    Hmm, it looks there's an older post about this here - with a good example.
    https://forum.omz-software.com/topic/2049/possible-to-subclass-uiview-and-redefine-keycommands-property/7

    #UPDATE

    The code linked works after minor changes (print, Python3)
    While the example catches keys with a modifier, setting the modifier to 0
    makes it possible to catch normal keys and it's possible to catch the
    Enter key via chr(13).

    So while this looks do-able, the question is if this is a good approach:

    One problem with it is that I haven't found out how to trigger updates on
    the main view from the function that collects the keys. In my example,
    I'm trying to update a label on the view (form) with the number that is scanned.
    I've looked at the ui examples, where there's a "sender.superview" that
    allows to connect to the other elements of the view.
    Here the keyboard control is added as a Subview to the main view, so that doesn't work.

    Hi,

    I'm trying to understand how I can catch keyboard inputs in a ui reliably.

    When I place a textbox on a form, i need to tap it to make it accept keys.

    My use case:

    I have a bluetooth keyboard connected to the ipad. (Actually, it's a hardware barcode laser
    scanner that acts like a bluetooth keyboard and types any number it scans)

    My aim is to accept any number 0-9 and the enter key always, no matter where the focus is.
    Whenever enter is recognised, I would then collect the typed number and so something with it.

    When developing desktop programs, I can force focus to a textbox from
    code, so I don't have to click on it and any scanned number will go in there.

    What is the best approach in Pythonista?

    I'd prefer not having a textbox at all - and just get all keypresses on a UI.

    Hi,

    I'm trying to write some simple prototypes which I would like to hand out to people to test on some Iphones I give them. These are old Iphone5 with iOS 10.2 and just pythonista installed.

    It's a simple GUI, with some text fields and some buttons.

    Is is possible to write the code in a way that it's not possible to close the window without killing it?

    As a bonus question, can I code protect Pythonista on those devices so that the test user cant access the code at all? Or is there a way to convert the prototype to a real app if approved?
