  I did it once, I used

  textInputDialog:setInputType(TextInputDialog.PHONE)

  @pie close, but i think it also has some additional not needed characters so it would be nice somehow to restrict that when those are pressed then nothing is written.

  I think that I was sanitizing the string afterwards, but another option might be to add a "+/-" button near your inputText that switches the sign.
  If you make use of embedded keyboards I don't think you can change their layout, since they are native android/ios (and on laptop you always have the option to add unexpected chars, so you would always need to sanitize).
  On imgui you can sanitize on the run if I am not mistaken (if I recall there is an inputtext callback on text update), but you are still bound to the native keyboards layouts and chars. Another option might be to draw your own keyboard as nicke did years ago in his layout system.

  thanks @pie , yes, i added a sanity check like "if tonumber(value) ~= nil then". also a manual keyboard with imgui would do even better but it is not that important that i want to invest that much time. thanks
