    @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 Did you actually check whether self.ui.grid.findChildren(QPushButton) returned anything?

            @jsulm I dont know, but I tried doing it in another project on a regular single button, and it didn't work in there either, does it work for you?

              @poppypelt12 Well, without ui_form I can't run your script.

                  @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 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.
