[REBOL] Viewing two or more copies of the same layout
From: robbie_armour::hotmail::com at: 10-Feb-2004 3:59
Firstly, hello from a newbie who's been captivated by Rebol since first
sight. It's a brilliant concept brilliantly done.
Apologies if this has been covered before, but I'm trying to set up an
application, part of which involves editing patient records. I think the
user should be able to have two or more patient records open at once, but I
cannot get Rebol to display a layout defined within an object more than once
(I need the object context to avoid having one set of global variables
trying to hold two records' data). No permutations of copy or copy/deep
seem to do it, and if I attempt eg obj2/lyt: make obj1/lyt  I get "face in
more than one pane" errors.
Ironically if I define the layout twice globally it works fine, and the two
layouts are different and there are no shared faces.
A bit more detail: I have an object defined eg:
patient-record: context [
lyt: layout [
btn-enter "Save" [; save record to database for this id]
populate: func [i [integer!]] [
; set f1/text = to name from database where id = i
The user selects a name from a text-list of patients, and clicks the "edit"
button, and the associated code does:
p: make patient-record [self/populate 1]
If the program later does:
p: make patient-record [self/populate 2]
the new layout does not get shown at all.
Thanks for your help (and for Rebol!), Robbie the Rebol
