Using Hammerjs events within the Kineticjs Canvas

Question

I am trying to use Hammer.js events within the Kinetic.js canvas and can't seem to get it working. I have tried both of the following:

var background = new Kinetic.Rect({
        x: 0,
        y: 0,
        width: image.getWidth(),
        height: image.getHeight(),
        id: "background",
        fill: 'rgba(159, 255, 200, 0.0)',
    });
    pointLayer.add(background);
    pointLayer.draw();

background.hammer().on('tap', function (e) {
        console.log("Background tapped");
});

OR

Hammer(background).on('tap', function (e) {
        console.log("Background tapped");
});

When using the first method, I get an error "has no method 'hammer'". The other I get no messages. Is it possible to use Hammer.js within the Kinetic.js canvas?

Answer 1

It is posibble. But you can not listen kineticjs objects with hammer. You can listen documet elemets. For example canvas of layer or whole stage element.

var transformer = Hammer(stage.getContainer())  //kineticjs stage
transformer.on("transformstart", function(){
   // your code
});

Update:

Currently you can use KineticJS nodes and HammerJS events. (little patch need) First look at demo listed here: https://github.com/lavrton/KineticJS-HammerJS-test
