# This example application shows how interface focus works.
#
# If you have cloned this repository from GitHub, you can run this example:
#
#     ./examples/focus_app.rb
#
#
# First, we set up the interfaces, noting that 'copper' should have focus when
# the application starts. Also note that 'status' should not show a cursor.
#
# The focus order is: copper, aluminium, boron, dubnium, status.
#
# Use 'space' to change focus, 'q' to exit.
