kandi X-RAY | cefpython Summary
CEF Python is an open source project founded by Czarek Tomczak in 2012 to provide Python bindings for the Chromium Embedded Framework (CEF). The Chromium project focuses mainly on Google Chrome application development while CEF focuses on facilitating embedded browser use cases in third-party applications. Lots of applications use CEF control, there are more than 100 million CEF instances installed around the world. There are numerous use cases for CEF:. CEF Python also provides examples of embedding CEF for many Python GUI frameworks such as PyQt, wxPython, PyGTK, PyGObject, Tkinter, Kivy, Panda3D, PyGame, PyOpenGL, PyWin32, PySide and PySDL2.

QUESTION
I am new to Cefpython and PyQt5 both. I have tried to follow the tutorial in the cefpython repository. I was trying to embed cefpython inside a pyqt application and haven't achieved any success, what's wrong here?
...ANSWER
Answered 2021-Sep-03 at 07:55The problem is that the QWindow
used to render the browser is hidden. The solution is to create a QWidget using QWidget::createWindowContainer()
and add it using a layout.
QUESTION
I'm on Win 10 with Python 3.9.6 and am trying to create a concurrent.futures.ProcessPoolExecutor
pool with a small size and add a lot of tasks to it which use CEF.
This always works for the first tasks up until the pool size is reached and afterwards every future reports the exception
...ANSWER
Answered 2021-Aug-23 at 20:41CEF does not allow to call Initialize
after calling Shutdown
. See here for more info.
When you have more tasks than worker processes, those tasks are queued to be executed later when a worker becomes available.
The first 2 tasks run ok, because a new process is created for each one of them.
The third task fails because it runs in a process that has already been used (i.e.: initialized).
A quick fix would be to add a guard, for example:
QUESTION

I copied files from https://github.com/cztomczak/cefpython/tree/master/examples/pyinstaller to a a directry named pyinstaller
I made following minor changes to pyinstaller.spec
...ANSWER
Answered 2020-Oct-14 at 11:32This is not really the answer I would like to accept, but it is at least one solution and contains information, that might lead to a better fix, a better answer.
After debugging with strace I found out, that the executable searches many files like for example icudtl.dat
, v8_context_snapshot.bin
, locales/*
were searched in
'dist/cefapp/cefpython3but were copied to
dist/cefapp/`
An ugly work around is to do following after compilation
QUESTION
I'm trying to develop a visualization package based on CEFpython technology, so the function has to access an html file. So the structure of the package is basically:
viz_tool
--> init.py
--> main.py
--> index.html
and in the main.py file, I defined a function:

Answered 2020-May-15 at 21:34Look at the documentation of pkg_resources
.
It has a method called resource_filename
that you can use to get absolute path to any internal module.
