Description

The values x-adjust and y-adjust of the slots are used by layouts to decide what to do when a pane is smaller than the space in which it is being laid out. Typically the values will be a keyword or a list of the form (keyword n) where n is an integer. These values of adjust are interpreted as by pane-adjusted-position.

:top is the default for y-adjust and :left is the default for x-adjust.

Examples

Note: column-layout is a subclass of x-y-adjustable-layout.

                               (make-instance
