Detect A RETURN keypress to run function.

[starrshaw]

Hi All, I hope you are all having a great holiday! If you like me you having fun with your iPad and Pythonista!

I have been looking everywhere and can not find a way to detect a RETURN keypress to run a function. Do not know if that is OS specific or not...

?

Thanks!

Where exactly do you want to detect a Return key press? If you want to read text input from the user, you can use Python's input (Python 3) or raw_input (Python 2) function. This is a standard Python function, so it works on all systems, including Pythonista.

Hi dgelessue, thanks!

I already get input from a user via a ui TextField and pass to a function when a Button is pressed, which works fine. But, just in case a user wanted to use the keyboard instead of the button, I wanted to have an option to press a Return Key..

ui.TextFields have an action attribute, which you can set to a function, which is called when you press Return in the text field (either on the onscreen keyboard or on an external Bluetooth keyboard). By default I think this doesn't unfocus the text field, so you might want to call end_editing() on the text field, so the onscreen keyboard goes away when pressing Return.

Thanks dgelessus! That works great!
