Qt ui file not updating
However, you might experience increased memory usage due to this. It is a known problem but Qt 5.6 brings fixes that justify using it despite the graphic glitch.
NOTICE TO PACKAGERS: Read 3.3.8 news and changelog too. NOTICE TO PACKAGERS: Libtorrent 1.1.x series isn't officially supported yet. It also fixes crashes on launch for some Windows setups. On Windows it uses libtorrent 1.0.9 git f716aef5 with commit 45cff5837f7b4af reverted as this one is causing the crashes. As mentioned earlier, there were reports that the forums from a bunch of bittorrent related sites were hacked.
I have a log file being written by another process which I want to watch for changes.
Each time a change occurs I'd like to read the new data in to do some processing on it. I was hoping there'd be some sort of hook from the Py Win32 library.
You'll have to fill in or change the missing symbols. Qt Core import QFile System Watcher, QSettings, QThread from ui_main_window import Ui_Main Window # Qt Creator gen'd class Main Window(QMain Window, Ui_Main Window): def __init__(self, parent=None): QMain Window.__init__(self, parent) Ui_Main Window.__init__(self) self._file Watcher = QFile System Watcher() self._file Changed.connect(Changed) def file Changed(self, filepath): QThread.msleep(300) # Reqd on some machines, give chance for write to complete # ^^ About to test this, may need more sophisticated solution with open(filepath) as file: last Line = list(file)[-1] dest Path = self._filemap[filepath]['dest file'] with open(dest Path, 'a') as out_file: # a= append out_file.writelines([last Line]) I don't know any Windows specific function.
If you only need it to work under Windows the 2nd example seems to be exactly what you want (if you exchange the path of the directory with the one of the file you want to watch). @dopatraman Here is how you can do this on an interval ` import sys import time pub = Monkey() while True: try: time.sleep(1) pub.watch() except Keyboard Interrupt: print('\n Done') break except: print(f' Unhandled error: ') `from Py Qt4 import Qt Core @Qt Slot(str) def directory_changed(path): print('Directory Changed!!! serpentine.com/blog/2008/01/04/why-you-should-not-use-pyinotifyimport os import win32file import win32con path_to_watch = "." # look at the current directory file_to_watch = "test.txt" # look for changes to a file called def Process New Data( new Data ): print "Text added: %s"%new Data # Set up the bits we'll need for output ACTIONS = FILE_LIST_DIRECTORY = 0x0001 h Dir = win32file. FILE_NOTIFY_CHANGE_LAST_WRITE, None, None ) # For each change, check to see if it's updating the file we're interested in for action, file in results: full_filename = join (path_to_watch, file) #print file, (action, "Unknown") if file == file_to_watch: new Text = a.read() if new Text ! It will just keep returning an empty string in this case.
It's a pity Python doesn't have this facility built in as Py Qt is a huge dependency if all you're using is teh QFile System Watcher class. I wanted to point out that you'll need a QApplication instance for it to work, I added "app = Qt Gui. One that may not be the best way of doing it, but it sure is a short way.
QApplication(sys.argv)" right under the imports and then "app.exec_()" after the signal connections. ), but for unix user, you should use the "fcntl" system call. It's mostly the same code if you need to write it in C (same function names) import time import fcntl import os import signal FNAME = "/HOME/TOTO/FILETOWATCH" def handler(signum, frame): print "File %s modified" % (FNAME,) signal.signal(signal. Handy tool for restarting application when changes have been made to the source.
