[gcompris-devel] help! canvas refresh

[Bruno Coudoin]

Here is a working code:

  def show_bang(self, a):
    print "show_bang a="+str(a)
    if a==1:
      self.bang_item.set(x=150,y=50)
    elif a==2:
      self.bang_item.set(x=550,y=50)
    elif a==3:
      self.bang_item.set(x=150,y=250)
    else :
      self.bang_item.set(x=550,y=250)
   
           
  def repeat(self):
    print("Gcompris_melody repeat.")
    #self.bang_item.show()
    timer = 0
    for a in self.solution[:]:
      gcompris.sound.play_ogg("melody/son"+str(self.a))
      self.show_bang_timer = gtk.timeout_add(timer, self.show_bang, a)
      timer = timer + 1000


What happens is that sound.play_ogg is multithreaded and queued. You get
the hand always after the call, not after the sound is played.
Here, we loop at full speed and I arm the timer with a second interval.

Never use timer.sleep in gcompris or you sleep the whole gcompris
process including the main event loop. The result is never what you
want.

For the cursor, you can create one but the process is not so easy. Look
at src/gcompris/cursor.h to add your own.

Bruno.
