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)
