object-string

Arguments: object

Returns a string derived from an arbitrary object. When a command that acts on a string (such as apropos or find-in-files) is invoked in the Allegro development environment, the default selected-string method finds a string to apply the command to by calling object-string on the selected-object of the selected window. Object-string may return nil if a string cannot be derived in some reasonable way from the object. Object-string is bypassed if there is a more specific selected-string method for a particular command and selected window; these more specific methods sometimes exist when it is not sufficient to funnel through the general selected-object in order to derive a selected-string for the window.
