Question

我一直到处寻找是否可以找到任何帮助并且没有到任何地方我的程序是一个简单的tkinter菜单，设置为屏幕左上角的默认位置，但是当我按X按钮时，它会将消息框加载到屏幕中央。

我如何做到这一点，以便将消息框捕捉到角落？

root = Tk()
root.geometry('%dx%d+%d+%d' % (300, 224, 0, 0))
root.resizable(0,0)
def exitroot():
    if tkMessageBox.askokcancel("Quit", "Are you sure you want to quit?"):
        with open(settings, 'wb') as csvfile:
            writedata = csv.writer(csvfile, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL)
            writedata.writerow([setpass])
            writedata.writerow([opcolour] + [bkcolour])
            writedata.writerow([menu_background_status] + [menu_internet_status])
        root.destroy()
root.protocol("WM_DELETE_WINDOW", exitroot)`

如果需要任何额外的代码，请告诉我，谢谢。

您将需要构建一个自定义Toplevel()窗口，然后告诉它重新定位到根窗口的角落。我们可以使用Toplevel()类和winfo()方法来实现。

import tkinter as tk
# import Tkinter as tk # for Python 2.X


class MessageWindow(tk.Toplevel):
    def __init__(self, title, message):
        super().__init__()
        self.details_expanded = False
        self.title(title)
        self.geometry("300x75+{}+{}".format(self.master.winfo_x(), self.master.winfo_y()))
        self.resizable(False, False)
        self.rowconfigure(0, weight=0)
        self.rowconfigure(1, weight=1)
        self.columnconfigure(0, weight=1)
        self.columnconfigure(1, weight=1)
        tk.Label(self, text=message).grid(row=0, column=0, columnspan=3, pady=(7, 7), padx=(7, 7), sticky="ew")
        tk.Button(self, text="OK", command=self.master.destroy).grid(row=1, column=1, sticky="e")
        tk.Button(self, text="Cancel", command=self.destroy).grid(row=1, column=2, padx=(7, 7), sticky="e")

root = tk.Tk()
root.geometry("300x224")
root.resizable(0, 0)

def yes_exit():
    print("do other stuff here then root.destroy")
    root.destroy()

def exit_root():
    MessageWindow("Quit", "Are you sure you want to quit?")

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

结果：

我个人将全部构建在一个继承自Tk()的类中，甚至使用ttk按钮制作按钮，并使用标签来引用位于::tk::icons::question的内置问题图像，如下所示：

import tkinter as tk
import tkinter.ttk as ttk
# import Tkinter as tk # for Python 2.X

class GUI(tk.Tk):
    def __init__(self):
        super().__init__()
        self.geometry("300x224")
        self.resizable(0, 0)
        self.protocol("WM_DELETE_WINDOW", self.exit_window)

    def yes_exit(self):
        print("do other stuff here then self.destroy")
        self.destroy()

    def exit_window(self):
        top = tk.Toplevel(self)
        top.details_expanded = False
        top.title("Quit")
        top.geometry("300x100+{}+{}".format(self.winfo_x(), self.winfo_y()))
        top.resizable(False, False)
        top.rowconfigure(0, weight=0)
        top.rowconfigure(1, weight=1)
        top.columnconfigure(0, weight=1)
        top.columnconfigure(1, weight=1)
        tk.Label(top, image="::tk::icons::question").grid(row=0, column=0, pady=(7, 0), padx=(7, 7), sticky="e")
        tk.Label(top, text="Are you sure you want to quit?").grid(row=0, column=1, columnspan=2, pady=(7, 7), sticky="w")
        ttk.Button(top, text="OK", command=self.yes_exit).grid(row=1, column=1, sticky="e")
        ttk.Button(top, text="Cancel", command=top.destroy).grid(row=1, column=2, padx=(7, 7), sticky="e")

if __name__ == "__main__":
    GUI().mainloop()

结果：
