Tkinter更改多个帧上的窗口大小

Question

那么，当使用类创建多个框架时，如何更改通用窗口大小
比如这里。我必须创建一个画布吗？我对这一切都不太确定，对国际米兰来说还是个新手。

try:
import tkinter as tk                
from tkinter import font as tkfont  
class SampleApp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
self.title_font = tkfont.Font(family='Helvetica', size=18, weight="bold", slant="italic")
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (StartPage, PageOne, PageTwo):
page_name = F.__name__
frame = F(parent=container, controller=self)
self.frames[page_name] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame("StartPage")
def show_frame(self, page_name):
frame = self.frames[page_name]
frame.tkraise()

class StartPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="This is the start page", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
button1 = tk.Button(self, text="Go to Page One",
command=lambda: controller.show_frame("PageOne"))
button2 = tk.Button(self, text="Go to Page Two",
command=lambda: controller.show_frame("PageTwo"))
button1.pack()
button2.pack()

class PageOne(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="This is page 1", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
button = tk.Button(self, text="Go to the start page",
command=lambda: controller.show_frame("StartPage"))
button.pack()

if __name__ == "__main__":
app = SampleApp()
app.mainloop()

我已经研究了多窗口问题的几种不同答案，但都没有创建自定义窗口大小。

Answer 1

不确定你想做什么，但试试这个：

self.geometry(f'{self.length}x{self.height}+{self.x}+{self.y}')

它允许您随时在代码中修改应用程序的几何图形。

self.resizable(width=True, height=True)

这允许用户手动调整应用程序的大小。
