python 如何使ttk.treeview的行可编辑?

有没有什么方法可以在可编辑的行中使用ttk Treeview?
我的意思是它应该更像一个表。例如,双击项目使#0列'可编辑'。
如果这是不可能的,任何方式允许鼠标选择的项目将是罚款。我还没有发现任何提到这在tkdocs或其他文件。

经过长时间的研究,我还没有发现这样的功能,所以我想有任何。TK是非常简单的接口,它允许程序员从基础构建“高级”功能。所以我想要的行为这样。

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)

    # get column position info
    x,y,width,height = self._tree.bbox(rowid, column)

    # y-axis offset
    # pady = height // 2
    pady = 0

    # place Entry popup properly         
    text = self._tree.item(rowid, 'text')
    self.entryPopup = EntryPopup(self._tree, rowid, text)
    self.entryPopup.place( x=0, y=y+pady, anchor=W, relwidth=1)

这是将ttk.Treeview组合为self._tree的类中的方法
EntryPopup是Entry的一个非常简单的子类:

class EntryPopup(Entry):

    def __init__(self, parent, iid, text, **kw):
        ''' If relwidth is set, then width is ignored '''
        super().__init__(parent, **kw)
        self.tv = parent
        self.iid = iid

        self.insert(0, text) 
        # self['state'] = 'readonly'
        # self['readonlybackground'] = 'white'
        # self['selectbackground'] = '#1BA1E2'
        self['exportselection'] = False

        self.focus_force()
        self.bind("<Return>", self.on_return)
        self.bind("<Control-a>", self.select_all)
        self.bind("<Escape>", lambda *ignore: self.destroy())

    def on_return(self, event):
        self.tv.item(self.iid, text=self.get())
        self.destroy()

    def select_all(self, *ignore):
        ''' Set selection on the whole text '''
        self.selection_range(0, 'end')

        # returns 'break' to interrupt default key-bindings
        return 'break'

您也可以弹出一个工具窗口,其中列出了可编辑的字段和条目,以更新值。本示例有一个三列的树视图,并且没有使用子类。
将您的双击绑定到以下内容:

def OnDoubleClick(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(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

以下是如何删除条目:

def DeleteCurrentEntry(treeView):
    curr = treeView.focus()

    if '' == curr: return

    treeView.delete(curr)

我已经尝试了@dakov解决方案,但它不适合我,因为我的treeView有多个列,还有一些原因。

class Tableview(ttk.Treeview):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        tv.bind("<Double-1>", lambda event: self.onDoubleClick(event))

    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
        try:  # in case there was no previous popup
            self.entryPopup.destroy()
        except AttributeError:
            pass

        # what row and column was clicked on
        rowid = self.identify_row(event.y)
        column = self.identify_column(event.x)

        # handle exception when header is double click
        if not rowid:
            return

        # get column position info
        x,y,width,height = self.bbox(rowid, column)

        # y-axis offset
        pady = height // 2

        # place Entry popup properly
        text = self.item(rowid, 'values')[int(column[1:])-1]
        self.entryPopup = EntryPopup(self, rowid, int(column[1:])-1, text)
        self.entryPopup.place(x=x, y=y+pady, width=width, height=height, anchor='w')

经过这么多的研究,而做我的项目得到了这个代码,它帮助了我很多。双击你要编辑的元素,作出所需的更改,然后单击“确定”按钮,我认为这正是你想要的

python #tkinter #treeview #editablerow

New rowEditable row

这只是为构造函数中设置的指定路径创建一个树。你可以将你的事件绑定到那个树上的项目。事件函数以一种可以以多种方式使用项目的方式保留。在这种情况下,双击它时,它会显示项目的名称。希望这对某些人有帮助。

你不应该这样做手动有准备使用包有这个功能和许多更如tkintertable它有一些疯狂的功能
还有pygubu-editable-treeview,如果你对pygubu感兴趣,
至于你不应该自己编写代码的原因,为了做一个好的treeview,你需要构建更多的功能,使你的gui更容易使用,但是这样的功能需要数百行代码来创建。(需要很长时间才能正确)除非你正在制作一个自定义的treeview小部件,否则不值得付出努力。

我已经调整了@DCOPTimDowd代码,使编辑单元格在视觉上更吸引人和更容易。
改进:

  • 可以分配不可编辑的列
  • 只需双击单元格即可编辑它。
  • 更有视觉吸引力。

我不知道如何使行可编辑,但要捕获单击行,您可以使用<<TreeviewSelect>>虚拟事件。这将通过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,但显示了调用的基本序列:

# 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
