[英]python pass variable tkinter
I'm new im Python, just started to learn about class and tkinter, so forgive me "messy" code. 我是Python的新手,刚刚开始学习类和tkinter,所以请原谅我“凌乱”的代码。 I'm trying to enter some string to field nr1, and after click a button, print this string in console and store this value for later: 我尝试在字段nr1中输入一些字符串,然后单击按钮后,在控制台中打印此字符串并将其存储为以后使用:
from tkinter import Tk, BOTH, RIGHT, RAISED, BOTTOM, TOP, X, StringVar
from tkinter.ttk import Frame, Button, Entry
class AD(Frame):
def __init__(self, parent):
Frame.__init__(self, parent, v=None, raw_input=None)
self.parent = parent
self.parent.geometry("250x150+300+300")
self.parent.title("Trolollo")
self.parent.resizable(False, False)
self.inp = None
self.v = StringVar()
self.raw_input = None
self.initUI()
def user_input(self):
global inp
a = self.raw_input(self.v.get())
inp = a
return inp
def initUI(self):
self.pack(fill=BOTH, expand=True)
frame = Frame(self, relief=RAISED, borderwidth=0)
frame.pack(fill=BOTH, expand=True)
self.entry1 = Entry(frame, textvariable=self.v)
self.entry1.pack(side=TOP, fill=X, expand=False, padx=2, pady=2)
self.entry1.focus_set()
rename_button = Button(frame, text="Dispaly text", command = self.user_input())
rename_button.pack(side=TOP, expand=False, padx=2, pady=2)
entry2 = Entry(frame)
entry2.pack(side=TOP, fill=X, expand=False, padx=2, pady=2)
quit_button = Button(self, text="Quit", command=self.quit)
quit_button.pack(side=RIGHT, padx=5, pady=5)
ok_button = Button(self, text="OK")
ok_button.pack(side=RIGHT, padx=5, pady=5)
def main():
root = Tk()
app = AD(root)
root.mainloop()
if __name__ == '__main__':
main()
After executing code, i get: TypeError: 'NoneType' object is not callable 执行代码后,我得到:TypeError:'NoneType'对象不可调用
Any help would me appreciated 任何帮助,我将不胜感激
