TK Treeview列排序

Question

是否可以通过单击列对Tk树视图中的条目进行排序？令人惊讶的是，我找不到任何文档/教程。

Answer 1

patthoyts从中#tcl指出，TreeView
Tk演示程序具有排序功能。这是等效的Python：

def treeview_sort_column(tv, col, reverse):
    l = [(tv.set(k, col), k) for k in tv.get_children('')]
    l.sort(reverse=reverse)

    # rearrange items in sorted positions
    for index, (val, k) in enumerate(l):
        tv.move(k, '', index)

    # reverse sort next time
    tv.heading(col, command=lambda: \
               treeview_sort_column(tv, col, not reverse))

[...]
columns = ('name', 'age')
treeview = ttk.TreeView(root, columns=columns, show='headings')
for col in columns:
    treeview.heading(col, text=col, command=lambda: \
                     treeview_sort_column(treeview, col, False))
[...]
