    13 Co-ordinate System</title><shortdesc>The co-ordinate origin of a window is its top left corner. Positive

    14 co-ordinate values indicate positions to the right and down from the origin.

    15 Negative values are also valid, and indicate co-ordinates outside the window's

    16 extent. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

    17 <p> <b>Variant</b>: Both (ScreenPlay and non-ScreenPlay). <b>Target

    18 audience</b>: Application developers. </p>

    19 <p>Each window has a position, which is the position of its origin relative

    20 to its parent’s origin. If its parent is a window group, then its position

    21 is effectively relative to the top left corner of the screen or display device,

    22 because window groups do not have a size. </p>
