  Hi Merel,

  Right now the virtual keyboard is only applicable when running experiments on Android. What exactly do you want to do? Of course, you could implement something like an on-screen numpad with a bit of scripting.

  Cheers,

  Hi Sebastiaan,

  Thanks for your reaction! Ah, allright that explains why it didn't work. I have a new idea, maybe I can make it work by showing a numpad made out of butons a couple of times in a row, which gives the participants the 'illusion' of using a numpad. Because, it is not possible to press more than one button in the same widget right?

  Something like this:

  labelQuestion = widgets.label(form,text=equation)
  button0 = widgets.button(form, text='0', var='response')
  button1 = widgets.button(form, text='1', var='response')
  button2 = widgets.button(form, text='2', var='response')
  button3 = widgets.button(form, text='3', var='response')
  button4 = widgets.button(form, text='4', var='response')
  button5 = widgets.button(form, text='5', var='response')
  button6 = widgets.button(form, text='6', var='response')
  button7 = widgets.button(form, text='7', var='response')
  button8 = widgets.button(form, text='8', var='response')
  button9 = widgets.button(form, text='9', var='response')
  button_enter = widgets.button(form, text='enter', var='next')
  
  form.set_widget(labelQuestion, (0,0), colspan=4)
  
  form.set_widget(button0, (0,1))
  form.set_widget(button1, (1,1))
  form.set_widget(button2, (2,1))
  form.set_widget(button_enter, (3,1), rowspan = 2)
  form.set_widget(button3, (0,2))
  form.set_widget(button4, (1,2))
  form.set_widget(button5, (2,2))
  form.set_widget(button6, (0,3))
  form.set_widget(button7, (1,3))
  form.set_widget(button8, (2,3))
  form.set_widget(button9, (3,3))
  
  button_clicked = form._exec()

  Hi Merel,

  Using a form to implement a numpad is not a bad idea!

  Because, it is not possible to press more than one button in the same widget right?

  Correct, but you can re-execute the form until the participant presses the enter button. And then you can use the return value of form._exec() to keep track of the response. I modified your script to illustrate the basic principle.

  Cheers!

  from libopensesame import widgets

      margins=(50,100,50,100), spacing=25)
  
  
  equation = '2 + 2 = ?'
  
  labelQuestion = widgets.label(form,text=equation)
  labelResponse = widgets.label(form,text='')
  button0 = widgets.button(form, text='0')
  button1 = widgets.button(form, text='1')
  button2 = widgets.button(form, text='2')
  button3 = widgets.button(form, text='3')

  button9 = widgets.button(form, text='9')
  button_enter = widgets.button(form, text='enter')

  form.set_widget(button8, (2,3))
  form.set_widget(button9, (3,3))
  
  var.response = ''
  while True:
      labelResponse.text = 'Response: %s' % var.response
      button_clicked = form._exec()
      if button_clicked == 'enter':
          break
      var.response = '%s%s' % (var.response, button_clicked)

  Nice addition to show the participants their response! Maybe I should also add something that they can change their response if they accidentally press the wrong button, with a 'backspace' button or something like that. Otherwise it may be a bit confronting for them to see there response

  Jeej adding an extra button and replace the while loop with this works :

  var.response = ''
  while True:
      labelResponse.text = 'Response: %s' % var.response
      button_clicked = form._exec()
  
      if button_clicked == 'enter':
          break
  
      if button_clicked == 'backspace':
          var.response = ''
      else:
          var.response = '%s%s' % (var.response, button_clicked)
