bottom-attachment

Arguments: standard-object

Returns or sets with setf the value of the bottom-attachment property of the argument. This property determines which edge of the parent window the bottom edge the object will follow whenever the parent window gets resized. See also top-attachment, left-attachment, and right-attachment.

The possible values and their effects are:

A control that drops a list of choices when clicked (namely a combo-box or dropping-outline control) always has the same height when not showing its dropping list, and so bottom-attachment for these controls applies to the bottom of the dropped list of choices instead. To keep the dropping list the same height as the user resizes the parent window, bottom-attachment should be the same as the top-attachment. (When both attachments are :scale, a control normally resizes proportionally as its parent window is resized; a dropping list is an exception since it is typically more desirable for the list to continue to show the same number of items than it is to prevent it from overlapping other controls.)

See also top-attachment, left-attachment, right-attachment, track-limits and resize-window.
