是否可以使用tkinter和python将表单放入笔记本小部件中?

是否可以使用tkinter和python将表单放入笔记本小部件中?,python,forms,tkinter,Python,Forms,Tkinter,我一直在尝试使用python在tkinter中设计表单,但不幸的是,我又被卡住了,但现在将表单放入我已有的笔记本中。我已经分别运行了它们,它们工作得很好,当我尝试将它们组合在一起时,问题就开始了 例如,如果我在“componentComb=ttk.Combobox(frameOne,width=“19”)”而不是frameOne中写入我想做的第一步(合并它们),我会出现如下错误: componentComb= ttk.Combobox(firstStep, width="19") NameEr

我一直在尝试使用python在tkinter中设计表单,但不幸的是,我又被卡住了,但现在将表单放入我已有的笔记本中。我已经分别运行了它们,它们工作得很好,当我尝试将它们组合在一起时,问题就开始了

例如,如果我在“componentComb=ttk.Combobox(frameOne,width=“19”)”而不是frameOne中写入我想做的第一步(合并它们),我会出现如下错误:

componentComb= ttk.Combobox(firstStep, width="19")
NameError:未定义名称“firstStep”

我不明白,我已经定义了,但可能是错的!!!你能帮我解决这个问题吗

下面是我一直在“战斗”的代码,希望你能帮助我

提前谢谢

firstStep
defocus
函数中的局部变量,您试图在全局范围内访问它

您必须在函数之外定义它,以便它在全局范围内具有意义。但是请注意,因为您是在函数中分配它,所以需要使用
global
关键字,这样它就不会认为您引入了同名的新局部变量

这应该起作用:

firstStep = None  #define the variable globally
def defocus(event):

    event.widget.master.focus_set()

    if __name__ == '__main__':
        global firstStep  # we want to reassign the global version of this variable
        firstStep = Tkinter.Label(notebook, text=" 1. Enter Main Details: ", font=("fixedsys", "16","bold italic"))
        firstStep.grid(row=2, columnspan=7, sticky='W', \
                 padx=5, pady=5, ipadx=5, ipady=5)

componentComb= ttk.Combobox(firstStep, width="19")

亲爱的twasbrillig,感谢您的回复。。。我完全按照你说的去做了,但是没有用,有没有别的办法解决这个问题?谢谢!它不起作用了到底是怎么回事?您是否收到相同的错误消息?实际上它什么都不做,只是停止运行,当我尝试运行代码时,什么都没有发生。。。然后,我必须强制退出python,因为它停止尝试运行。。。有什么想法吗?嗯,我只是用“名称错误:名称‘第一步’未定义”来解决这个问题。这听起来像是另一个问题;我建议把它作为一个单独的问题发布。很抱歉
