[open] Limit the time to start input text

  actually,
  I convinced the research-student that she doesn't need the reminder,
  but I have another problem -

  When I (the program) wait for response to the sequence,
  I couldn't actually record it - the first letter is missed,
  and the subject need to rewrite it in second he sees it wasn't writen.

  yes I know - it is saved on the logger, but
  I want the subject won't be confused with what he typed or not.
  If it was keyboard response I'd let the duration be "0",
  but I couldn't do this in the case of input_text_form...

  thank's a lot for reading all these pettiness,

  Hi Shilo,

  Do I understand correctly that you use a regular form_text_input, but that this does not register the first typed character? If so, could you post the script of your experiment, or a clearer description of what you're doing precisely?

  Cheers!

  actually,
  I found a script of Sebastian that was mantioned here that suited me.

  http://forum.cogsci.nl/index.php?p=/discussion/31/solved-multi-character-keyboard-response-or-simultaneous-sketchpad-and-text_input/p1

  Now I have another problem. (the oposite one)

  my sequence its:

  fixation

  word (sketchpad with a duration set to 7000)

  word waiting (sketchpad with a duration set to 0)

  the_script

  logger

  I want him to start record the letters only while the second
  scatchpad is shown. but the programm record the letter that was typed
  while the first one was shown.

                      Thanks a lot,
                              Shilo

  Not sure which script you used, but I assume it's the simpler one (not PyGame specific). I've added two lines in there to call the get_key until all previous input is gone. Now the script should only collect the stuff typed while the second sketchpad is visible.

  # import the stuff we need
  from openexp.canvas import canvas
  from openexp.keyboard import keyboard
  
  # create the instances we need
  my_canvas = canvas(self.experiment)
  my_keyboard = keyboard(self.experiment)
  
  # catch all early responses
  while my_keyboard.get_key(timeout=1)[0] != None:
      pass
  
  # empty string to store the response
  resp = ""
  
  # loop until 'break' is called
  while True:
      # Get a keyboard response
      key, time = my_keyboard.get_key()
      # If return is pressed the loop should be exited
      if key == "return":
          break           
      # Handle backspace by removing the last character
      if key == "backspace":
          resp = resp[:-1]    
      else:
          # add character to response
          resp += key
      # Copy the canvas from a sketchpad called 'my_sketchpad' and
      # overlay the response
      my_canvas.copy(self.experiment.items["my_sketchpad"].canvas)
      my_canvas.text(resp)
      my_canvas.show()    
  # Save the response
  self.experiment.set("response", resp)
  

  Good luck!
