EaselJS拖拽：获取抓取位置

Question

I'd like to drag-drop a container element with easeljs. By default event.stageX/stageY refers to the center of the shape or container. That means that large elements are centered at mouse position, doesn't matter, whether I grab them at the top-left or bottom-right corner.

I'd like to have the element bound to the exact mouse position.

Sorry for my bad English, it's not my mother tongue.

Maybe it's too late but hope this helps.

container.on('mousedown', function(e){
        var posX = e.stageX;
        var posY = e.stageY;
        this.offset = {x: this.x - posX, y: this.y - posY};
}
container.on('pressmove', function(e){
    var posX = e.stageX;
    var posY = e.stageY;
    this.x = posX + this.offset.x;
    this.y = posY + this.offset.y;
}
