[FIXED] How to make a window you can't exit with any python module?

Issue

I'm trying to make a classroom manager that can allow teachers to control the students' device during lesson.(Temporarily displaying a window to 'lock' the screen of the student when the teacher is talking) I need to make a window that will automatically open in fullscreen when the teacher presses a button. However, making a window students can't exit was what I have been truggling with. I cantry to use pygame.set_mode(... pygame.FULLSCREEN) But the user can overide by Alt-F4 or Ctr-Alt-del

Solution

Ok, so I found something equivalent to what I'm trying to achieve: in pygame just override the quit event by doing nothing! so replace

for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                exit()

with

for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pass

which does nothing when quit occurs. In PyQt:

class MainWindow(QWidget): # or QMainWindow
    ...

    def closeEvent(self, event):
        # do stuff
        if can_exit:
            event.accept() # let the window close
        else:
            event.ignore()

And in Tkinter change:

import Tkinter as tk
import tkMessageBox as messagebox
root = tk.Tk()

def on_closing():
    if messagebox.askokcancel("Quit", "Do you want to quit?"):
        root.destroy()

root.protocol("WM_DELETE_WINDOW", on_closing)
root.mainloop()

To:

import Tkinter as tk
import tkMessageBox as messagebox
root = tk.Tk()

def on_closing():
    pass

root.protocol("WM_DELETE_WINDOW", on_closing)
root.mainloop()

I may have also forgotten to mention that the targeted audiences have managed devices with a policy enabled not allowing students to use task managers.
