Setting a transparent main window

2024/10/7 2:22:28

How to set main window background transparent on QT? Do I need an attribute or a style?
I've tried setting the opacity, but it didn't work for me.

app.setStyleSheet("QMainWindow {opacity:0}")

Answer

you must set new attribute for MainWindow object as below:

class Main(QtGui.QMainWindow):def __init__(self):self.setAttribute(Qt.WA_TranslucentBackground)
