form_text_input mouse-cursor

Hey guys,

after using a form_text_input the mouse-cursor is visible and in the middle of the screen. That could distract our participants. Does anybody know, how I can make the cursor invisible?



  • Hi Artur,

    I can't seem to find a solution: one line that sort seems to be handy:
    which hides the mouse if executed, but it seems that the mouse is called when the text display is executed, which would , I think call for some sort of a custom function, maybe @eduard knows ho this might work

  • Hi,

    One solution (a little ugly though), is to put a mouse response after the form. In that mouse_response change the timeout to 0 and unselect the box for Visible mouse cursor.

    Does that help?


  • Hi All,

    Some time ago I had a similar problem, and (with Eduard's help) we fixed it by adding the following lines at the beginning of the the inline script (on the run sequence) that produces every trial:

        ### Hide Mouse
        ms = mouse()

    If you only use the standard OpenSesame objects, you can simply add an inline_script containing the mentioned lines at the beginning of your trial loop.

    Hope that helps!

  • Brilliant!

  • This doesn't solve the problem of the visibility of the cursor during the text input item though, when I tried these lines they only hide the mouse before or after the text input item, but not during. Guess that is not quite essential though

  • Oh shit,

    Yes, I haven't read the discussion properly (obviously). I'll have a look later today or tomorrow, whether it is something that can be changed.


  • Hi Artur,
    I had the same problem before.
    The inline script should be placed after the form containing text_input.
    Hope that works!


  • Ok,

    The only way I found to fix it, is to modify the source code of Opensesame (just writing a wrapper function does not work as the mouse object is invoked quite deep inside).

    So on your computer you have to find following file: libopensesame/widgits/ In this file you need to comment the lines 173 #self.mouse.show_cursor() and 198 #self.mouse.hide_cursor()

    This should do the trick. However, this changes the mouse visibility for all forms. Therefore, you won't see a mouse in multiple choice items as well (which could be a little annoying). I'll have a look whether the mouse functionality in forms can be improved in future releases.

    GOod luck,


  • That is great Eduard, thanks for looking into it, attached a text file with the code, and full link;

  • Hi guys,

    Just checking, this isn't an issue if I have the form at the end of the experiment right? I just realised I need a quick way to patch demographic questions into my experiments, and so I am thinking I will add age/gender forms to the end. It's an eye-tracking experiment and I don't have a tracker with me so I can't check on my own if the form introduces problems with the cursor (mouse pilot makes the cursor visible anyway)
