如何在tkinter的PanedWindow中设置帧的默认大小？

Question

I am working on a simple tkinter gui- one panedwindow and two frames inside it. The resizing is working fine. The problem is that when I add the second frame to the same panedwindow, it takes up all the space as shown in the image. Is there a way to set a default size for the child frames in the panedwindow and still be able to resize them using sash? I tried setting height using paneconfigure but it doesn't help. Any pointers are welcome. I just want frame2 to have a smaller height than frame1 initially.

pw = tk.PanedWindow(root, orient="vertical", sashpad=1)
pw.pack(fill=tk.BOTH, expand=1)
frame1= tk.Frame(pw, bg="#CFD8DC")
frame2 = tk.Frame(pw, bg="#fafafa")
pw.add(frame1)
pw.add(frame2)

“ pw.add（frame1，height = 400）”这行对我不起作用，但是无论如何，我找到的解决方案与您使用“ pw.add（frame1，weight = 1）”和“ pw”的消息有关。 add（frame2，weight = 3）“行以给出平移帧的初始大小。
