Events

Move and resize event listeners can be added to each grid-item, so that the parent Vue can be notified when a grid element is being moved or resized. Moved and resized event listeners can be added, if the only notification needed is when an item is finished moving or resizing.

Working example here

    <grid-layout
            :layout="layout"
            :col-num="12"

            :is-resizable="true"
            :vertical-compact="true"
            :margin="[10, 10]"
            :use-css-transforms="true"
            @layout-updated="layoutUpdatedEvent"
    >

        <grid-item v-for="item in layout"

  • layoutUpdatedEvent

    Every time an item is being moved and changes position

    },
  • resizeEvent

    Resize event

    Every time an item is being resized and changes size

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

    },
  • movedEvent

    Moved event

  • resizedEvent

    Resized event

    Every time an item is finished being resized and changes size

    /**
     *

     * @param newW new width in grid columns
     * @param newHPx new height in pixels
     * @param newWPx new width in pixels
     * 
     */
    resizedEvent: function(i, newH, newW, newHPx, newWPx){
