I’ve found the answer, after some digging. In Windows 7, the taskbar is not for “Application Windows” per se, it’s for “Application User Models”. For example, if you have several different instances of your application running, and each instance has its own icon, then they will all be grouped under a single taskbar icon. Windows … Read more
From inside your QDialog/QWidget class, you should be able to do: file = str(QFileDialog.getExistingDirectory(self, “Select Directory”))
qmake-qt5 –version or qmake –version
I had the same exact problem as you. Try moving self.parse_triggered = QtCore.pyqtSignal() out of your constructor but inside your class declaration. So instead of it looking like this: class Worker(QtCore.QThread): def __init__(self, parent = None): super(Worker, self).__init__(parent) self.parse_triggered = QtCore.pyqtSignal() It should look like this: class Worker(QtCore.QThread): parse_triggered = QtCore.pyqtSignal() def __init__(self, parent = … Read more
Both toolkits are actively maintained, and by now more or less equal in features and quality. There are only few, rather unimportant differences. Still, I’d recommend PySide for Python 2. It has a more reasonable API, mainly it doesn’t expose Qt types, which have a direct equivalent in Python (e.g. QString, QList, etc.) or which … Read more
17.4. signal — Set handlers for asynchronous events Although Python signal handlers are called asynchronously as far as the Python user is concerned, they can only occur between the “atomic” instructions of the Python interpreter. This means that signals arriving during long calculations implemented purely in C (such as regular expression matches on large bodies … Read more
I found part of the issue wrt to closing. So when you are creating the self._window in the attach function and you close the MainWindow, that other window (thread) is sitting around still. So if you add a self._window = None in the __init__ function and add a __del__ function as below, that part is … Read more
Another way to use .ui in your code is: from PyQt4 import QtCore, QtGui, uic class MyWidget(QtGui.QWidget) … #somewhere in constructor: uic.loadUi(‘MyWidget.ui’, self) both approaches are good. Do not forget, that if you use Qt resource files (extremely useful) for icons and so on, you must compile it too: pyrcc4.exe -o ui/images_rc.py ui/images/images.qrc Note, when … Read more
I created a little example that shows 3 different and simple ways of dealing with threads. I hope it will help you find the right approach to your problem. import sys import time from PyQt5.QtCore import (QCoreApplication, QObject, QRunnable, QThread, QThreadPool, pyqtSignal) # Subclassing QThread # http://qt-project.org/doc/latest/qthread.html class AThread(QThread): def run(self): count = 0 while … Read more
Here are Windows wheel packages built by Chris Golke – Python Windows Binary packages – PyQt In the filenames cp27 means C-python version 2.7, cp35 means python 3.5, etc. Since Qt is a more complicated system with a compiled C++ codebase underlying the python interface it provides you, it can be more complex to build … Read more
