webview-python's Introduction

webview

Python extension that provides API for the webview library.

Getting started

Install the bindings:

pip install webview

Try the following example:

import webview

w = webview.WebView(width=320, height=240, title="Hello", url="https://google.com", resizable=True, debug=False)
w.run()

You may use most of the webview APIs:

# Change window title
w.set_title("New title")
# Make window fullscreen
w.set_fullscreen(True)
# Change initial window background color
w.set_color(255, 0, 0)
# Inject some JS
w.eval("alert('hello')")
# Inject some CSS
w.inject_css('* {background-color: yellow; }')
# Show native OS dialog
file_path = w.dialog(0, 0, "open file", "")
# Post funciton to the UI thread
w.dispatch(some_func)
w.dispatch(lambda: some_func())
# Control run loop
while w.loop(True):
  pass

Dispatch is currently only a stub and is implemented as direct function call. Also, proper Python-to-JS object mapping is not implemented yet, but is highly

Development

To build and install the library locally:

python setup.py install

To upload a new version:

python setup.py sdist
twine upload dist/webview-*.tar.gz

To build and install it locally:

python setup.py install

Please, ensure that all sources are formatted using yapf.

Win32 build adjustments

First, thanks for the nice work :) I'm writing thise issue for potential future reference/memory as this repo is mentionned as "Python bindings" in the webview repo

I've been giving webview-python a try on Win32, and I had to make some adjustments to get the build running - see below.

Also, the current master (2e5462f from July 2018) embeds IE11, which is well deprecated/abandonned now (2021).

I am getting this error, what should I do?

`.bind` implementation

Are there plans to eventually provide an implementation for WebView.bind?

Unable to run it under macOS

Hi, Thank you for the webview implementation on go/c++/python.

On macOS 10.12.6, I tried to use pip install webview or pip3 install webview, it gives compilation error on webview.h.

So I cloned the repository and tried pip setup.py install, it again gave compilation error. It seemed to me the webview.h is not the same as the one for go/c++, so I copied webview.h from there, resolved signature differences with webview.c, then it was successful.

But when I run sample code it gives runtime error:

2019-01-20 14:47:44.404 Python[14194:118019] *** NSForwarding: warning: object 0x7fa279c31240 of class '__WKPreferences' does not implement methodSignatureForSelector: -- trouble ahead

Trace/BPT trap: 5

on the line w = webview.WebView(width=320, height=240, title="Hello", url="https://google.com", resizable=True, debug=False)

Is it possible to get it working?
