# --------------------------------------------------------------------
#
# NAME: wxtest.py
#
# PURPOSE: Test interaction when combining wxPython and PyGist
#
# NOTES:
# Dave Grote (LBNL) was able to develop a GUI with wxWindows and PyGist
# because wxWindows has an idle event. Because in wxPython, the idle
# event is only called once each time the window goes idle, Dave came
# up with a workaround available in wxPython (to request that another
# idle event be sent). His solution is illustrated below.
#
# While we can get the GUI and the Gist window to each respond to
# events, the solution is not perfect. If the GUI window covers the
# Gist window, the Gist window is not redrawn when exposed until the
# mouse enters GUI window.
#
# CHANGES:
# 03/06/03 llc Originated.
