[REBOL] listen to events only for a specific window?

From: arolls::bigpond::net::au at: 11-Jul-2001 17:25

How can I have two windows open, but listen for events on only one of them? eg. If you click on the button, an error is generated and the error window pops open. But! You can still click on the button! The first window is still receiving events. I want to stop/pause that until user makes a decision in the error window. lay: layout [ button [lafd] ; generate error ] ; If an error happens in the VID code, I am going to catch it. first-time?: yes while [ error? err: try [ either first-time? [view center-face lay][wait none] ] ][ if error? err [err: disarm err] first-time?: no view/new layout [ origin 5x5 h3 "Program Error" across button "continue" [unview] button "quit" [unview/all halt] return area mold err ] ; this effectively continues from here - it shouldn't. ; I want to listen only to the error window ; until "continue" is pressed. ;probe wait/all [] ]
