I can give you an example of why such a thing: when you inherited a project and the original developer didn’t place the ui files in the repository (only left there the generated by pyuic4). True, that is a very particular example and that’s also my reason why I’m trying to find something (is not … Read more
Ref: http://doc.qt.io/qt-5/qscreen.html#grabWindow You say you require a screenshot of a window, therefore screenshot = screen.grabWindow(0, 0, 0, 100, 100) is not the appropriate call here, since it captures the entire screen, cropped according to the final 4 parameters. (the 100 parameters are width and height). screenshot = screen.grabWindow( widget.winId() ) captures the widget window. However, … Read more
I figured it out. Here’s what I ended up with in case it can help someone else. #!/usr/bin/python # -*- coding: latin-1 -*- import sys import base64 from PyQt4.QtGui import * from PyQt4.QtCore import * from PyQt4.QtWebKit import * from PyQt4 import QtNetwork class Render(QWebPage): def __init__(self, url): self.app = QApplication(sys.argv) username=”username” password = ‘password’ … Read more
First, it’s a bad idea to directly edit the code created with QtDesigner. You may have seen the line # WARNING! All changes made in this file will be lost! at the top of the document. For such a simple widget, you’re better off with manual coding. Secondly, take a closer look at what the … Read more
When first trying pyqt4 and pyqt5 and the pycharm IDE I had many problems with imports. (although the imports had no prob running from IDLE) Eventually after much stuffing around, uninstalling and reinstalling, (including dependencies) the imports sorted themselves out. Did you install pyqt5 using an installer from the pyqt website? You must. Qt designer … Read more
You should have a file called resource.qrc, this must be converted to .py, this or you can do it by executing: pyrcc5 resource.qrc -o resource_rc.py
The code you’re using as an example seem to work fine and looks quite clean. According to your comment your list widget is not getting initialized; this should be the root cause of your issue. I’ve simplified your code a bit a tried it on my Ubuntu 10.04LTS and it worked fine. My code is … Read more
Right, the PyQT packages are not using distutils / setup.py for it’s installation, so they can’t be installed with easy_install or pip. You need to download and install it manually. That also means you should not put it in your requires metadata, as easy_install and pip then will try to install it and fail. I … Read more
Modify your center method to be as follows: def center(self): frameGm = self.frameGeometry() screen = QtGui.QApplication.desktop().screenNumber(QtGui.QApplication.desktop().cursor().pos()) centerPoint = QtGui.QApplication.desktop().screenGeometry(screen).center() frameGm.moveCenter(centerPoint) self.move(frameGm.topLeft()) This function is based on where the mouse point is located. It uses the screenNumber function to determine which screen the mouse is current active on. It then finds the screenGeometry of that monitor … Read more
Pyqtgraph only enables realtime plotting by being quick to draw new plot data. How to achieve realtime plotting is highly dependent on the details and control flow in your application. The most common ways are: Plot data within a loop that makes calls to QApplication.processEvents(). pw = pg.plot() while True: … pw.plot(x, y, clear=True) pg.QtGui.QApplication.processEvents() … Read more
