Asciimatics doesn't print anything.

[Ivan]

Describe the bug
If I run something, terminal screen just blink one time and script stop working.

To Reproduce

from asciimatics.widgets import Frame, Layout, Button
from asciimatics.screen import Screen 

def main(screen):
    frame = Frame(screen, 80, 20, has_border=False)
    layout = Layout([1, 1, 1, 1])
    frame.add_layout(layout)

    layout.add_widget(Button("Button 1", lambda: print("Button 1 pressed")), 0)


Screen.wrapper(main)

Expected behavior
It must create button.

Screenshots

I wrote there "python main.py"

System details (please complete the following information):

• OS and version: Windows 10
• Python version: 3.9.13
• Python distribution: Python 3.9.13 (python -V)
• Asciimatics version: 1.14.0

You haven't created a Scene and then told the screen to play it. Take a look at

asciimatics/samples/contact_list.py

Lines 175 to 180 in 31b3fe5

 scenes = [ 
     Scene([ListView(screen, contacts)], -1, name="Main"), 
     Scene([ContactView(screen, contacts)], -1, name="Edit Contact") 
 ] 
  
 screen.play(scenes, stop_on_resize=True, start_scene=scene, allow_int=True)

from asciimatics.widgets import Frame, Layout, Button
from asciimatics.screen import Screen
from asciimatics.scene import Scene

def main(screen):
    frame = Frame(screen, 80, 20, has_border=False)
    layout = Layout([1, 1, 1, 1])
    frame.add_layout(layout)

    layout.add_widget(Button("Button 1", lambda: print("Button 1 pressed")), 0)

    screen.play([Scene([frame])])


Screen.wrapper(main)
