Creating Your First Cross-Platform App
Let’s start by creating a simple “Hello World” app to get a feel for the development process.
# main.py
from kivy.app import App
from kivy.uix.button import Button
class HelloWorldApp(App):
def build(self):
return Button(text=’Hello, Cross-Platform World!’)
if _ _ name _ _ == ‘ _ _ main _ _ ‘:
HelloWorldApp().run()
Save the above code in a file named main.py and run it using the command:
python main.py
You should see a basic window with a button displaying the “Hello, Cross-Platform World!” text.
Building a Cross-Platform Calculator App
Let’s take things up a notch by creating a cross-platform calculator app.
# calculator.py
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
class CalculatorApp(App):
def build(self):
layout = BoxLayout(orientation=’vertical’, spacing=10)
self.result = Button(text=’0′, font_size=32, size_hint=(1, 0.2))
layout.add_widget(self.result)
buttons = [
[‘7’, ‘8’, ‘9’, ‘/’], [‘4’, ‘5’, ‘6’, ‘*’], [‘1’, ‘2’, ‘3’, ‘-‘], [‘0’, ‘.’, ‘=’, ‘+’]]
for row in buttons:
h_layout = BoxLayout(spacing=10)
for label in row:
button = Button(text=label, pos_hint={‘center_x’: 0.5})
button.bind(on_press=self.on_button_press)
h_layout.add_widget(button)
layout.add_widget(h_layout)
return layout
def on_button_press(self, instance):
current_text = self.result.text
if instance.text == ‘=’:
try:
result = str(eval(current_text))
self.result.text = result
except Exception as e:
self.result.text = ‘Error’
else:
self.result.text += instance.text
if _ _ name _ _ == ‘ _ _ main _ _ ‘:
CalculatorApp().run()
This calculator app demonstrates the potential of Python and Kivy for cross-platform app development.
Run it using the same python calculator.py command, and you’ll have a fully functional calculator on your screen.
