python tkinter 使用(二)
本篇文章着重讲下tkinter中messagebox的使用。
1：提示框
def showinfo(event):messagebox.showinfo("这是个提示框","this is message content")
2：错误提示框
def showerror(event):messagebox.showerror("这是个错误提示框","this is message content")
3：警告提示框
def showwarning(event):messagebox.showwarning("这是个警告提示框","this is message content")
4：询问对话框
使用messagebox.askquestion方法 ，该方法的返回值是yes/no.
def askquestion(event):result = messagebox.askquestion("请听题：", "中国历史上第一个大一统的国家是秦朝吗？")print(result)if result == 'yes':print("回答正确")else:print("回答错误")
5：是/否对话框
askyesno的返回值是True/False
def askyesno(event):result = messagebox.askyesno("选择吧","这是个弹框吗？")print(result)if result:print("回答正确")else:print("回答错误")
6：重试取消对话框
askretrycancel 返回值是True/False
def askretrycancel(event):result = messagebox.askretrycancel("重试","确认选择？")print(result)
7：确认取消对话框
返回值是True/False
def askokcancel(event):result = messagebox.askokcancel("取消框","确认取消吗？")print(result)
8：是/否/取消 对话框
返回值是True/False/None
def askyesnocancel(event):result = messagebox.askyesnocancel("！！！","选择吧！")print(result)
最后附上代码:
