Python 使用类时,如何获取tkinter中项目的值?
我想学一点tkinter。我在Youtube上看了几本指南,觉得自己对基础知识有很好的理解。但是,现在我正在尝试编写一个脚本,它可以作为快速日志使用,并且在从entry/text/optionmenu获取文本时遇到了问题 如果我在类之外设置gui,我只需做一个变量.get(),一切都很简单。但是当我在一个类中有我的gui tkinter东西时,我会得到一个未定义的异常 这是我的密码。问题在于def saveButtonCommand(self): 如何获取noteText和officeOption/Var的值Python 使用类时,如何获取tkinter中项目的值?,python,python-3.x,tkinter,Python,Python 3.x,Tkinter,我想学一点tkinter。我在Youtube上看了几本指南,觉得自己对基础知识有很好的理解。但是,现在我正在尝试编写一个脚本,它可以作为快速日志使用,并且在从entry/text/optionmenu获取文本时遇到了问题 如果我在类之外设置gui,我只需做一个变量.get(),一切都很简单。但是当我在一个类中有我的gui tkinter东西时,我会得到一个未定义的异常 这是我的密码。问题在于def saveButtonCommand(self): 如何获取noteText和officeOptio

我修正了它,你应该用self.“variable name”来声明一个可访问的属性

非常感谢。我尝试了将self添加到saveButtonCommand函数的各种组合,但我不认为会将self添加到变量本身。森林穿过树林。
