如何将字典值插入到Tkinter Treeview中

标签: python tkinter treeview can-bus

我正在开发一个解码can bus错误消息的程序。这些消息被准确地读入字典,但是我在将它们显示在树视图中时遇到了麻烦。我已经阅读了插入方法并查找了无数的例子,但字典和树视图的混合使我感到困惑。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,但是为了可验证的例子,它是为了让我的背上有一个pylint。

替换这部分代码

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

用这个

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

您需要将treeview中的数据作为tuple插入,以便将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()
