问题 I made a simple offscreen renderer with cefpython. I used cefpython.MessageLoop() but I would like to execute a javascript function with browser.GetFocusedFrame().ExecuteFunction which must be called from main UI thread. Is there a way to set a callback on cefpython's message loop? Alternatively I could use MessageLoopWork , but I don't know how. I tried to call it in a separate thread but it does not work: import threading def main_loop(): cefpython.MessageLoopWork() threading.Timer(0.01,

问题 I made a simple offscreen renderer with cefpython. I use cefpython.MessageLoop() , and I have a separate thread to do something every seconds: [... cefpython initialization ...] startTime = time.time() def main_loop(): print time.time() - startTime threading.Timer(1, main_loop).start() main_loop() cefpython.MessageLoop() This works fine, but it slows down after 30 seconds (then the loop updates every 10 seconds). This is the output that I get: [CEF Python] Initialize() called [CEF Python]

问题 I'm trying to make a hybrid python-js application with cefpython. I would like to have: JS and HTML files local to the cef python app (e.g. in './html', './js', etc) Load one of the HTML files as the initial page Avoid any CORS issues with files accessing each other (e.g. between directories) The following seems to work to load the first page: browser = cef.CreateBrowserSync(url='file:///html/index.html', window_title="Rulr 2.0") However, I then hit CORS issues. Do I need to run a webserver
