pce_catch_errors/2

pce_catch_errors(+Id, +Goal)

Handle XPCE errors raised while Goal is called. Id is either the id of an error object or a chain of such ids. If one of the listed errors occurs the goal silently fails and @pce<-last_error holds the id of the trapped error. Any other error encountered while Goal runs is handled by XPCE's normal error-handling mechanism.

Exceptions are repairable errors. Exception handlers may be installed in @pce<-exception_handlers.
