set-wordbreak-func

Sets the word-breaking function for the buffer. For information about the arguments to the word-breaking function, see find-wordbreak.

Since the wordbreak function will be called when line breaks are being determined (in a buffer that has a maximum width), there is a constrained set of wx:media-edit% methods that the wordbreak function is allowed to invoke. It cannot invoke a member function that uses information about graphic locations or lines (which are identified in this manual with `` The result is only valid when the buffer is viewed (see Basic Organization).''), but it can still invoke member functions that work with snips and item positions.

The standard wordbreaking function uses the buffer's wx:media-wordbreak-map% object to determine which characters break a word. See also wx:media-wordbreak-map% and set-wordbreak-map.
