[REBOL [ Comment: { Hi Marc, Some other ways to do the hiding stuff and a bit explanation. Why does changing /show? not work in your demo? Changing face-facets is deferred until the face is redrawn. that happens when you move the mouse over the button, or when you call 'show on the face. You discovered the post-view-processing trick based on rate. Another way to do it is shown below. system/view/screen-face/pane holds all windows, if we have exactly one after view/new there is only ours, so we start the event-loop ('view makes a similar decision). But instead of hiding unused buttons, i prefer to gray it. see the "inactive" -toggle. (for effects try "rebol/demos/effect-lab" from the rebtop) } Author: "Volker" ] ;print "console.." ; for debugging immediate.. lay: layout [ text "the demo-button" tx: button "click me" [alert "click"] text "do stuff with it" across check [either face/data [show tx] [hide tx]] text "show" return check true [either face/data [ tx/pane: none ] [ tx/pane: make-face/size/spec 'image tx/size [ effect: [merge blur cross] ] ] show tx ] text "active" below button "quit" #"^q" [quit] ] view/new center-face lay wait 0.01 ;process initial events, window open etc. hide tx ;now this works if 1 = length? system/view/screen-face/pane [do-events] ]
