can-set-size-constraint?

Called before the editor's maximum or minimum height or width is changed. If the return value is #f, then the change will be aborted.

(This callback method is provided because setting an editor's maxmimum width may cause lines to be re-flowed with soft carriage returns.)

See also on-set-size-constraint, after-set-size-constraint, and on-edit-sequence.
