有没有办法使用ttk Treeview和可编辑的行？
我的意思是它应该更像是一张桌子。例如，双击项目使＃0列'可编辑'。
如果无法做到这一点，任何允许鼠标选择项目的方法都可以。我在tkdocs或其他文件中没有发现任何提及。

经过长时间的研究，我没有找到这样的功能，所以我猜有没有。 Tk是一个非常简单的界面，它允许程序员从基础构建“高级”功能。所以我希望这样做。
def onDoubleClick(self, event):
''' Executed, when a row is double-clicked. Opens
read-only EntryPopup above the item's column, so it is possible
to select text '''
# close previous popups
self.destroyPopups()
# what row and column was clicked on
rowid = self._tree.identify_row(event.y)
column = self._tree.identify_column(event.x)
# clicked row parent id
parent = self._tree.parent(rowid)
# do nothing if item is top-level
if parent == '':
return
# get column position info
x,y,width,height = self._tree.bbox(rowid, column)
# y-axis offset
pady = height // 2
# place Entry popup properly
url = self._tree.item(rowid, 'text')
self.entryPopup = EntryPopup(self._tree, url)
self.entryPopup.place( x=0, y=y+pady, anchor=W, relwidth=1)
这是一个将ttk.Treeview组成self._tree
的类中的方法然后EntryPopup是一个非常简单的Entry子类：
class EntryPopup(Entry):
def __init__(self, parent, text, **kw):
''' If relwidth is set, then width is ignored '''
super().__init__(parent, **kw)
self.insert(0, text)
self['state'] = 'readonly'
self['readonlybackground'] = 'white'
self['selectbackground'] = '#1BA1E2'
self['exportselection'] = False
self.focus_force()
self.bind("<Control-a>", self.selectAll)
self.bind("<Escape>", lambda *ignore: self.destroy())
def selectAll(self, *ignore):
''' Set selection on the whole text '''
self.selection_range(0, 'end')
# returns 'break' to interrupt default key-bindings
return 'break'

您还可以弹出一个工具窗口，其中包含使用条目列出的可编辑字段来更新值。此示例具有包含三列的树视图，并且不使用子类。
双击双击：
def OnDoubleClick(self, treeView):
# First check if a blank space was selected
entryIndex = treeView.focus()
if '' == entryIndex: return
# Set up window
win = Toplevel()
win.title("Edit Entry")
win.attributes("-toolwindow", True)
####
# Set up the window's other attributes and geometry
####
# Grab the entry's values
for child in treeView.get_children():
if child == entryIndex:
values = treeView.item(child)["values"]
break
col1Lbl = Label(win, text = "Value 1: ")
col1Ent = Entry(win)
col1Ent.insert(0, values[0]) # Default is column 1's current value
col1Lbl.grid(row = 0, column = 0)
col1Ent.grid(row = 0, column = 1)
col2Lbl = Label(win, text = "Value 2: ")
col2Ent = Entry(win)
col2Ent.insert(0, values[1]) # Default is column 2's current value
col2Lbl.grid(row = 0, column = 2)
col2Ent.grid(row = 0, column = 3)
col3Lbl = Label(win, text = "Value 3: ")
col3Ent = Entry(win)
col3Ent.insert(0, values[2]) # Default is column 3's current value
col3Lbl.grid(row = 0, column = 4)
col3Ent.grid(row = 0, column = 5)
def UpdateThenDestroy():
if ConfirmEntry(treeView, col1Ent.get(), col2Ent.get(), col3Ent.get()):
win.destroy()
okButt = Button(win, text = "Ok")
okButt.bind("<Button-1>", lambda e: UpdateThenDestroy())
okButt.grid(row = 1, column = 4)
canButt = Button(win, text = "Cancel")
canButt.bind("<Button-1>", lambda c: win.destroy())
canButt.grid(row = 1, column = 5)
然后确认更改：
def ConfirmEntry(self, treeView, entry1, entry2, entry3):
####
# Whatever validation you need
####
# Grab the current index in the tree
currInd = treeView.index(treeView.focus())
# Remove it from the tree
DeleteCurrentEntry(treeView)
# Put it back in with the upated values
treeView.insert('', currInd, values = (entry1, entry2, entry3))
return True
以下是删除条目的方法：
def DeleteCurrentEntry(self, treeView):
curr = treeView.focus()
if '' == curr: return
treeView.delete(curr)

我不知道如何使行可编辑，但要捕获单击某行，您可以使用<<TreeviewSelect>>虚拟事件。这将使用bind()方法绑定到例程，然后使用selection()方法获取所选项目的ID。
这些是来自现有程序的片段，但显示了基本的调用序列：
# in Treeview setup routine
self.tview.tree.bind("<<TreeviewSelect>>", self.TableItemClick)
# in TableItemClick()
selitems = self.tview.tree.selection()
if selitems:
selitem = selitems[0]
text = self.tview.tree.item(selitem, "text") # get value in col #0

这仅用于为构造函数中设置的指定路径创建树。您可以将事件绑定到该树上的项目。保留事件功能的方式是可以以多种方式使用该项目。在这种情况下，双击时会显示项目的名称。希望这有助于某人。
