Custom shape of bounding rect

[Kamalpreet]

Hi

I am drawing a line using mouse clicks. The line is drawn using paint function as:

painter->drawLine(start_p, end_p);

painter->drawLine(start_p, end_p);

To copy to clipboard, switch view to plain text mode 

The bounding rect of line is defined as:

QRectF Line::boundingRect() const
{
    // bounding rectangle for line
    return QRectF(start_p, end_p).normalized();
}

QRectF Line::boundingRect() const
{
    // bounding rectangle for line
    return QRectF(start_p, end_p).normalized();
}

To copy to clipboard, switch view to plain text mode

This shows the line painted. I get the bounding rect for this as shown:

I want to have the bounding rect according to the shape of the item, something like:
