Hi Alex,
I am Using Pyglet to browse (interactively) the contents of an Object
database such as ZODB. Since it is impracticable to send you the
database, I am sending you a script that, shows the problem, which
seems to be related to assigning long strings to text objects.
I understand that this problem may not necessarily be minimizable,
since pyglet is not meant to be a text editor.
BTW i am running Ubuntu Feisty
here is the code:
from pyglet import font
from pyglet import clock
from pyglet import window
from pyglet import image
from pyglet.gl import *
from pyglet.window import mouse
from pyglet.window import event
from pyglet.window import key
import random
win = window.Window(resizable=True)
ft = font.load('Arial', 22)
T = font.Text(ft,"",valign=font.Text.TOP,y=win.height-40,width =
win.width)
def change_text():
longstring = ','.join([str(random.random()) for i in
xrange(10000)])
T.text = longstring
def mainLoop():
"""
Interface mainloop
"""
#clock.set_fps_limit(30)
while not win.has_exit:
win.dispatch_events()
glClear(GL_COLOR_BUFFER_BIT)
#win.clear()
change_text()
T.draw()
win.flip()
glEnable(GL_BLEND)
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
mainLoop()
