# webview_python A lightweight Python binding for creating native GUI applications using web technologies. Uses WebView2 on Windows and native webview implementations on other platforms. ## Features - Cross-platform support: - Windows: Microsoft Edge WebView2 engine - macOS: WebKit - Linux: GTK-based WebKit - Simple and intuitive Python API - High performance with minimal resource usage - Two-way JavaScript bridge - Easy installation with minimal dependencies ## Why Another Binding? Existing Python WebView solutions have limitations: - [webview-python](https://github.com/zserge/webview-python https://github.com/zserge/webview-python) - Hasn't been updated in 6 years, compilation issues, doesn't use WebView2 - [pywebview](https://github.com/r0x0r/pywebview https://github.com/r0x0r/pywebview) - Complex setup and installation issues ## Installation ```bash pip install webview_python ``` ## Usage ### Display Inline HTML ```python from webview.webview import Webview from urllib.parse import quote html = """ <html> <body> <h1>Hello from Python Webview!</h1> </body> </html> """ webview = Webview() webview.navigate(f"data:text/html,{quote(html)}") webview.run() ``` ### Load Local HTML File ```python from webview.webview import Webview import os webview = Webview() current_dir = os.path.dirname(os.path.abspath(__file__)) html_path = os.path.join(current_dir, 'local.html') webview.navigate(f"file://{html_path}") webview.run() ``` ### Load Remote URL ```python from webview.webview import Webview webview = Webview() webview.navigate("https://www.python.org https://www.python.org") webview.run() ``` ### Python-JavaScript Bindings ```python from webview.webview import Webview, Size, SizeHint from urllib.parse import quote webview = Webview(debug=True) # Python functions that can be called from JavaScript def hello(): webview.eval("updateFromPython('Hello from Python!')") return "Hello from Python!" def add(a, b): return a + b # Bind Python functions webview.bind("hello", hello) webview.bind("add", add) # Configure window webview.title = "Python-JavaScript Binding Demo" webview.size = Size(640, 480, SizeHint.FIXED) # Load HTML with JavaScript html = """ <html> <head> <title>Python-JavaScript Binding Demo</title> <script> async function callPython() { const result = await hello(); document.getElementById('result').innerHTML = result; } async function callPythonWithArgs() { const result = await add(40, 2); document.getElementById('result').innerHTML = `Result: ${result}`; } function updateFromPython(message) { document.getElementById('result').innerHTML = `Python says: ${message}`; } </script> </head> <body> <h1>Python-JavaScript Binding Demo</h1> <button onclick="callPython()">Call Python</button> <button onclick="callPythonWithArgs()">Call Python with Args</button> <div id="result"></div> </body> </html> """ webview.navigate(f"data:text/html,{quote(html)}") webview.run() ``` ## API Overview - `Webview()`: Create a webview instance - `webview.navigate(url)`: Navigate to URL or load HTML content - `webview.bind(name, func)`: Bind Python function to JavaScript - `webview.eval(js_code)`: Execute JavaScript code - `webview.run()`: Start the webview main loop - `Size(width, height, hint)`: Configure window size - `SizeHint`: Window size hint constants ## Contributing Contributions are welcome!
