如何使 Tkinter 列表框适合内容

2022-01-16 00:00:00 python tkinter listbox

问题描述

我正在使用下面的代码将字符串添加到列表框.当我运行代码并打开窗口时，由于窗口不够大，较长的字符串会被剪掉(见屏幕截图).我曾尝试使窗口可调整大小并添加滚动条，但我想知道是否有办法自动调整大小以适应内容.

I'm adding strings to a listbox using the code below. When I run the code and the window opens, the longer strings get clipped as the window is not large enough (see screenshot). I have tried making the window resizeable and adding scroll bars but I was wondering if there was a way to automatically size it to fit the content.

master = tk.Tk()
listbox = tk.Listbox(master, selectmode=tk.SINGLE)

games = ["Garry's Mod", "Mount and Blade: Warband", "Tekkit"]
for game in sorted(games):
    listbox.insert(tk.END, game)

button = tk.Button(master, text="Execute", command=execute)

listbox.pack()
button.pack()
tk.mainloop()

解决方案

重置列表框宽度对我有用.我使用了 Oblivion 的答案，发现宽度始终为零.

Resetting the listbox width worked for me. I used the Oblivion's answer and noticed that the width is always zero.

listbox = tk.Listbox(master, selectmode=tk.SINGLE)
listbox.config(width=0)

我还建议在重新加载列表内容后重置根窗口几何图形.否则，如果用户手动扩展窗口，窗口将停止适应其内容的大小.

I also recommend to reset the root window geometry after reloading a content of the list. Otherwise if user manually extends a window the window would stop accommodate size of its content.

root.winfo_toplevel().wm_geometry("")
