drawComponent = Ext.create('Ext.draw.Component', {
+ * width: 800,
+ * height: 600,
+ * renderTo: document.body
+ * }), surface = drawComponent.surface;
+ *
+ * surface.add([{
+ * type: 'circle',
+ * radius: 10,
+ * fill: '#f00',
+ * x: 10,
+ * y: 10,
+ * group: 'circles'
+ * }, {
+ * type: 'circle',
+ * radius: 10,
+ * fill: '#0f0',
+ * x: 50,
+ * y: 50,
+ * group: 'circles'
+ * }, {
+ * type: 'circle',
+ * radius: 10,
+ * fill: '#00f',
+ * x: 100,
+ * y: 100,
+ * group: 'circles'
+ * }, {
+ * type: 'rect',
+ * width: 20,
+ * height: 20,
+ * fill: '#f00',
+ * x: 10,
+ * y: 10,
+ * group: 'rectangles'
+ * }, {
+ * type: 'rect',
+ * width: 20,
+ * height: 20,
+ * fill: '#0f0',
+ * x: 50,
+ * y: 50,
+ * group: 'rectangles'
+ * }, {
+ * type: 'rect',
+ * width: 20,
+ * height: 20,
+ * fill: '#00f',
+ * x: 100,
+ * y: 100,
+ * group: 'rectangles'
+ * }]);
+ *
+ * // Get references to my groups
+ * circles = surface.getGroup('circles');
+ * rectangles = surface.getGroup('rectangles');
+ *
+ * // Animate the circles down
+ * circles.animate({
+ * duration: 1000,
+ * to: {
+ * translate: {
+ * y: 200
+ * }
+ * }
+ * });
+ *
+ * // Animate the rectangles across
+ * rectangles.animate({
+ * duration: 1000,
+ * to: {
+ * translate: {
+ * x: 200

+ * }
