Hi all
I can't seem to be able to make QFileSYstemWatcher work with a file (to see if
it's contents change).
At the end of this mail you'll find a minimum example that doesn't worked.
I tried several connections with different syntaxes but nothing works.
The versions I have:
Linux Red Hat
PyQt 4.4.2
Qt 4.4.0
Python 2.5.2
Thanks for your help.
A minimum example is:
#!/usr/bin/env python
import sys
from PyQt4 import QtCore, QtGui
import codecs
import codecs
from os.path import isfile, exists
class StartQT4(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.watcher = QtCore.QFileSystemWatcher(self)
QtCore.QObject.connect(self.watcher,QtCore.SIGNAL("fileChanged(const
QString&)"), self.file_changed)
QtCore.QObject.connect(self.watcher,QtCore.SIGNAL("fileChanged(const
QString)"), self.file_changed)
QtCore.QObject.connect(self.watcher,QtCore.SIGNAL("fileChanged(QString)"),
self.file_changed)
QtCore.QObject.connect(self.watcher,QtCore.SIGNAL("fileChanged"),
self.file_changed)
self.filename = '/home/to96665/toto'
if not exists:
print "merde"
self.watcher.addPath(self.filename)
def file_changed(self, path):
response = False
# buttons texts
SAVE = 'Save As'
RELOAD = 'Reload File'
CANCEL = 'Cancel'
message = QtGui.QMessageBox(self)
message.setText('Open file have been changed !')
message.setWindowTitle('Notepad')
message.setIcon(QtGui.QMessageBox.Warning)
message.addButton(SAVE, QtGui.QMessageBox.AcceptRole)
message.addButton(RELOAD, QtGui.QMessageBox.DestructiveRole)
message.addButton(CANCEL, QtGui.QMessageBox.RejectRole)
message.setDetailedText('The file "' + str(path) + '" have been
changed or removed by other application. What do you want to do ?')
message.exec_()
response = message.clickedButton().text()
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
myapp = StartQT4()
myapp.show()
sys.exit(app.exec_())
