    @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.

      @JonB Okay, here is the code with the forums code tags ^^

      <class MainWindow(QMainWindow):
      def init(self, parent=None):
      super().init(parent)
      self.ui = Ui_MainWindow()
      self.ui.setupUi(self)

          self.room_instance = Room(None, None, None)
          self.data=self.room_instance.read_data_from_file("rooms.json")
      
          self.ui.settings.clicked.connect(self.showSettings)
          self.ui.panels.clicked.connect(self.showPanels)
          self.ui.legendButton.clicked.connect(self.legend_change_size)
      
          for child in self.ui.grid.findChildren(QPushButton):
              self.apply_drop_shadow(child)
      
          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
      
          # Apply the drop shadow effect to the button
          self.ui.legendButton.setGraphicsEffect(shadow)
          self.ui.legend.setMinimumWidth(286)
          self.ui.legendButton.setVisible(True)
          #self.apply_drop_shadow(self.ui.legendButton)
          self.ui.button_area.setGeometry(70, 0, 1800, 1080)
          self.setWindowTitle("Vital Alert")
          self.setWindowIcon(QIcon("logo.png"))
      
          self.populate_buttons()
          self.set_icons()
      
          self.showFullScreen()
      
      def apply_drop_shadow(self, widget):
          shadow = QGraphicsDropShadowEffect(blurRadius=5, xOffset=10, yOffset=10)
          widget.setGraphicsEffect(shadow)

                        @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 This works:

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

                          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.
