pyqt5 hello world
Make a graphical interface with PyQt?
Graphical interfaces made with PyQt run on: Microsoft Windows, Apple Mac OS X and Linux. We will create a Hello World app with PyQt.
PyQt is available for both Python 2 (2.7.9 tested) and Python 3.
To install write:
With apt-get you can use:
The app we write will show the message “Hello World” in a graphical window. Import the PyQt5 module.
The program starts in the main part.
We initialize Qt and create an object of the type HelloWindow.
We call the show() method to display the window.
if __name__ == "__main__":
The HelloWindow class inherits from the class QMainWindow.
We call its super method to initialize the window.
Several class variables are set: size and window title.
We add widgets to the window, including a label widget (QLabel) which displays the message “Hello World”.
