13.4.29 Controlling slider display

The new initarg :tick-frequency allows you to specify whether a capi:slider has tick marks, and how the tick marks are spaced. In LispWorks 6.0 and earlier versions, slider tick marks do not appear on all platforms, and there is no control over them in CAPI.

On Microsoft Windows and GTK+, the new initarg :print-function and accessor capi:slider-print-function allow you to control how the slider displays its current value.
