Python Tkinter Treeview 添加图像作为列值

Question

我正在尝试将图像添加到 TreeView 上每一行的第一列，但无论我做什么，总是以显示的对象名称“pyimage1”而不是实际图像结束。 As this image shows

我使用的代码是这样的。

    from tkinter import PhotoImage.
    self._img = PhotoImage(file="resources\information_picto.gif")
    self.tree.insert('', 'end', values= self._image,self.name, self.status, self.cores, self.turn, self.added_time)

我尝试过使用 png，结果相同，我知道我的图像对象已正确创建，因为在调试时我可以看到图像的属性，但我无法让它显示在 TreeView 上行。

编辑:

 def __init__(self, master, **kw):
    self.SortDir = True
    f = ttk.Frame(master)
    f.pack(fill=BOTH, expand=True)
    self.dataCols = ('Project Name', 'Status', 'Cores', 'Turn', 'Added date/time')
    self.tree = ttk.Treeview(columns=self.dataCols,
                             show='headings')
    self.tree.column("Project Name", anchor="center")

    self.tree.grid(in_=f, row=0, column=0, sticky=NSEW)
    f.rowconfigure(0, weight=1)
    f.columnconfigure(0, weight=1)
    style = ttk.Style(master)
    style.configure('Treeview', rowheight=38)

    self._img = PhotoImage(file="resources\information_picto.gif")  
    self.tree.insert('', 'end', text="#0's text", image=self._img,
                     value=("A's value", "B's value"))

我正在尝试上面的代码，它与你的非常相似，但我找不到我的错误，但是我看到“文本”或“图像”字段出现在行中，只是列表我作为“值(value)”传递的值(value)观，有什么想法吗？

您可以使用 w.insert 方法中的 image 参数显示图像。见下文。

from tkinter import PhotoImage.
self._img = PhotoImage(file="resources\information_picto.gif")
self.tree.insert('', 'end', text='Information_picto.gif', open=True, image=self._img, 
                 value=(self.name, self.status, self.cores, self.turn, self.added_time))

这是一个示例脚本，显示了 ttk.Treeview 小部件的基本设置以及如何将图像包含到小部件的 #0 列和第一行(标题下方)。

#!/usr/bin/python3
# -*- coding: utf-8 -*-

import tkinter as tk
import tkinter.ttk as ttk

class App(ttk.Frame):

    def __init__(self, parent=None, *args, **kwargs):
        ttk.Frame.__init__(self, parent)
        self.parent = parent

        # Create Treeview 
        self.tree = ttk.Treeview(self, column=('A','B'), selectmode='none', height=7)
        self.tree.grid(row=0, column=0, sticky='nsew')

        # Setup column heading
        self.tree.heading('#0', text=' Pic directory', anchor='center')
        self.tree.heading('#1', text=' A', anchor='center')
        self.tree.heading('#2', text=' B', anchor='center')
        # #0, #01, #02 denotes the 0, 1st, 2nd columns

        # Setup column
        self.tree.column('A', anchor='center', width=100)
        self.tree.column('B', anchor='center', width=100)

        # Insert image to #0 
        self._img = tk.PhotoImage(file="imagename.gif") #change to your file path
        self.tree.insert('', 'end', text="#0's text", image=self._img,
                         value=("A's value", "B's value"))


if __name__ == '__main__':
    root = tk.Tk()
    root.geometry('450x180+300+300')

    app = App(root)
    app.grid(row=0, column=0, sticky='nsew')

    root.rowconfigure(0, weight=1)
    root.columnconfigure(0, weight=1)

    root.mainloop()

回应您的编辑:请参阅脚本中的注释以获取解释。还建议您试验我提供给您的早期脚本，以帮助您更好地理解如何使用 Treeview 小部件。玩得开心。
