添加多个条目并从中动态检索数据
Add multiple Entries and retrieve data from them dynamically
有没有办法动态添加多个条目并从中获取值？
如以下示例所示，如果我单击“显示数据”按钮，所有数据将显示在不同的条目中。现在，如果我更改任何条目中的数据，我如何才能获取更新后的数据并将它们保存到值数组中？

有没有办法动态设置如下所示的内容？

entry_.grid(row=i, column=0)
print(entry_variable.get())
提前致谢。 :)
我不清楚您希望它如何运行，但我有一个想法：将每个条目绑定到一个函数，该函数响应 Return 并在回调函数中进行处理。
def onShowButtonClick(self):
self.values_length = len(self.values)
for i in range(1, self.values_length):
# creating the entrys...
entry_full_name.bind('<Return>', self.change)
entry_email.bind('<Return>', self.change)
entry_phone.bind('<Return>', self.change)
entry_street_address.bind('<Return>', self.change)
entry_job_title.bind('<Return>', self.change)
def change(self, event):
print(event.widget.get())
如果您希望条目应该捕获每个条目的实际更改，您应该在创建时将它们关联到 StringVar()，然后使用 trace 挂钩对条目文本的任何更改。
关于更新您的值数组，这是我的想法。
我将所有条目存储在一个列表中，这样我就可以通过它的二维索引 (i,j) 来引用它。当您单击更新按钮时，它会从所有条目中获取值并更新值数组。这是代码。
