"Dead zone" around MouseArea when dragging?

[gabzuka]

Hi Guys,

I'm trying to drag a Rectangle but I notice that when I press down and start moving the cursor the rectangle doesn't start dragging until my mouse is outside the MouseArea. Is there a way of controlling this? Ideally I would like to start dragging as soon as the mouse moves, not until it leaves the mouse area.

Here is my code:
@import QtQuick 2.0

Item
{
id: key
width: key_rect.width
height: key_rect.height

MouseArea
{
    id: drag_area
    width: 50
    height: 14
    drag.target : key
    drag.axis : Drag.XAxis

    Rectangle
    {
        id:key_rect
        width: 14
        height: 14
        color: "#FFFFFF"
    }
}

}@
