我会使用一个Toplevel()
窗口来构建我自己的客户错误框。
我认为ttk
在这里使用按钮是个好主意,结合框架和权重,我们可以让窗口看起来足够体面。
为了防止用户调整窗口大小,我还必须设置一种方法来切换详细信息文本框。使用跟踪变量并使用易于设置的 if/else 语句。
最后,我们可以禁用文本框.config(state="disabled")
import tkinter as tk
import tkinter.ttk as ttk
import traceback
class MyApp(tk.Tk):
def __init__(self):
super().__init__()
tk.Button(self, text='test error', command=self.run_bad_math).pack()
@staticmethod
def run_bad_math():
try:
1/0
except Exception as error:
title = 'Traceback Error'
message = "An error has occurred: '{}'.".format(error)
detail = traceback.format_exc()
TopErrorWindow(title, message, detail)
class TopErrorWindow(tk.Toplevel):
def __init__(self, title, message, detail):
tk.Toplevel.__init__(self)
self.details_expanded = False
self.title(title)
self.geometry('350x75')
self.minsize(350, 75)
self.maxsize(425, 250)
self.rowconfigure(0, weight=0)
self.rowconfigure(1, weight=1)
self.columnconfigure(0, weight=1)
button_frame = tk.Frame(self)
button_frame.grid(row=0, column=0, sticky='nsew')
button_frame.columnconfigure(0, weight=1)
button_frame.columnconfigure(1, weight=1)
text_frame = tk.Frame(self)
text_frame.grid(row=1, column=0, padx=(7, 7), pady=(7, 7), sticky='nsew')
text_frame.rowconfigure(0, weight=1)
text_frame.columnconfigure(0, weight=1)
ttk.Label(button_frame, text=message).grid(row=0, column=0, columnspan=2, pady=(7, 7))
ttk.Button(button_frame, text='OK', command=self.destroy).grid(row=1, column=0, sticky='e')
ttk.Button(button_frame, text='Details', command=self.toggle_details).grid(row=1, column=1, sticky='w')
self.textbox = tk.Text(text_frame, height=6)
self.textbox.insert('1.0', detail)
self.textbox.config(state='disabled')
self.scrollb = tk.Scrollbar(text_frame, command=self.textbox.yview)
self.textbox.config(yscrollcommand=self.scrollb.set)
def toggle_details(self):
if self.details_expanded:
self.textbox.grid_forget()
self.scrollb.grid_forget()
self.geometry('350x75')
self.details_expanded = False
else:
self.textbox.grid(row=0, column=0, sticky='nsew')
self.scrollb.grid(row=0, column=1, sticky='nsew')
self.geometry('350x160')
self.details_expanded = True
if __name__ == '__main__':
App = MyApp().mainloop()
结果:


现在调整大小:D

更新:
回应您的以下陈述:
如果没有先初始化 Tk 实例,则不会显示错误窗口。
如果我们将类设置为它自己的Tk()
实例,它可以用作独立的错误弹出窗口。我还添加了一些对齐更改和一些调整大小的控件,以使此类更符合您在评论中提到的标准错误消息。
请参见下面的代码。
import tkinter as tk
import tkinter.ttk as ttk
class TopErrorWindow(tk.Tk):

super().__init__()
self.details_expanded = False
self.title(title)

self.minsize(350, 75)
self.maxsize(425, 250)
self.resizable(False, False)
self.rowconfigure(0, weight=0)
self.rowconfigure(1, weight=1)
self.columnconfigure(0, weight=1)
button_frame = tk.Frame(self)
button_frame.grid(row=0, column=0, sticky='nsew')
button_frame.columnconfigure(0, weight=1)
button_frame.columnconfigure(1, weight=1)
text_frame = tk.Frame(self)

ttk.Button(button_frame, text='Details',
command=self.toggle_details).grid(row=1, column=2, padx=(7, 7), sticky='e')

self.textbox.insert('1.0', detail)
self.textbox.config(state='disabled')
self.scrollb = tk.Scrollbar(text_frame, command=self.textbox.yview)
self.textbox.config(yscrollcommand=self.scrollb.set)
self.mainloop()
def toggle_details(self):
if self.details_expanded:
self.textbox.grid_forget()
self.scrollb.grid_forget()
self.resizable(False, False)
self.geometry('350x75')
self.details_expanded = False
else:

self.scrollb.grid(row=0, column=1, sticky='nsew')
self.resizable(True, True)
self.geometry('350x160')
self.details_expanded = True
结果:


您也可以使用带有所需错误图像类型的画布添加图像。
