# This implements a virtual device for creating user
|
|
# interfaces on Pythonista (a Python 3 system for
|
|
# iOS).
|
|
#
|
|
# The layout system as designed by Arland uses a grid
|
|
# system (defaulting to 10x10). We hope to offer a
|
|
# stack based (ala SwiftUI) option in the future.
|
|
#
|
|
# It's intended that we will port this to other systems
|
|
# as well. On iOS, Pyto is another good target (though
|
|
# we have less experience with it), and there are a
|
|
# number of options on desktop OSes.
