This function calculates the offset required by the adjust keyword so that the pane pane is placed correctly within the available space in its parent layout. It is called by all of the layouts that inherit from x-y-adjustable-layout to interpret the values of x-adjust and y-adjust .
Typically the value of
will be a keyword or a list of the form
where n is an integer. These values of
are interpreted as by pane-adjusted-position.
However, new methods can accept alternative values for adjust where required and can also add extra keywords. For example, grid-layout allows adjust to be a list of adjust values, and then passes the offset into this list as an additional keyword.
