Well ... I wrote this, but surely is not the right way to do it,
because I started working with python+pygame 2-3 weeks ago:
# Loop to get keystrokes and insert them into the string
done = 0
mystring = ""
while not done:
clock.tick(20)
text = font.render( str(mystring) + "_", 1, (180,180,0))
newsize = text.get_rect()
screen.fill( bg, [tx+textsize.w, ty, w-textsize.w-32, newsize.h+2] )
screen.blit( text, (tx+textsize.w, ty) )
pygame.display.flip()
for event in pygame.event.get():
if event.type == KEYDOWN:
key = event.key
if key == K_ESCAPE: done = 1
# Delete key
elif key == K_BACKSPACE and mystring != []:
mystring = mystring[:-1]
# Enter: check if the string is valid
elif key == K_RETURN and mystring != [] :
value, done = mystring, 1
# Any other key: numbers, letters...
else:
the_key = event.unicode
ascii = ""
if the_key.isalnum() \
or the_key in ( '.', '_', '-', ' ' ):
ascii = the_key.encode('latin1')
if len(mystring) < string_limit and ascii != "":
mystring = mystring[:] + ascii
Hope that helps.
