r0x0r / pywebview Goto Github PK

I'm using Windown 7 64-bit. I installed pywebview with pip.
With Python 3.4.4:

python -c "import webview"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "D:\Anaconda3\lib\site-packages\webview\__init__.py", line 52, in <module>

    import webview.win32 as gui
  File "D:\Anaconda3\lib\site-packages\webview\win32.py", line 24, in <module>
    from win32_gen import *
ImportError: No module named 'win32_gen'

With Python 2.7.1 the import works.
It might be due to relative import issues?

I'd like use this in my project, but one of my functional requirements is a confirm dialog on close.

Is this something that can be easily added?

So I'm testing out pywebview for possible inclusion to a project I'm working on. One of the appeals is its OS agnosticism. I'm trying out the http_server.py example module and I'm getting an exception thrown in winforms.py;Line 48.

C:\...>python webtest.py
Traceback (most recent call last):

SyntaxError: invalid syntax

What seems to be the problem is that the FormBorderStyle enumeration value of "None" is causing errors because that's also a python keyword. I ran a little test in IDLE to further investigate this.

>>> import clr
>>> import System.Windows.Forms as WinForms
>>> test = WinForms.FormBorderStyle
>>> test.None
SyntaxError: invalid syntax
>>> test.Fixed3D
2
>>> test.FixedDialog
3
>>> test.FixedSingle
1
>>> test.FixedToolWindow
5
>>> test.Sizable
4
>>> test.SizableToolWindow
6

Let me know if I'm missing something.

I get a series of SyntaxError exceptions (see below for an example) when I create a window under Windows 10. It happens with any URL I load. Here is an example of the code:

import webview
webview.create_window("title", "http://google.com")

Mathjax script doesn't load at all on webview which otherwise is working properly on other cases and browser. Can you please check if its ok in your case too?

I was getting an error that 'PyQt5 was not found' and also This module requires PyQt4 or PyQt5 to work under Linux. even though it was actually installed on my Linux Machine (Arch Linux), this is due to the fact that QtWebKitWidgets has been deprecated in Qt 5.5 and eventually removed in Qt 5.6 in favour of QtWebEngineWidgets, all this came from an ImportError that was raised when QtWebKitWidgets wasn't found in PyQt5. it's likely to affect Arch Linux / Fedora users or other users who run an updated version of Qt5 for some reason (Kde5 maybe)

I've already made a PR to address this
This commit fixed an issue when trying to import PyQt5 #47
#47

This project looks very interesting and promising but I have no clue how to get it up and running despite a ton of wrangling/effort. The issue lies with finding the correct module/library called WebKit for python (I believe I need to install either Gnome/webkitgtk/pywebkitgtk or something to that nature)....

Here's where webview.py is calling that "WebKit" module in your code:

# Mac imports
if platform.system() == "Darwin":
    # Import PyObjC modules
    from Foundation import *
    from AppKit import *
    import WebKit
    logger.info("Using Cocoa")
    _create_window_func = "_create_window_mac"

And here's the error I'm encountering pops up(FYI):

Any help or direction would be great --- also Windows support would be awesome (I tend to build things that are multi-environment friendly)

Thanks,

The culprit is the win32com.shell import. See pyinstaller/pyinstaller#1322 for more details. There is currently no resolution for this problem on the PyInstaller end.

One workaround is to remove this import and the related code (see win32.py, lines 182-186). win32com.shell functionality is required by open folder dialog. So if you don't use it, this will do the trick.

Since no matter what, you need pywin32 and comtypes, is there an appreciable difference to users between using pythonnet (and the .NET API) or not (and the Win32/COM API)?

Introduce a toggle_fullscreen() function that would toggle fullscreen mode on a currently active monitor. Currently the fullscreen mode on startup is activated on a primary monitor and there is no way to force it on another monitor.

It would be great to have an "About" menu in the new default application menu.
This could display the app icon, the application name and some copyright and license infos.
E.g. a link to pywebview including its license could be added to this menu.

Hi, THANKS for such module.

Is there any event like when a user close the window the event will trigger? I have a bottle server running so what i wanted to do is when the user close the app the server will be destroyed on closing the app.

Hi. I've been working on a production level project for a while now involving pywebview. The client and I recently noticed that one of the html files displayed is lacking certain features when displayed in pywebiew. The features are present when it's opened in any browser. I'm uploading screenshots and the html files in hope that it can be fixed. I tested this error by opening the html files with a python shell command copied from the quickstart, so it's not other code in my program.

Hi,

When resize is set to True, the webview window can be resized, but the underlying browser instance does not resize with it. See the screenshot below:

It seems a pity I'm only getting in touch when something is going wrong, but pywebview is sensational!

with thanks

This lib is fantastic, still I'm not finding a way to get the html or the content of the page to my program. I need this because I need to sent it to a printer.

Application icon displayed in the taskbar / application window must be defined in application code. In contrast the icon displayed in Explorer is specified by freeze framework (eg. py2exe).

I have created a div with overflow-y:auto; which creates a scroll in div, when extra elements are there in that div,

Problem is, the scroll stops in between when you scroll up or down.

I am on Mac Os x el capitan.

Between Awesome work, thanks

Hello, I'm having some beginner problems with this. Any help greatly appreciated.

I'm on ubuntu 14.04 LTS, using a python 2.7 virtualenv setup. I installed the module via pip install pywebview.

I'm running the following simple example:

import webview
webview.create_window('It works, Jim!', 'http://www.flowrl.com')

and getting the following exception:

When I create a window in full screen mode, it's stuck in the corner as pictured in the screenshot. I've racked my brains and the web, but nothing works. My attempted fixes include scaling my display res down to 1920*1080 in case it didn't support 4k, running the file in a wide variety of different ways, using different html files, and using gtk instead of qt. So far none have worked.

According to issue #5 ,in Windows XP, python 2.7

File "C:\Python27\Lib\site-packages\webview\win32.py", line 306, in get_ie_mode
    except FileNotFoundError:

Solved by adding a line here:

    try:

        FileNotFoundError = WindowsError # There is no FileNotFoundError in Python 2.x
    except ImportError:
        import winreg  # Python 3

I am using PyInstaller to package my application as an executable.
It packages fine, and no special instructions are required for pywebview.
However, when executing the program, it fails to find the icon resource. (win32.py line 98).
I guess it should be possible to configure something on pyinstaller parameters, but it would be nice to just have an option to not load an icon for pywebview.
(As a workaround I am currently just commenting this line from win32.py: self.wndclass.hIcon = win32gui.LoadIcon(self.wndclass.hInstance, 1))

When using QT4 vertical scrollbar is always present, no matter how big viewport is. Screenshot attached.

Hello!

When I run pywebview inside a virtualenv everthing seems to work fine. However, recently i started using virtualenvwrapper instead and suddenly I get this:

I'm on Arch using Python 3.5.2, python-gopbject 3.22.0-1 and pywebview 1.2.2

Hi, I'm running the newest version of python (3.5.1 i think) and the example is giving me stack traces.

import webview

webview.create_window("It works, Jim!", "http://www.flowrl.com")

prints lots of these to stderr (the program does keep running):

And they just keep coming after each

This feature will probably change the API significantly, but I wanted to at least document the need.

Essentially my idea would be that the webview.create_window() function returns a window handle or maybe even a BrowserView object that can be manipulated directly. That way you could instantiate multiple windows and destroy them individually.

Perhaps the app can quit when the last window is destroyed, or maybe there could be a 'master' window instance that can control all the other ones.

I'm kind of spit-balling but hopefully you get the idea. Could pywebview support multiple windows? Can you think of some other way to do it that doesn't involve a major API change?

Right clicking on the browser container generates a context menu on every platform. They must be disabled in order to hide implementation details and prevent unwanted actions such as page reload. Any input on how this could be achieved on any platform is appreciated.

I am testing pywebview in order to make a simple digital signage application.

Webview shows most of the urls ok (even youtube fullscreen videos!), but when I give it a jpg or png url (local or http), a Segmentation Fault error comes out.

I am using ubuntu 14.04.

at the moment the user can resize to whatever they like, and this can be a bit funny:

low priority i know!

thanks

Seems pywebview requires PyObjC, and when you import webview into your Python 3.5 code with pyobjc version 3.0.4, you run into the error message "Symbol not found: _PyObject_REPR".

You need to upgrade to pyobjc version 3.0.5 or later to fix this.

At the time of this writing, 3.0.5 has not officially been released, yet, so you can either wait for the official release or install a pyobjc beta like:

pip3 install -U https://github.com/GreatFruitOmsk/pyobjc-core/releases/download/v3.0.5.dev0/pyobjc-core-3.0.5.tar.gz

Take care, that's a third party install location.

The version of PyGObject on PyPI is extremely old (last upload was 2011) and fails to install under Python 3 due to a syntax error. This makes pywebview unusable in a virtualenv (unless using the --system-site-packages option) or when using something like Anaconda rather than the system Python. Possible solutions:

• Switch to Qt as the default on Linux since PyQt4/5 are installable via pip (possibly just for Python 3)
• Don't explicitly require pygobject in setup.py but instead add installation instructions that note needing to use the system package for Linux

A common pattern for Mac applications is to have an application menu available to perform functions like quitting the application or viewing the 'About...' menu. I've attached a screenshot of the application menu from a sample application packaged with py2app to show what it normally looks like.

In apps that are created with pywebview and packaged with py2app the application menu isn't accessible. The app name appears in its usual place but clicking it does not produce a menu. Is there a way to enable this functionality?

Running windows XP, Python 3.3, attempting to create a window returned the error:

            # Set window style
            style = win32con.WS_VISIBLE
            if self.resizable:
                style = style | win32con.WS_OVERLAPPEDWINDOW
            else:
                style = style | (win32con.WS_OVERLAPPEDWINDOW ^ win32con.WS_THICKFRAME)

            #  Center window on the screen
            screen_x = _user32.GetSystemMetrics(win32con.SM_CXSCREEN)
            screen_y = _user32.GetSystemMetrics(win32con.SM_CYSCREEN)
            x = int((screen_x - self.width) / 2)
            y = int((screen_y - self.height) / 2)

I have dual screens on my computer and i would like to have pywebview to run fullscreen on the secondary screen instead of the primary screen. It would be nice if there's option to run full screen on my secondary screen on the right, etc.
e.g. webview.create_window("Full-screen browser", "http://www.flowrl.com", left=1024, top=0, fullscreen=True)

Please add a load_string method for when the HTML is stored in memory.

I tried to create a window in fullscreen but it doesn't work for me, it creates a 800x600 window

Hi,

When I send a request from a controller in the web.py webserver (running in its of thread) I get the following error:

INFO:requests.packages.urllib3.connectionpool:Starting new HTTPS connection (1): web.site.example
ERROR:comtypes._comobject:Exception in DWebBrowserEvents2.DocumentComplete implementation:
Traceback (most recent call last):
File "comtypes_comobject.pyo", line 147, in call_without_this
File "comtypes\client_events.pyo", line 117, in error_printer
File "webview\win32.pyo", line 273, in DocumentComplete
AttributeError: 'BrowserView' object has no attribute 'browser'

Do you have any idea why this error is thrown on Windows 2003 / 2012? When I run the App in Pycharm in combination with Linux everything works like a charm...

This is the code that I'm using for the request:

import web
import json
import requests
from requests.auth import HTTPBasicAuth


class ApiSettings:

    def GET(self):
        practice_number = web.input().practice_number
        data = {
            'status': 404,
            'message': '',
            'data': {}
        }

        if len(practice_number) == 4 and practice_number.isdigit():

            r = requests.get('https://web.site.example/something'.format(practice_number),
                             auth=HTTPBasicAuth('user', 'password'))

            if r.status_code != 200:
                data['status'] = r.status_code
                data['message'] = 'Can\'t retrieve data'
            else:
                 response = r.json()

                 data['status'] = response['status']
                 data['message'] = response['message']

        web.header('Content-Type', 'application/json')
        return json.dumps(data)

Thanks for looking at this :)

Win32 API in Windows 10 has only support for MSHTML missing out new features of EdgeHTML. EdgeHTML can apparently be embedded only using .NET, unless it provides a COM interface. If the .NET route is chosen, then Python for .NET seems to be a right tool for the job.

Chrome Embedded Framework (CEF) could be a great alternative to IE based renderer on Windows systems. There are Python bindings for CEF found here https://github.com/cztomczak/cefpython, as well as some examples on how embed CEF with various GUI toolkits.

The generated code in the current version of comtypes does not provide support for Python 3. As a result the following error is thrown, when comtypes code is invoked on Windows

True = 1
^
SyntaxError: can't assign to keyword

The fix has been made to the comtypes master branch, but there is no release yet. As a workaround you have to monkey-patch the comtypes code located in PYTHON_FOLDER\lib\site-packages\comtypes\tools\codegenerator.py with the following diff.

hi,

when i first launch my application, the content isn't sized correctly to begin with. about 20 pixels are outside the view port to the right and to the bottom. if you look at the following screenshot, you can see a line of pixels at the right belonging to the scrollbar which is mostly outside the view port.

if i resize the window just slightly, by a single pixel, it resizes the content to the viewport correctly. see this next screenshot.

i appreciate this may be a bug in upstream, i.e. in the activex control container (or whatever you use), but perhaps this could be worked around by sending a resize message to the control after it is made visible? just a thought. (i always get annoyed when people who have no idea how my software works, make suggestions for how i can fix things; so i probably shouldn't make these suggestions :P )

once again, thank you for all your work on pywebview!
