  Hello,

  I don't think you can avoid having to program a bit yourself. However, it is not that hard, and there are many discussions dealing with this topic here in the Forum.

  As a starter, you could have a look on this discussion here : http://forum.cogsci.nl/index.php?p=/discussion/1415/solved-slider-and-touch-screen/p1

  It describes rather detailed how to implement a horizontal slider. All you would need to do, is finding and swapping the x and y coordinates accordingly.

  I hope this is what you had in mind?

  Give it a shot, and if you need more help, just ask again.

  Good luck ,

  Eduard

  Thank you for your reply. Main idea is to force slider to move upwards while mouse moves upwards, opposite direction accordingly. I`ve tried to change code but have only achieved mouse movement inversion. It looks like slider moves only in x axis. Main goal is y axis increment.

  This should do the trick, but you probably need to tweak the code a bit to make it prettier.

  from openexp.canvas import canvas
  from openexp.mouse import mouse
  my_canvas = canvas(self.experiment)
  my_mouse = mouse(self.experiment, timeout=20)
  
  # Set slider dimensions
  slider_w = 500
  slider_h = 100
  slider_x = self.get("width")/2-slider_w/2
  slider_y = self.get("height")/2-slider_h/2
  
  while True:
          # Determine the slider fill based on the mouse position
          pos, time = my_mouse.get_pos()
          x, y = pos
          # If you want to re-enter the slider loop, you need a variable that can be True
          # or False. Initialized as being False. Only if mouse on slider, it becomes True
          enter = False
          if not (x < slider_x - slider_w/2) or (x > slider_x + slider_w/2):
                enter = True
  
          while enter:
  
              # Determine the slider fill based on the mouse position
               pos, time = my_mouse.get_pos()
               x, y = pos
  
               # Break when the mouse leaves the slider area
               if (x < slider_x - slider_w/2) or (x > slider_x + slider_w/2):
                    break
  
               slider_fill = min(slider_w, max(0, y-slider_y))
  
               my_canvas.clear()
               # Draw some text (this can be anything)
               my_canvas.text("Question goes here", y=slider_y-100)   
               my_canvas.text("Click to accept ...", y=slider_y+100)
               # Draw the slider frame
               my_canvas.rect(slider_x, slider_y, slider_h, slider_w)
               # Draw the slider fill
               my_canvas.rect(slider_x, slider_y, slider_h, slider_fill, fill=True)               
               # Draw the mouse cursor 
               my_canvas.arrow(x+5, y+10, x, y)
               my_canvas.show()
  
          # Poll the mouse for buttonclicks
          button, position, timestamp = my_mouse.get_click(timeout = 20)
          if button != None:
              break
  
  slider_percent = 100.0*slider_fill/slider_w     
  self.experiment.set("slider_percent", slider_percent)

  I would like to thank you so much. With your hints I have achieved more than I expected first. Quite amazing OpenSesame actually is.
  
  The only problem left to solve is output data. Currently after clicking exported csv file is completely empty. I have not dug deeply into documentation yet.
  Thank you once again!

  Nice to hear.

  You probably wanna have a look at the logger item (See here)
