Usage 🛠️

Creating a Basic Application

from pylon import PylonApp

app = PylonApp(single_instance=True)

# set icon
if (is_production()):
    app.set_icon(os.path.join(get_production_path(), "icons/icon.png"))
else:
    app.set_icon("src-pylon/icons/icon.png")

# create window
window = app.create_window(
    title="Pylon Browser1",
    js_apis=[CustomAPI()],
    dev_tools=True
)

window.set_size(800, 600)

# load html
if (is_production()):
    window.set_dev_tools(False)
    window.load_file(os.path.join(get_production_path(), "src/index.html"))
else:
    window.load_file("src/index.html")

# show window
window.show_and_focus()

app.run()

Setting Up System Tray

from pylon import TrayEvent

def on_double_click():
    print("Tray icon was double-clicked.")

app.set_tray_actions({
    TrayEvent.DoubleClick: on_double_click,
})
app.set_tray_menu_items([
    {"label": "Show Window", "callback": app.show_main_window},
    {"label": "Quit", "callback": app.quit},
])
app.setup_tray()

// CustomAPI method usage example
document.addEventListener('pylonReady', function () {
  // Using the echo method
  pylon.CustomAPI.echo('Hello', 42).then((result) => {
    console.log(result); // "Message received in Python: Hello, 42" output
  });

  // Using the getAppVersion method
  pylon.CustomAPI.getAppVersion().then((version) => {
    console.log('App version:', version); // "App version: 1.0.0" output
  });

  // Example using async/await syntax
  async function useCustomAPI() {
    const echoResult = await pylon.CustomAPI.echo('Test', 100);
    console.log(echoResult);

    const appVersion = await pylon.CustomAPI.getAppVersion();
    console.log('Current app version:', appVersion);
  }

  useCustomAPI();

  // Button click event binding
  document.getElementById('myButton').addEventListener('click', function () {
    // Using the create_window method
    pylon.CustomAPI.create_window().then((windowId) => {
      console.log('New window ID:', windowId); // "New window ID: [generated window ID]" output
    });
  });
});

Using React

import { StrictMode } from 'react';
import { createRoot } from 'react-dom/client';
import App from './App.jsx';
import './index.css';

document.addEventListener('pylonReady', function () {
  createRoot(document.getElementById('root')).render(
    <StrictMode>
      <App />
    </StrictMode>
  );
});

function App() {
  console.log('Pylon is ready');

  window.pylon.CustomAPI.getAppVersion().then((version) => {
    console.log('App version:', version); // "App version: 1.0.0"
  });
  return <h1>Hello World</h1>;
}
