Tkinter:如何将文本小部件中输入的文本保存到新窗口?

标签: python tkinter save text-widget

嗨,我是Tkinter编程的新手。我写了这个程序,正在制作中。我创建了一个名为IngredientAdder()的类,并在方法def steps_box下的该类中,我有一个变量self.entry2,它调用Text Widget。当我运行该程序时,文本框工作正常。但是,根据我的方法def save_recipie,当我按下words.get('1.0', 'end')方法中的按钮时,我写了它以便将init.gui打印到终端窗口中(words.get对应于用户输入的文本)在名为self.entry2的文本框中。但是,当我运行程序并在文本框中输入文本并按下保存按钮时,我的终端窗口中没有任何内容。如何修改我的代码,以便用户在文本框中输入的文本打印到我的终端窗口?帮助

如果您可以在代码中添加注释,那将非常有用!感谢。

代码

def steps_box(self):
    self.entry2 = Tkinter.Text(self.frame2,width=40,height=33,font="helvetica 12",padx=5,pady=5).pack(anchor=Tkinter.NW,side=Tkinter.RIGHT)

self.entry2中注册无。你应该把

def steps_box(self):
    self.entry2 = Tkinter.Text(self.frame2, width=40, height=33, font="helvetica 12", padx=5, pady=5)
    self.entry2.pack(anchor=Tkinter.NW, side=Tkinter.RIGHT)

但是,您没有将self.entry2注册到self.text_entries,因为您没有调用方法text_box
