Fabric.js - 在所选对象下移动对象

Question

I have 2 objects (images) in my canvas.

fc.item(0) is a smaller image in the middle of the canvas. fc.item(1) is a large image, "frame". The user can't move it. When the user's trying to move the fc.item(1) , I wanna move the fc.item(0) , as if the user's moved on the fc.item(1) .

Any idea, how can I do this? I tried to use the fc.item(0).fire("object:moving") , but this didn't work well.

If you want to make top object unselectable just set its "selectable" to false .

fc.item(1).selectable = false;

If you also want to propagate events to the bottom object (essentially "ignoring" top one), set top one's "evented" property to false .

fc.item(1).evented = false;
