python-3.x - 带有网格的tkinter滚动条，它没有链接

问题描述

我正在学习 GUI，所以请理解下面我糟糕的代码。

我试图制作一个获取游戏角色信息的程序。因此，如果您按下“搜索”按钮，列表将显示在下方。但是......由于窗口大小，它只显示大约 11 个名称。所以我想为该区域放置一个滚动条，但我只是不知道如何链接滚动条来控制该区域。我的意思是，滚动条本身已经创建，它确实会滚动，但它不会滚动我想要的窗口。我一定是把它链接错了，但是……不确定。

下面是最小化的示例代码，但它仍然很长而且很粗糙。再次抱歉。如果有人能启发我，这对我的工作和我未来的工作都会有很大的帮助。

    output.insert(tk.END,"Text_Something")
    output.update()
    search_chr()

解决方案

首先，使用grid()放入frame_buttons画布不会影响scrollregion画布的效果。改为使用canvas.create_window()。

其次，最好在绑定回调中绑定<Configure>事件frame_buttons并更新画布。scrollregion然后添加小部件frame_buttons将自动更新scrollregion.

另请注意，您已经创建了新的scrollbar并在执行时将其放在相同的位置search_chr()。最好在函数之外创建scrollbar唯一一次。
