[英]Using Tkinter and OOP to create transition frames in different classes (Python)
我正在為我的項目創建框架,到目前為止,當單擊按鈕時,我將它從主頁轉到主頁。 我面臨的問題是,當我嘗試從主頁到日志頁面的 go 時,我遇到了在 ZA2F2ED4F8EBC06CBB4C21A2 中調用 show_frame() function(位於 MainApplication)的問題。
我將如何 go 在 MainPage 中使用 arguments 以便我可以從主頁移動到日志頁面?
class MainApplication(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
# initialize frames
self.frames = {}
for F in (HomePage, MainPage, LogPage):
frame = F(container, self)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
# show home page frame first
self.show_frame(HomePage)
def show_frame(self, cont): # <-- FUNCTION HERE
frame = self.frames[cont]
frame.tkraise()
class HomePage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
continue_button = ttk.Button(self, text="Enter program", width=15,
command=lambda: controller.show_frame(MainPage)) # <-- works here
continue_button.pack()
class MainPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
def success_actions(self):
self.run_script_button["text"] = "View log"
self.run_script_button.configure(
command=lambda: controller.show_frame(LogPage)) # <-- want to use here
class LogPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
pass
class MainPage(tk.Frame):
def __init__(self, parent, controller):
self.controller = controller
tk.Frame.__init__(self, parent)
def success_actions(self):
self.run_script_button["text"] = "View log"
self.run_script_button.configure(
command=lambda: self.controller.show_frame(LogPage))
