我正在尝试将变量tkinter
与全局代码共享,
我有一个tkinter
gui,我在其中插入数据并关闭class App:
def __init__(self, master):
self.username = None
self.frame1 = tk.LabelFrame (master, text="Instagram")
self.frame1.pack ()
self.dict = {'':[], 'Scienza': ['Nasa', '2', '3'],
'Moda': ['vladislavkirillov', 'barengo1', 'vittorio__badia'],
'Dunk Page': ['stupidpikachu', 'nascecresceignora', 'the_fucking_dank']}
self.categoria_pagina = tk.StringVar()
self.pagina_preimpostata = tk.StringVar()
self.username1 = tk.StringVar()
self.password = tk.StringVar()
self.pagina_tua = tk.StringVar()
self.commento1 = tk.StringVar()
Entry (self.frame1, textvariable=self.username1, bg="white").grid (column=1, row=2, sticky=tk.W)
Entry (self.frame1, textvariable=self.password, bg="white").grid (column=1, row=3, sticky=tk.W)
Entry (self.frame1, textvariable=self.pagina_tua, bg="white").grid (column=1, row=4, sticky=tk.W)
self.categoria_pagina.trace('w', self.updateoptions)
self.optionmenu_a = ttk.OptionMenu(self.frame1, self.categoria_pagina, *self.dict.keys())
self.categoria_pagina.set("Scienza")
self.optionmenu_a.grid(row = 7, column = 1)
self.optionmenu_b = ttk.OptionMenu(self.frame1, self.pagina_preimpostata, '')
self.optionmenu_b.grid(row = 8, column = 1)
self.variable_c = tk.StringVar ()
self.variable_d = tk.StringVar ()
def updateoptions(self, *args):
countries = self.dict[self.categoria_pagina.get()]
self.pagina_preimpostata.set(countries[0])
menu = self.optionmenu_b['menu']
menu.delete(0, 'end')
for country in countries:
menu.add_command(label=country, command=lambda country=country: self.pagina_preimpostata.set(country))
categoria = self.categoria_pagina.get()
pagina_preimpostata_stringa = self.pagina_preimpostata.get()
username= self.username1.get()
password= self.password.get()
pagina_tua=self.pagina_tua.get()
root = tk.Tk()
app = App(root)
root.mainloop()
print(app.username)
表单,我希望代码打印此数据,但是该代码不接受我输入的数据,并返回另一个值
这是代码:
tkinter
它返回值None代替我在document.getElementById("email").value = 'change@change.com' ;
document.getElementById("password").value = 'change1234' ;
gui中插入的值
答案 0 :(得分:0)
问题在于,当您在代码中执行以下操作
git ls-remote
Python在函数范围内创建一个局部变量,当函数结束时,该变量不再存在。因此,您有多个解决方案。
一种方法是在username= self.username1.get()
的{{1}}中定义username
__init__
在您的函数中使用
App
随后您可以使用self.username = None
另一种选择是使用全局变量(不推荐)
self.username = self.username1.get()
