如何将字典值插入 Tkinter Treeview

Question

我正在开发一个程序来解码 CAN 总线错误消息。这些消息被准确地读入字典，但我很难让它们显示在树视图中。我已经阅读了插入方法并查找了无数示例，但字典和树视图的混合让我感到困惑。这是一个小测试程序，我在插入语句中做错了什么？

from tkinter import *
from collections import OrderedDict
from tkinter import filedialog, ttk

GuiWindow = Tk()

TestDict = OrderedDict()

TestDict["MsgID"] = 1
TestDict["OtherData"] = 2

Errortree = ttk.Treeview(
    GuiWindow,
    columns=('Message ID', 'Other Data'))
Errortree.heading('#0', text='Message ID')
Errortree.heading('#1', text='Other Data')
Errortree.column('#0', stretch=YES)
Errortree.column('#1', stretch=YES)


treeview = Errortree

def TreeInsert():
print(TestDict)

Errortree.insert("", 'end', TestDict['MsgID'], TestDict['OtherData'])

scanvar = BooleanVar()

scanbtn = Checkbutton(
    GuiWindow,
    text="scan",
    variable=scanvar,
    command=TreeInsert,
    indicatoron=0)

Errortree.grid(row=0, columnspan=5, sticky='nsew')

scanbtn.grid(row=1, column=0)

GuiWindow.geometry('{}x{}'.format(400, 300))
GuiWindow.mainloop()

我确实意识到我有一个双重导入，但为了可验证的示例，它是为了让我摆脱 pylint。

Answer 1

替换这部分代码

Errortree.insert("", 'end', TestDict['MsgID'], TestDict['OtherData'])

有了这个

Errortree.insert("", 'end', values=(TestDict['MsgID'], TestDict['OtherData']))

您需要将您的数据作为tuple 插入treeview，所以我将您的dic 值转换为tuple

Errortree.insert("", 'end', values=(TestDict['MsgID'], TestDict['OtherData']))

完整代码

from tkinter import *
from collections import OrderedDict
from tkinter import filedialog, ttk

GuiWindow = Tk()

TestDict = OrderedDict()

TestDict["MsgID"] = 1
TestDict["OtherData"] = 2

Errortree = ttk.Treeview(GuiWindow,columns=('Message ID', 'Other Data'),show="headings")
Errortree.heading('#1', text='Message ID')
Errortree.heading('#2', text='Other Data')
Errortree.column('#1', stretch=YES)
Errortree.column('#2', stretch=YES)




def TreeInsert():

    print(TestDict)

#Errortree.insert("", 'end', TestDict['MsgID'], TestDict['OtherData'])
Errortree.insert("", 'end', values=(TestDict['MsgID'], TestDict['OtherData']))

scanvar = BooleanVar()

scanbtn = Checkbutton( GuiWindow,text="scan",variable=scanvar,
command=TreeInsert,indicatoron=0)

Errortree.grid(row=0, columnspan=5, sticky='nsew')

scanbtn.grid(row=1, column=0)

GuiWindow.geometry('{}x{}'.format(400, 300))
GuiWindow.mainloop()
