Animation when adding items to qgraphicsLayout

[wagmare]

Hi friends,

In QgraphicsWidget im adding new items (QGraphicsLayoutItem) using Drag/drop on the QGraphicsWidget and using QGraphicsLinearLayout. If the user wants to move or create the item between the items already present in the layout , i have to animate the movement when the item is inserted between two items like top item moving upwards and the bottom item moving downwards with some time gap.

there is one proposal in this link , but i dont know how to implement in this fashion
