property operation

This property returns the kind of operation that we can do as we drag and drop. The value of this property can be:

• appUtils.TRANSFER_OPERATION_NONE
• appUtils.TRANSFER_OPERATION_MOVE
• appUtils.TRANSFER_OPERATION_COPY
• appUtils.TRANSFER_OPERATION_LINK
• appUtils.TRANSFER_OPERATION_BLOCK

// when an item is dragged over this box, we set the drag operation
<box on:dragOver="onDragOver();"/>

function onDragOver()
{
    var eventObj = shell.currentEvent;
    if (eventObj)
    {
        eventObj.operation = appUtils.TRANSFER_OPERATION_COPY;
    }
}
