在另一個全屏顯示頂層 window window tkinter python

Question

我對 tkinter window 的全屏屬性有疑問。 主要的 window 具有全屏屬性，第二個必須顯示在主要的頂部而不會在點擊外部時迷路。 請問有什么幫助嗎？

# add the necessairy librairy
import tkinter as tk

def Region_windows2():
    #master is the second window with toplevel option
    master = tk.Toplevel(Mafenetre) #removed your mainframe class

    w = 300 # width for the Tk root
    h = 200 # height for the Tk root
    # get screen width and height
    ws = master.winfo_screenwidth() # width of the screen
    hs = master.winfo_screenheight() # height of the screen
    # calculate x and y coordinates for the Tk master window
    x = (ws/2) - (w/2)
    y = (hs/2) - (h/2)
    # set the dimensions of the screen 
    # and where it is placed
    master.geometry('%dx%d+%d+%d' % (w, h, x, y))
    # when open the second window i want it to be on toplevel; it means when i click outside the frame it won't get hide
    master.attributes("-topmost", True)
    master.title("password")

# here's the main window
Mafenetre = tk.Tk()
#set main window title
Mafenetre.title("GUI")
Mafenetre['bg']='white' # couleur de fond
# get screen width and height
wf1= Mafenetre.winfo_screenwidth()
hf1= Mafenetre.winfo_screenheight()
A = str(wf1)
B = str(hf1)
# set the dimensions of the screen 
# and where it is placed
Mafenetre.geometry(A+"x"+B)
Mafenetre.attributes('-fullscreen', True)
# add menubar to the main window
menubar = tk.Menu(Mafenetre, bg='#1f1b13', fg='white')
# menubar button to test the second window
menubar.add_command(label="tester", command=Region_windows2)
# add menubr to the main window
Mafenetre.config(menu=menubar)
Mafenetre.mainloop()

此問題取決於 window 管理器如何處理全屏 windows，因此，在某些情況下，只需使用master.attributes("-topmost", True)就足以將頂層保持在主 Z05B8C742702FBF2DEZFC13A 之上但是，就我而言（Linux、XFCE 桌面環境），它不起作用。 我發現的解決方法是在頂層失去焦點時重新調整焦點並綁定到<FocusOut> ：

master.bind('<FocusOut>', lambda ev: master.focus_force())

在Region_windows2()中。

請注意，此解決方法顯然會阻止在打開頂層時在主 window 中的Text或Entry小部件中寫入任何內容，但如果主 window 被“禁用”（例如在頂層使用.grab_set() ，這不是問題。
