Description

The function contain creates and displays a container for the CAPI element element. contain returns element as its result.

contain is provided as a convenient way of testing CAPI functionality and is useful mainly during interactive development. Many of the CAPI examples use it.

The container is created using make-container, which can make containers for any of the following classes:

In the case of a cl:list, the CAPI tries to see what sort of objects they are and makes an appropriate container. For instance, if they were all simple-panes it would put them into a column-layout.

interface-args, after removing the arguments screen and process, are passed to make-container as the initargs to the interface. title is used as the title of the container.

as-dialog can be nil, t or :no-escape-button. The default value of as-dialog is nil, which means display the interface as an ordinary window using display. When as-dialog is true it displays using display-dialog. When as-dialog is t, contain adds to the interface an escape button which invokes abort-dialog, to ensure that the user does not get stuck with a dialog that cannot be dismissed. When as-dialog is :no-escape-button, it does not add the escape button. Any value of as-dialog has the same effect as t.

The values of the arguments screen and process are passed to display when displaying the container.

Examples
(capi:contain (make-instance 'capi:text-input-pane))
(capi:contain (make-instance
               'capi:column-layout
               :description `("Title:"
                              ,(make-instance
                                'capi:text-input-pane))))
(capi:contain (make-instance 'capi:menu-item)
