above-parent

Arguments: outline-item

Returns whether an outline-item will be drawn above its parent item rather than in the normal location below the parent. The value may be set at creation time by passing the above-parent initarg, or any time later by calling (setf above-parent). The default value is nil.

Placing some outline-items above their parent and others below could be used to distinguish the two groups of items in some application-specific way.

An outline-item will be placed above its parent item only when its above-parent property is true and the outline widget's handle-above-parent property is also true.
