I’m in a situation where I want to assert the identity of a PyQt5 signal. Specifically, I want to check whether the clicked signal from a given QPushButton object is identical to a signal that is stored in a variable named signal. The following snippet illustrates the situation:
I nearly finished my application, when the customer asked if I could implement some kind of login form on application startup.
I am using the given code, I want the user to enter text in the QLineEdit widget, press the Copy! button and see the inputted text replace the ‘N/A’ label. My questions is: following this procedure, how can I clear the text inputted in the QLineEdit widget with a simple mouse click?

This means: I run the program, no window shows up, just a tray icon (I’ve got a png file) shows up in the systray and when I right-click on it a menu appears with some options (and when I click on an option, a function is run).
Is that possible? I don’t need any window at all…

I’d like to Change the color of the axis, as well as ticks and value-labels for a plot I did using matplotlib and PyQt.
I have tried adding the pdf.js viewer files in my project and it works in browsers like Chrome, Mozilla, Safari, etc, but it’s not loading some pages in node-webkit and PyQt webkit.
I need a double inheritance for a class.
I tried several syntaxes but I don’t understand the concept of metaclass.
Suppose I have an object and want one of its methods to be executed when a PyQt signal is emitted. And suppose I want it to do so with a parameter that is not passed by the signal. So I create a lambda as the signal’s slot:
