It is possible to make a web page reload using the pywebview library? I mean, I have this code:
import webview
webview.create_window('Woah dude!', 'index.html')
webview.start(http_server=True)
…and I want to reload the web page every five seconds because changes are being made in the HTML file.
I'm a bit late to the party, but my method is a bit different compared to the other solution. You can use Watchfiles which detects changes to your directory.
import watchfiles
def watch_and_reload(window):
for change in watchfiles.watch('directory/to/watch'):
## i couldn't get window.load_url() to actually work so I used this instead
window.evaluate_js('window.location.reload()')
if __name__ == '__main__':
window = webview.create_window('Application', path)
## pass the watch function to the start method
webview.start(watch_and_reload, window, http_server=True)
Though this doesn't terminate the watcher which requires you to kill the process yourself. Here is a version that automatically terminates the process:
import webview, watchfiles, threading
def watch_and_reload(window, event):
for change in watchfiles.watch('file/or/folder/to/watch', stop_event=event):
## using this instead of window.load_url() because that didn't work for me
window.evaluate_js('window.location.reload()')
if __name__ == '__main__':
window = webview.create_window(
title = 'Application',
url = 'path/to/html',
)
## this handles stopping the watcher
thread_running = threading.Event()
thread_running.set()
## using a thread to watch
reload_thread = threading.Thread(
target = watch_and_reload,
args = (window, thread_running)
)
reload_thread.start()
## start the webview app
webview.start(window, debug=True)
## upon the webview app exitting, stop the watcher
thread_running.clear()
reload_thread.join()
print('exitted successfully!')
Try to do this:
import webview
import time
def reload(window):
while True:
time.sleep(5)
window.load_url('index.html')
if __name__ == '__main__':
window = webview.create_window('hello', 'index.html')
webview.start(reload, window, http_server=True)
This will 'reload'the page each 5 seconds. It's not really reloading it, it is basically loading the same url, so it should work.
