我想在主窗口上制作一个弹出窗口

【中文标题】我想在主窗口上制作一个弹出窗口

【英文标题】：I Want to make a Pop up window over main window

【问题描述】：

它应该表现得像当弹出窗口打开时我们不能使用主窗口，直到我们退出弹出窗口

我不使用 tkinter 消息框的原因是我无法自定义它

我想自定义并找到了一种方法，但问题是当弹出窗口打开时，我可以轻松单击主窗口按钮并打开多个弹出窗口，所以我希望在窗口弹出时禁用主窗口并获取弹窗关闭后恢复正常

我的代码是这样的

from tkinter import *
win = Tk()
win.title("Main Window")

def closing_try():
    close = Tk()
    close.title("Warning")
    close.geometry('200x100')
    close.overrideredirect(0)
    close.configure(bg='white')
    close.resizable(False, False)
    close.attributes("-topmost", True)
    close.eval('tk::PlaceWindow . center')

    def save_b_func():
        close.destroy()
        save_func()
        win.destroy()

    def dont_save_b_func():
        win.destroy()
        close.destroy()

    def cancel_b_func():
        close.destroy()

    
    ask_lbl = Label(close, text='''Do You Want to Save File
Before Exiting?''', bg='white', font=('consolas', 10, 'normal'))
    ask_lbl.place(x=10, y=5)
    save_b = Button(close, text='Save', font=('consolas', 10, 'normal'), command=save_b_func, bg='white').place(x=9, y=50)
    dont_save_b = Button(close, text="Don't Save", font=('consolas', 10, 'normal'), command=dont_save_b_func, bg='white').place(x=53, y=50)
    cancel_b = Button(close, text='Cancel', font=('consolas', 10, 'normal'), command=cancel_b_func, bg='white').place(x=139, y=50)

    close.mainloop()

button = Button(win, text='click me', command = closing_try).pack()

win.mainloop()

【参考方案1】：

如果你想让主窗口可见，你可以这样做：

win.grab_set() # show popup window
win.grab_release() # return to normal

或

master.withdraw() # hide main window
master.deiconify()# return main window

这里有一些示例代码，以便您了解它的工作原理：

from tkinter import *

win = Tk()

win.geometry("450x400")
new_win = Toplevel(win)
new_win.geometry("700x250")
new_win.title("NEW WINDOW")
new_win.withdraw()
Label(new_win, text="Example Label", font=('Helvetica 15 bold')).pack(pady=10)


def show_new():
    new_win.grab_set()
    new_win.deiconify()


def show_old():
    new_win.grab_release()
    new_win.withdraw()


def print_text():
    print("BUTTON IS PRESSED")


button = Button(win, text="Show",command= show_new)
button.pack(pady=50)
button_text = Button(win, text="print",command=print_text)
button_text.pack(pady=100)

button2 = Button(new_win, text="OK",command= show_old)
button2.pack(pady=50)

win.mainloop()
