[REBOL] Re: Adding an action to an existing event

The easy part is to say, make a clone the object (so you do not affect normal fields). Engage is just a function. So if it makes sense you could save the old one and write a new one that will do what you want, but call the old one (only if a condition is met perhaps) - in a way chaining them. Maybe this will work for you: stylize/master [ special-field: field with [ feel: make ctx-text/edit [ engage: func [face act event][ either 'up = act [ print "MOUSE UP" ][ ctx-text/edit/engage face act event ] ] ] ] ] view layout [special-field] Brett.
