6.7 Changing layouts and panes within a layout

To change to another layout, use (setf pane-layout):

(setf layout 

      (capi:contain 

       (make-instance 'row-layout 

                      :description 

                      (list (make-instance 'title-pane :text "One") 

                            (make-instance 'title-pane :text "Two"))

                      :visible-min-height 100)))

(apply-in-pane-process

 layout #'(setf pane-layout)

 (make-instance 'column-layout 

                :description 

                (list (make-instance 'title-pane :text "Three") 

                      (make-instance 'title-pane :text "Four"))) 

 (element-interface layout))

To change the panes within a layout, use (setf layout-description):

(setf layout 

      (capi:contain 

       (make-instance 'row-layout 

                      :description 

                      (list (make-instance 'title-pane :text "One") 

                            (make-instance 'title-pane :text "Two"))

                      :visible-min-height 100)))

(apply-in-pane-process

 layout #'(setf layout-description)

 (list (make-instance 'title-pane :text "Three") 

       (make-instance 'title-pane :text "Four")

       (make-instance 'title-pane :text "Five"))

 layout)

Note: A CAPI layout must not reuse panes that are already displayed in another layout.
