I am collecting usage stats for my applications which include how much each session lasts. However, I can't seem to be able to save this information because None Of the signals I tried yet actually succeeds to call my report_session function. This are the signals I have already tried: lastWindowClosed() aboutToQuit() destroyed() Ei...
I'm currently producing PDFs using python and PyQT. I'd like to change the "Producer" value of the PDF's document information, currently it is set to "Qt 4.6.2 (C) 2010 Nokia Corporation and/or its subsidiary(-ies)". I've looked through the QPrinter reference, and nothing obvious stuck out that I could set. How do I change the docum...
This is probably very basic, but it's giving me a headache, and I'm not sure what method to even approach it with, making the googling tough. If I have a class in a module that I'm importing with various prints throughout, how can I read the prints as they come so that I may output them to a PyQT text label? class Worker(QtCore.QThread...
I am developing an application that uses multiple threads to gather data from a variety of network devices. I'm using PyQT to display the collected data on a GUI. I am using regular python threads (from thread, threading) in my app (instead of QThread). In order to update the GUI on the different threads, I use a lock (thread.allocate_l...

Here's the code: class mouseoverEvent(QtCore.QObject): def __init__(self, parent): super(mouseoverEvent, self).__init__(parent) def eventFilter(self, object, event): if event.type() == QtCore.QEvent.MouseMove: print "mousemove...
When the menu of a QTabWidget grows beyond its width, the default behaviour is to turn the tab menu into a horizontaly scrollable list. What I'd prefer is to wrap the menu round so you now have two rows of tabs. This style is used on some Windows dialogs. I can't find any way to do this though. Is anyone aware of a trick or option to al...
I have a QWebView in my app which renders a html page stored in the app as a Qresource. This page, however requires meaty external Javascript libraries such as MathJax, which I would want to include as a resource due to its size. My problem is that it seems that QtWebkit does not cache these files as a regular browser would do, and eve...
I have a subclassed QFrame that generates a list of buttons when my project loads, and at times, I want to be able to completely destroy and rebuild "buttonGrid". Rather than add a button in the proper spot with the proper geometry settings etc. I figured it'd be easiest to destroy this and then call it again as it was originally one. ...
I have a programs that runs several threads (on a while loop until Ctrl C is pressed). The app also has a GUI that I developed in PyQt. However, I am facing the following problem: If I press Ctrl C on the console, and then close the GUI, the program exits fine. However, if I close the GUI first, the other threads won't stop and the prog...

Hi. I have a list of actions on a menu in PyQt, one for each different feed I want to display. So I have a Y that sets the active feed to Y, Z sets it to Z, etc. (For a webcomic reading program). I have each on the menu, and felt that an automated approach might be better; rather than typing out each time. Something like a function tha...

Hello all, I am hoping to use PyQt to produce an application that will display an equation entered by the user. I had considered matplotlib, but this seems like overkill as I would only be using it to render the latex. I need to use SymPy anyway, so I was hoping there would be a way to use it to do the rendering also, preferably produc...
I'm trying to capture the output of a windows program using Qt and Python. I'm starting the process with QProcess, but the problem is the output is being buffered. Unfortunately I don't have access to the source, and therefore can't flush the output. From my searching around, I found the program "Expect", but I don't know if there is...
