有没有办法动态添加多个条目并从中获取值？
如下例所示，如果我单击“显示数据”按钮，则所有数据都会显示在不同的条目中。现在，如果我更改任何条目中的数据，如何获取更新的数据并将其保存到 Values 数组中？
from tkinter import * from tkinter import ttk class Root(Tk): def __init__(self): super(Root, self).__init__() self.createMultipleEntries() def createMultipleEntries(self): self.values = [ ["Full Name", "Email", "Phone", "Street Address", "Job Title"], ["Alex Blackater", "ablackater0@wordpress.org", "507-340-8136", "81604 Moose Park", "Senior Financial Analyst"], ["Alvy Chartres", "achartres1@linkedin.com", "926-801-1685", "4 Sundown Place", "Executive Secretary"], ["Juieta Train", "jtrain2@ucoz.com", "861-881-9312", "953 Hintze Circle", "Professor"], ["Basil Effemy", "beffemy3@liveinternet.ru", "156-293-8817", "115 Brentwood Trail", "Research Associate"], ["Asher MacAllister", "amacallister4@t-online.de", "263-605-8166", "8672 Stoughton Road", "Software Engineer II"] ] self.label_frame = ttk.LabelFrame(self) self.label_frame.pack() self.button_show = ttk.Button(self.label_frame, text="Show Data", command=self.onShowButtonClick) self.button_show.grid(row=0, column=0) self.button_update = ttk.Button(self.label_frame, text="Update Data", command=self.onUpdateButtonClick) self.button_update.grid(row=0, column=1) def onShowButtonClick(self): self.values_length = len(self.values) for i in range(1, self.values_length): entry_full_name = ttk.Entry(self.label_frame) entry_full_name.grid(row=i, column=0) entry_full_name.insert(0, self.values[i][0]) entry_email = ttk.Entry(self.label_frame) entry_email.grid(row=i, column=1) entry_email.insert(0, self.values[i][1]) entry_phone = ttk.Entry(self.label_frame) entry_phone.grid(row=i, column=2) entry_phone.insert(0, self.values[i][2]) entry_street_address = ttk.Entry(self.label_frame) entry_street_address.grid(row=i, column=3) entry_street_address.insert(0, self.values[i][3]) entry_job_title = ttk.Entry(self.label_frame) entry_job_title.grid(row=i, column=4) entry_job_title.insert(0, self.values[i][4]) def onUpdateButtonClick(self): pass def main(): root = Root() root.mainloop() if __name__ == '__main__': main()
有什么方法可以动态设置下面的内容吗？
entery_variable = StringVar() entry_ = ttk.Entry(self.label_frame, textvariable=entery_variable) entry_.grid(row=i, column=0) print(entry_variable.get())
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，以便我可以通过其二维索引 (i,j) 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。以下是代码。
from tkinter import * from tkinter import ttk class Root(Tk): def __init__(self): super(Root, self).__init__() self.createMultipleEntries() def createMultipleEntries(self): self.values = [ ["Full Name", "Email", "Phone", "Street Address", "Job Title"], ["Alex Blackater", "ablackater0@wordpress.org", "507-340-8136", "81604 Moose Park", "Senior Financial Analyst"], ["Alvy Chartres", "achartres1@linkedin.com", "926-801-1685", "4 Sundown Place", "Executive Secretary"], ["Juieta Train", "jtrain2@ucoz.com", "861-881-9312", "953 Hintze Circle", "Professor"], ["Basil Effemy", "beffemy3@liveinternet.ru", "156-293-8817", "115 Brentwood Trail", "Research Associate"], ["Asher MacAllister", "amacallister4@t-online.de", "263-605-8166", "8672 Stoughton Road", "Software Engineer II"] ] self.label_frame = ttk.LabelFrame(self) self.label_frame.pack() self.button_show = ttk.Button(self.label_frame, text="Show Data", command=self.onShowButtonClick) self.button_show.grid(row=0, column=0) self.button_update = ttk.Button(self.label_frame, text="Update Data", command=self.onUpdateButtonClick) self.button_update.grid(row=0, column=1) self.entryList = [] def onShowButtonClick(self): self.values_length = len(self.values) for i in range(1, self.values_length): entry_full_name = ttk.Entry(self.label_frame) entry_full_name.grid(row=i, column=0) entry_full_name.insert(0, self.values[i][0]) entry_email = ttk.Entry(self.label_frame) entry_email.grid(row=i, column=1) entry_email.insert(0, self.values[i][1]) entry_phone = ttk.Entry(self.label_frame) entry_phone.grid(row=i, column=2) entry_phone.insert(0, self.values[i][2]) entry_street_address = ttk.Entry(self.label_frame) entry_street_address.grid(row=i, column=3) entry_street_address.insert(0, self.values[i][3]) entry_job_title = ttk.Entry(self.label_frame) entry_job_title.grid(row=i, column=4) entry_job_title.insert(0, self.values[i][4]) self.entryList.append([entry_full_name, entry_email, entry_phone, entry_street_address, entry_job_title]) def onUpdateButtonClick(self): for i in range(1, len(self.values)): for j in range(len(self.values[0])): self.values[i][j] = self.entryList[i-1][j].get() # print(self.values) def main(): root = Root() root.mainloop() if __name__ == '__main__': main()
PS：我真的很想知道我所做的是否有点过头了！
