15.6 Defining the callbacks
display-pane-selection
, which displays, in a dialog, the current selection of any pane.(defun display-pane-selection (reader data interface) (declare (ignore data)) (capi:display-message "~S: ~S selected" (capi:capi-object-name (funcall reader interface)) (capi:choice-selected-items (funcall reader interface))))The following two functions call
display-pane-selection
, passing the reader of a pane as an argument. These functions are specified as the callbacks for the two menu items.(defun display-graph-selection (&rest args) (apply 'display-pane-selection 'graph-reader args))As with the other callback functions, specifying the callbacks in this way allows for easy extension of the example.(defun display-list-selection (&rest args) (apply 'display-pane-selection 'list-reader args))
