scrollbars

Arguments: standard-object

Returns the value of the scrollbars property of the argument.

This property is unrelated to the scrollbar controls (horizontal-scroll-bar and vertical-scroll-bar) but instead refers to system-provided scrollbars for certain windows and controls. The value can be one of:

For windows other than controls, the page-height and page-width properties control the range of the scrollbars; for controls, the range is determined by the control's contents.

A combo-box cannot have a horizontal scrollbar, and so :vertical and nil are the only choices that appear in the inspector for this property, though t will still work to enable the vertical scrollbar.

A single-item-list or multi-item-list may have a horizontal scrollbar, but it will only appear if the multi-column-p property is true; this is a limitation in Windows. If a horizontal scrollbar is needed on an item-list that does not use multiple columns, an outline control could be used instead, using only top-level items in the range and turning off the draw-icons property to simulate an item-list.

This function is not setf'able. The scrollbars of a window or dialog-item must be established with the :scrollbars initarg when it is created, or using the inspector when designing a window or widget on a form.
