column-label-orientation

Arguments: lamp

A property of the lamp widget. This generic function returns whether the label strings that are above or below the columns of images in a lamp widget are drawn vertically of horizontally. The value may be one of the keyword symbols :vertical or :horizontal. The value may be specified at creation time with the column-label-orientation initarg, or anytime later by calling (setf column-label-orientation). This value is used only when the value property of the lamp widget is an array.

Generally :horizontal is a good choice when the strings are short enough (such as a single letter) to fit horizontally above or below each column. Otherwise :vertical would be needed, though :vertical amkes the labels a bit harder to read.
