[REBOL] Re: [View // Face] Event redirection within face hierachies
From: reblist::codeconscious::com at: 20-Jun-2004 13:44
I don't think you can redirect/modify a value having the Event! type, but I
also don't think you need to for this application. I'd hazzard a guess that
you can do the things you described right now, but can not say whether the
technology involved or your design is suitable/reliable enough for such a
high saftey related item as you have described (esp. if the pilot needs to
use the application in-flight).
There is a demo draw program ("paint" ?) by frank that shows how lines can
be dynamically drawn. You might be able to make a single face that
incorporates the drawing functionality you need.
Check out the Detect function of the Feel Object in View. It has the ability
to receive events, handle them, pass them through and/or drop them.
Also check out the Insert-event-func function which has the same properties
as Detect but sits at the application level.
See ( do http://www.codeconscious.com/rebsite/view-notes.r ; "global level
events").
Look into iterated face (or what I've called "calculated panes" in that
rebsite link above). These may provide a different sort of flexibility for
your application, don't assume all the iterations have to appear linearly.
Below is a compressed script that demo's a dial based on an iterated face.
Cheers,
Brett.
