Python：Tkinter 框架出现/消失并且不显示子部件

Question

我正在制作一个游戏来测试我的技能，我创建了一个框架，该框架应该显示更多包含带有文本和图像的标签的框架。由于某种原因，主框架自行出现和消失，有时在屏幕上停留几秒钟，有时闪烁。框架内似乎没有出现任何小部件。

我添加了一些调试打印，似乎所有图像都已正确加载。程序不会停止，它会继续工作，但是，正如我所说，那一帧似乎闪烁并消失了。

这里是被调用以显示有问题的框架的函数的代码：

def show_party():
    global root, screenw, button_set, collection_page, selected_party_member

    try:
        screenw["PARTY_GRID"].destroy()
        del screenw["PARTY_GRID"]
    except: pass

    screenw["PARTY_GRID"] = Frame(
        root,
        bg = "#050505",
        width = 450,
        height = 128 * 6,
    )
    screenw["PARTY_GRID"].place(x = 100, y = 150)

    n = 0

    for party_slot in player_account.party:
        n += 1
        screenw[f"PARTY_FRAME_NO{n}"] = Frame(
            screenw["PARTY_GRID"],
            bg = "#FFFFFF",
        )

        screenw[f"PARTY_FRAME_NO{n}"].grid(row = n, column = 0)

        print(f"PARTY SLOT NO. {n}: {party_slot}")

        if party_slot[0] != None:
            pokeicon = POKEMON_ICONS[party_slot[0].id]
        else:
            pokeicon = IMAGE_UNKNOWN

        print(f"POKEICON NO. {n}: {pokeicon}")

        screenw[f"PARTY_NO{n}_ICON"] = Button(
            screenw[f"PARTY_FRAME_NO{n}"],
            bg = "#050505",
            image = pokeicon,
            border = 0,
            borderwidth = 0,
        ) #

        print(f"ICON LOADED!")

        screenw[f"PARTY_NO{n}_ICON"].place(x = 0, y = 0)

        print(f"ICON PLACED!")

        if party_slot[0] != None:
            screenw[f"PARTY_NO{n}_NICKNAME"] = Label(
                screenw[f"PARTY_FRAME_NO{n}"],
                bg = "#050505",
                fg = "#FFFFFF",
                font = ("Minecraft", 15),
                text = f"{party_slot[0].nickname}",
            )

            screenw[f"PARTY_NO{n}_NICKNAME"].place(x = 132, y = 0)
            screenw[f"PARTY_NO{n}_LEVEL"] = Label(
                screenw[f"PARTY_FRAME_NO{n}"],
                bg = "#050505",
                fg = "#FFFFFF",
                font = ("Minecraft", 10),
                text = f"Level {party_slot[0].level}",
            )

            screenw[f"PARTY_NO{n}_LEVEL"].place(x = 132, y = 20)

我正在使用Python 3.10.11。

请注意，使用

.place()

将小部件放入框架中不会调整父框架的大小，因此默认情况下父框架的大小为 1x1（以像素为单位）。

您需要指定足够大的父框架的大小以查看所有子窗口小部件：

for party_slot in player_account.party:
    n += 1
    screenw[f"PARTY_FRAME_NO{n}"] = Frame(
        screenw["PARTY_GRID"],
        bg = "#FFFFFF",
        width = 200,   # adjust this value to the desired width
        height = 200,  # adjust this value to the desired height
    )
    ...

或者使用

.grid()

或

.pack()

来放置这些子部件。
