    @poppypelt12 Please use code tags properly, especially when posting Python code where indentation is part of the syntax!

    @jsulm Sorry, I am a beginner haha :) i copied the code and pasted it but my program is more complex but this is the relevant part. Did i do something wrong with how i wrote the drop shadow or did i leave out a library? :(

      We are just asking you: when you paste code blocks, please enclose them in the forum's Code tags (the </> button). This will post all the code literally, including spacing, which is so vital in Python.

                          @poppypelt12 You were asked to write MINIMAL script. You did not.
                          Here, I did it for you:

                          from PySide6.QtWidgets import QApplication, QMainWindow, QPushButton, QGraphicsDropShadowEffect

                              def __init__(self, parent=None):
                                  super().__init__(parent)
                          
                                  shadow = QGraphicsDropShadowEffect()
                                  shadow.setBlurRadius(10)  # Adjust the blur radius as needed
                                  shadow.setXOffset(5)      # Adjust the X offset as needed
                                  shadow.setYOffset(5)      # Adjust the Y offset as needed
                          
                                  self.button = QPushButton(self)
                                  self.button.setGraphicsEffect(shadow)
                          
                          if __name__ == '__main__':
                              app = QApplication()

                              mainWindow.show()
                          
                              app.exec()
                          

                          And no, I don't see any drop shadow.

                            Do you know why? Hint: think about life time of "shadow" in the previous code.

                              @poppypelt12 You were asked to write MINIMAL script. You did not.
                              Here, I did it for you:

                              import sys
                              
                              from PySide6.QtWidgets import QApplication, QMainWindow, QPushButton, QGraphicsDropShadowEffect
                              
                              class MainWindow(QMainWindow):
                                  def __init__(self, parent=None):
                                      super().__init__(parent)
                              
                                      shadow = QGraphicsDropShadowEffect()
                                      shadow.setBlurRadius(10)  # Adjust the blur radius as needed
                                      shadow.setXOffset(5)      # Adjust the X offset as needed
                                      shadow.setYOffset(5)      # Adjust the Y offset as needed
                              
                                      self.button = QPushButton(self)
                                      self.button.setGraphicsEffect(shadow)
                              
                              if __name__ == '__main__':
                                  app = QApplication()
                              
                                  mainWindow = MainWindow()
                                  mainWindow.show()
                              
                                  app.exec()
                              

                              And no, I don't see any drop shadow.

                                    @poppypelt12 It is common mistake to declare a local variable which is destroyed as soon as it goes out of scope. Just be careful when declaring variables and think about scope and life time of objects.
