So first of all I'd like to say hi to the community here because I'm pretty new. I understand the language enough to work with but I don't understand how to work with the GUI as I haven't seen any good documentation explaining how to program with the GUI.

I wanted to make a simple program where I can input text in a text field and then when I click enter, what I typed appears in a label above. Every time I enter a new text and click enter, I want it to add on this text to the old one in the label above, but in a way so that every new text is on a new line. Can anybody please help me with this. Thanks in advance for your time and I'm really enjoying the app!

I have several projects using the UI module that may help:

ui-tutorial is maybe also a good start...

import ui

def button_tapped(sender):
    view['labelname'].text += 'hello\n'

view = ui.View()
view.background_color = 'white' 
label = ui.Label()
label.name = 'labelname'
label.frame = (50,50,200,200)
label.border_color = 'lightgrey'
label.border_width = 1
label.number_of_lines = 0    #most important line!!!
label.corner_radius = 5
label.text = ''
view.add_subview(label)
button = ui.Button(title='Add hello!')
button.frame = (50,251,200,100)
button.border_color = 'blue'
button.border_width = 1
button.corner_radius = 5
button.action = button_tapped
view.add_subview(button)
view.present('fullscreen')

Wow @TutorialDoctor. Just down loaded and ran the Web Browser tutorial. Very Nice.

@NickAtNight, that tutorial isn't mine but it is nice. Hehe. Someone named humberry.

import ui

w, h = ui.get_screen_size()

def textfield_action(sender):
    sender.superview['textview'].text += sender.text.strip() + '\n'
    sender.text = ''

view = ui.View(name='Type text in the textfield and hit return...')
view.add_subview(ui.TextView(frame=(0, 50, w, h-50), name='textview'))
view['textview'].editable = False
view.add_subview(ui.TextField(frame=(0, 0, w, 50), name='textfield'))
view['textfield'].action = textfield_action
view.present()

Thanks for all the response everyone!
