    fill: 'red',
    width: 300,

</script>

Supported Events and Objects:

Events

canvas:

// Double click
canvas.on('mouse:dblclick', function (options) {
});

// Mouse right button down
canvas.on('mouse:down', function (options) {
  if (options.e.which === 3) {
    console.log('Canvas right mouse down.');
  }
});

object:

// Double click
rect.on('object:dblclick', function (options) {
});

// Mouse right button down
rect.on('mousedown', function (options) {
  if (options.e.which === 3) {
    console.log('Object right mouse down.');

Event for objects inside a group

By default, any object inside a group will not recieve any event individually. Add below line of code if you want group objects recieve events individually.

canvas.fireEventForObjectInsideGroup = true;
