# 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)

# font is a dictionary in which the following elements matter:
# (the best matching font to supplied parameters is returned)
#   name		string name of the font as known by Windows
#   size		point size of font in logical units
#   weight		weight of font (win32con.FW_NORMAL, win32con.FW_BOLD)
#   italic		boolean; true if set to anything but None
#   underline	boolean; true if set to anything but None
