kandi X-RAY | pywebview Summary
pywebview is a lightweight cross-platform wrapper around a webview component that allows to display HTML content in its own native GUI window. It gives you power of web technologies in your desktop application, hiding the fact that GUI is browser based. You can use pywebview either with a lightweight web framework like Flask or Bottle or on its own with a two way bridge between Python and DOM. pywebview uses native GUI for creating a web component window: WinForms on Windows, Cocoa on macOS and QT or GTK on Linux. If you choose to freeze your application, pywebview does not bundle a heavy GUI toolkit or web renderer with it keeping the executable size small. pywebview is compatible with Python 3. pywebview is created by Roman Sirokov.

QUESTION
I have a webview that controlling the flask api.
The webview will have a button to start the flask server and a button to stop the server. That is why I have to use multiprocessing.Process to create a separate process for Flask. With that, I cannot access my pywebview.Window anymore. I want to use pywebview.Window to evaluate some javascript with pywebview.Window.evaluate_js() within the Flask process (of course it has to be the same pywebview.Window that I already created before open a new process for Flask).
Is anybody know how to accomplish this issue. I appreciate it!
Some sample code:
...ANSWER
Answered 2021-Sep-07 at 13:26I guess I have to use Threading instead of Processing, since Thread is sharing memory and Process is not.
Also, for anybody who want to stop a Thread, here is a function to do that, not sure if this is a good way to do it, but it does the job for me:
QUESTION
So, I have opened windows in pywebview at a time. Now from window 1, I want to click a button and show some texts in window 2. How can communicate between them? I was thinking of using flask-socketio or any socket based solution. But that seems like overkill for this, is it? How can this be easily achieved?
This is the code to open multiple windows in pywebview:
...ANSWER
Answered 2021-Jun-05 at 04:31Well, in the end, I had to go with the hard way (though it was easy), the socket way. I used flask-socketio to implement this feature. Here is an example:
Suppose I have 2 separate windows, Window_1, and Window_2. Now I have a button in Window_1, from where I will click a button and a pop-up will show in Window_2.
Window_1.html
QUESTION
Info in advance:
There is a similar question dealing with the same issue.
However, this one doesn't work for me (or I just don't know enough to include it properly).
I have only recently started working with pywebview.
The goal:
I want to close the window / end the programme with a link (or button) in HTML.
The problem:
The code used does not work for me.
The function can be reached (the print statement fills up the console,
unfortunately I have no idea why), but the window is not closed.
I am just starting with pywebview, so I don't really know what to do.

Answered 2021-May-20 at 08:57In the meantime I have found a solution that closes the window and exits the program.
However, I get an error, unfortunately I do not know why.
The HTML / JS code is correct so far and needs no adjustment.
In the Python script, only def destroy(self) must be specified instead of def destroy(window).
Pretty simple actually, but still took me almost a month to solve.

My Goal:
Bundle a simple pywebview application as a standalone executable (one file) on Linux (specifically Arch Linux). The binary executable size must be no greater than 30MB. Code is below.
The Problem:

- Create a virtual machine with Ubuntu Linux inside of virtualbox
- Delete all themes in
/usr/local/themesand all icons in/usr/local/iconsexcept thedefault/folder - Then, try using pyinstaller again
- Your binary will be around 80 MB in size (37x smaller)

I'm quite a noob at any development at all. So I apologize ahead of time if I'm missing something very trivial.

QUESTION
I am not really sure how can I use the HTTP Requests 's response to show the widget.
The problem is that when I am requesting GET in http link and it returns a html response; but when I try to render the html part of where the widget is, the pywebview throws off error like
A Server error occurred. Please contact the administrator.
Or it shows the values of the html's tag not the html webview itself
Code for reference:
...ANSWER
Answered 2020-Jul-13 at 10:48If you ever stumbled upon this question. I have already solved this a week ago.
The solution I used is to run a custom JS script using Pywebview:
Question #1 Is there any python framework that renders HTTP response especially the Captcha widget?
Answer: You have to do it by yourself.
Question #2 What's the best way to handle this problem?
Answer: Fetch the widget's location then manually load it to webview. Then after that just get the payload using JS:
window.evaluate_js("document.querySelector('#g-recaptcha-response').value")
Question #3 How can I store the session to webview response?
Answer: You can't. But maybe you can inject the session using the pywebview's API.
Question #4 How can I access the previous session that was generated from HTTP Request.
Answer: This is almost same as the question #3. Maybe we can just fetch the session manually then store it to the pywebview's API.
Hope anyone helps this.
QUESTION
So my next assignment for school involves creating a python GUI app with a database. I just have a couple basic questions that I am not yet 100% sure on the answers to.
- I'm very good with
HTML&CSS, however not so good atJavascript(I have about 8 weeks for this project however) - is creating an app withElectronJSor even just in the web browser withpywebviewa good idea or would I be best to stick with some of the older, uglier GUI frameworks such asTkinterorKivy? - Is there any major reason to learn how to use
NoSQLdatabases overSQL? I already have a fairly decent understanding of SQL. - And finally, does using a GUI and a database (can the database even be inside the
.exe?) pose any issues with packaging my whole project into a.exeor.appat the end or is this nothing to worry about?
Thanks in advance :)
...ANSWER
Answered 2020-Jun-10 at 05:081- As gui with python goes i have mostly worked with pyqt5, its pretty good, it is a mature project, you can even use it to comunicate with the database (sql databases) you can install the qt desigmer for a fast ui design, can apply css (or something really close to it) to your ui components and most important (at least for me) you will find a good amount of resources online on how to work with it and solve any issues that may arise.
Still if you want to go for a more electron like aproach and put your html and css skills to use, i would recomend Eel, it is fairly easy to use, i havent created anything too complex with it. Now these gui libraries that i mentioned , can be used with the module pyinstaller to create the executables that you need.
2- If you already have some experience with sql, i recomend that you go with it for two reasons First: sql database engine will fill most of your needs (if not all), go with nosql if you are dealing with huuuge amounts of data or you really want to learn nosql. Second:I dont know if your project is going to comunicate with an external database or is embeded in the project, if it is embeded go with sqlite, if not, for sql i recomend postgres and for nosql use mongodb.
3- from my experience, sometimes it can get complicated trying to embed everything (database, other external files) within the executable but you can build the app to be in separated files, i recomend that you use for this like i wrote above pyinstaller, it is wel documented and both gui libraries work fine with it. Hope this helps, everything i recomended to you is from personal expierience, there are plenty of database engines, python libraries you can use for the tasks needed to complete your project, check what suits you the best.
Good luck, sorry for my english.
