How would I do a button on the screen that creates an input when pushed (preferably using scene module, but ui also works)? For example, there are three buttons on-screen, red, green, and blue. If i push the red button, it does the same as if I typed "red" into the input bar.
What do you mean by input bar? Like the Pythonista console?
@Bumbo-Cactoni, tiny example below, using ui because scene does not really have an ”input bar”, and mixing the two is not really the best way to start learning about them.
import ui
class MyApp(ui.View):
def __init__(self, **kwargs):
self.background_color = 'black'
super().__init__(**kwargs)
self.tf = ui.TextField(
frame = (0, 0, 200, 40),
)
self.b_red = ui.Button(
title='red',
tint_color='black',
background_color='lightgrey',
action=self.action,
)
self.b_red.frame = (0, 0, 100, 30)
self.add_subview(self.tf)
self.add_subview(self.b_red)
def action(self, sender):
self.tf.text += sender.title
def layout(self):
self.tf.center = self.bounds.center()
self.b_red.center = self.bounds.center()
self.b_red.y = self.tf.y + 70
MyApp().present('fullscreen')

Thank you!

I meant like @mikael answered. Like the Pythonista console.
@Bumbo-Cactoni well which is it, the textField or the console? 😂
When I say console I mean when you swipe left and go to the screen that has the word “Console” at the top. The input is what you’d usually type on this screen.
There’s ways to make your own buttons/toolbars and ui stuff on the actual Pythonista app itself, and not on a view you present. I was just trying to clarify.
I’m glad @mikael answered your question the way you needed though! 😎
@Bumbo-Cactoni Nicer (not Pythonically speaking) than @mikael 's one 🙄 and ok for all your TextFields, with buttons in keyboard, not in view

I was only humorous and you're to kind to upvote my post.
@cvp, no worries! If you said something nasty, I would know someone had hijacked your user account.
