# Demo of Generic document windows, DC, and Font usage
# by Dave Brennan (brennan@hal.com)
# usage examples:
# >>> from fontdemo import *
# >>> d = FontDemo('Hello, Python')
# >>> f1 = { 'name':'Arial', 'height':36, 'weight':win32con.FW_BOLD}
# >>> d.SetFont(f1)
# >>> f2 = {'name':'Courier New', 'height':24, 'italic':1}
# >>> d.SetFont (f2)
