| Allegro CL version 9.0 Unrevised from 8.2 to 9.0. 8.2 version |
Arguments: standard-object
Returns or sets with setf the value of the top-attachment property of the argument. The top-attachment property of an object determines which edge of the parent window the top edge of the object will follow whenever the parent window is resized. See also bottom-attachment, left-attachment, and right-attachment.
The possible values and their effects are:
:bottom
: object maintains a constant distance
between its upper edge and the lower edge of its parent window
whenever that window is resized.
:scale
: object maintains the same ratio of the
distances from the top and bottom sides of its parent window whenever
that window is resized. I.e., if the top edge was halfway between
the top and bottom sides of the dialog before resizing, then it is
still halfway between them after resizing.
:top
: object maintains a constant distance between
its upper edge and the upper edge of its parent window whenever that
window is resized.
See also left-attachment, right-attachment, bottom-attachment, track-limits and resize-window.
