Once I place a TextField on the grid in the .pyui editor, what does the script in the .py file look like to retrieve the text input by the user? An example would be great.

I understand the action attribute that shows when you place a button on the grid but action does not show on a TextField, so I’m not sure how to make it call a function, like button, or store the user input.

Any help would be great.

I used the "Search" feature above to find these last few topics, but the first one I found using Google. I searched for "Pythonista TextField example" without the double quotes. That lead to this forum.

I'd have given an example myself, but while I've written several Pythonista programs now, I still haven't used a TextField. I learned a lot searching for this! Good luck.

@technoway WOW that is way more than I expected! Thank you so much for these references. I will dig in.

To summarize, there are essentially two ways of interacting with a ui.TextField:

1) Set its action attribute programmatically. This is currently not possible in the UI editor, but still easy to do: After loading the view, you can access the text field by its name (given in the UI editor) like this:

def text_field_action(sender):
    print('Text was entered:')
    # `sender` is the text field that caused the action.
    print(sender.text)

v = ui.load_view('myui.pyui') # load the view
tf = v['textfield1'] # Access subview by name
tf.action = text_field_action # Important: No parentheses here!
# ...
v.present('sheet')

1. By setting the text field's delegate. This is a lot more complex, but it allows you to control the behavior of the text field while text is entered (and not just afterwards, like with an action).

@omz Thank you.
