我们从Python开源项目中，提取了以下9个代码示例，用于说明如何使用tkinter.messagebox.askyesnocancel()。 def maybesave(self):
if self.get_saved():
return "yes"
message = "Do you want to save %s before closing?" % (
self.filename or "this untitled document")
confirm = tkMessageBox.askyesnocancel(
title="Save On Close",
message=message,
default=tkMessageBox.YES,
master=self.text)
if confirm:
reply = "yes"
self.save(None)
if not self.get_saved():
reply = "cancel"
elif confirm is None:
reply = "cancel"
else:
reply = "no"
self.text.focus_set()
return reply
def main():
