    <grid-layout
            :layout="layout"

# GridItem

# moveEvent

# resizeEvent

调整大小时的事件

    resizeEvent: function(i, newH, newW, newHPx, newWPx){

    },

# movedEvent

移动后的事件

    movedEvent: function(i, newX, newY){

# resizedEvent

调整大小后的事件

    /**
     * 
     * @param i the item id/index

     * @param newWPx new width in pixels
     * 
     */
    resizedEvent: function(i, newH, newW, newHPx, newWPx){
        console.log("RESIZED i=" + i + ", H=" + newH + ", W=" + newW + ", H(px)=" + newHPx + ", W(px)=" + newWPx);
