Description

The background and foreground colors are colors specified using the graphics ports color system, and the font must be a generic font. The value for visible-border can be any of the following:

nil

Has no border.

t

Has a border.

:default

Use the default for the window type.

Any simple pane can be made to scroll by specifying t to :horizontal-scroll or :vertical-scroll . By default these values are nil , but some subclasses of simple-pane default them to t where appropriate (for instance editor-panes always default to having a vertical scroll-bar). The height and width of a scrollable simple pane can be specified by the initargs :scroll-height and :scroll-width , which have the same meaning as :internal-min-height and :internal-min-width . See the LispWorks CAPI User Guide for more information about height and width initargs.

In order to display a simple pane, it needs to be contained within an interface. The two convenience functions make-container and contain are provided to create an interface with enough support for that pane. The function make-container just returns a container for an element, and the function contain displays an interface created for the pane using make-container .

Examples

(capi:contain (make-instance 'capi:output-pane

                  :background :red

                  :scroll-width 300

                  :horizontal-scroll t))

(capi:contain (make-instance 'capi:editor-pane

                              :visible-border t))
