问题描述
我正在使用Kivy为我的密码管理器制作图形界面。 我已经做好登录页了。我不知道如何将密码登录名上载到其他文件中的其他类以解密其他密码？
class MainApp(MDApp):
def build(self):
self.theme_cls.theme_style = "Dark"
self.theme_cls.primary_palette = "BlueGray"
return Builder.load_file('libskvlogin_page.kv')
def logger(self):
try :
passwd = verif_password(self.root.ids.password.text)
passwd_bdd = passwd
if passwd == True :
self.get_running_app().stop()
import graphical_password
else :
print("NO")
except :
print("No passs")
MainApp().run()
我的导入Graphical_Password是此代码：
class MainApp(MDApp):
def build(self):
screen = Screen()
table = MDDataTable(
pos_hint = {'center_x' : 0.5, 'center_y' : 0.5},
size_hint = (0.9, 0.6),
check = True,
column_data =[
("F_name", dp(30)),
("Name", dp(30)),
("Mail", dp(30)),
("Phone", dp(30)),
],
row_data = [
("P1","P2","GAMIL","0658"),
("P3","P4","GAMIL","0658"),
]
)
self.theme_cls.theme_style = "Light"
self.theme_cls.primary_palette = "BlueGray"
screen.add_widget(table)
return screen
MainApp().run()
您知道如何将第一个页面中输入的密码输入到另一个页面中吗？
