是否可以动态缩放 tkinter 窗口？

Question

对于我目前的 Python 项目，我通常在大学里使用 x 大小的显示器工作，但是当我想在家工作时，我的屏幕要小得多。我的大多数小部件目前都是根据高度和宽度参数调整大小的，所以当我在家工作时，我的 Tkinter 框架已经调整为适合我的工作监视器，对于主屏幕来说太大了，只有大约三分之二然后我的框架内容出现在屏幕上。我正在使用网格几何。

即使小部件没有高度参数也会出现问题，例如，小部件的行数太多，无法适应我的小屏幕。

是否可以缩放 Tkinter 帧，这样当我回家处理项目时，我的窗口会按比例缩小以适应较小的屏幕？

下面是一个示例类：

class home_page(tk.Frame):

    def __init__(self, parent, controller):
        
        tk.Frame.__init__(self, parent)
        self.controller = controller
        self.configure(background="white")
        h_title = tk.Label(self, text="Welcome to Fantasy Football!", fg="white", height=2, width=60, anchor="center", bg="#0ebf08", font=controller.title_font)
        h_squad_hub_lb = tk.Label(self, text="Squad Hub", fg="white", width=13, anchor="center", bg="#38003c", font=controller.title_font)
        squad_hub_text = "Selection headaches keeping you up\nat night? View your team below: "
        h_sh_text = tk.Label(self, text=squad_hub_text, bg="white", font=("Segoe UI", 13))
        h_view_team_bt = tk.Button(self, text="View Team", bg="#38003c", fg="white", command=lambda: controller.show_frame("pitch_view_team_page"))
        h_transfers_bt = tk.Button(self, text="Transfers", bg="#38003c", fg="white", command=lambda: controller.show_frame("pitch_view_transfers_page"))
        self.sh_img = PhotoImage(file = "Miscellaneous images/Squad Hub.png")
        h_sh_img = tk.Label(self, image=self.sh_img)

        self.n_img = PhotoImage(file = "Miscellaneous images/News.png")
        h_n_img = tk.Label(self, image=self.n_img)

        h_title.grid(row=0, column=0, columnspan=15, pady=(60,60))

作为一般经验法则，您应该只为您真正关心宽度和高度的小部件提供宽度和高度，例如文本小部件、列表框或树视图。您通常不需要为框架或整个窗口指定大小。

当您指定尺寸时，您应该选择必要的最小尺寸，然后使用pack、place 或grid 选项允许在窗口增大或缩小时调整小部件的大小。

如果没有关于您的特定问题的更多细节，我们将无法提供更具体的建议。
