Initargs

`:ratios`	The size ratios between the layout's children.

`:uniform-size-p`	If `t`, each child in the column has the same height.

Accessors

layout-ratios

Description

The class column-layout lays its children out in a column. It inherits the behavior from grid-layout. The description is a list of the layout's children, and the layout also translates the initargs ratios, adjust, gap and uniform-size-p into the equivalent grid-layout initargs y-ratios, x-adjust, y-gap and y-uniform-size-p.

description may also contain the keywords :divider and :separator which create a divider or separator as a child of the column-layout. The user can move a divider, but cannot move a separator.

When specifying :ratios in a row with :divider or :separator, you should use nil to specify that the divider or separator is given its minimum size, as in the example below.

               'capi:column-layout

                "Title"
                (make-instance 'capi:list-panel
