我正在創建一個代碼編輯器，并且想要一個側欄，其中包含用戶打開的檔案夾檔案以及如何通過從文本小部件中的 Treeview 中選擇檔案來打開檔案
我已經為檔案創建了一面，但我仍然遇到了一些問題，即如何在文本小部件中從樹視圖打開檔案
這是我的代碼
from tkinter import*
from tkinter import ttk
import os
from tkinter.filedialog import askdirectory
def Open():
for i in tree.get_children():
tree.delete(i)
path = askdirectory()
abspath = os.path.abspath(path)
root_node = tree.insert('', 'end', text=abspath, open=True)
process_directory(root_node,abspath)
def process_directory( parent, path):
for p in os.listdir(path):
abspath = os.path.join(path, p)
isdir = os.path.isdir(abspath)
oid = tree.insert(parent, 'end', text=p, open=False)
if isdir:
process_directory(oid, abspath)
def Open_file_from_list_box(value):
global file
file = tree.selection()
filepath = os.path.join(value,file)
root.title(filepath " Code Editor")
editor.delete(1.0,END)
with open(filepath,"r") as f:
editor.insert(1.0,f.read())
root = Tk()
root.geometry("1550x850 0 0")
Button(root,text="Open",command=Open).pack()
frame = Frame(root)
tree = ttk.Treeview(frame)
tree.pack(expand=True,fill=Y)
path = "."
tree.heading('#0', text=path, anchor='w')
abspath = os.path.abspath(path)
root_node = tree.insert('', 'end', text=abspath, open=True)
process_directory(root_node, abspath)
frame.pack(side=LEFT,fill=Y)
frame = Frame(root)
frame.pack(side=LEFT,expand=True,fill=BOTH)
editor = Text(frame,font="Consolas 15")
editor.pack(expand=True,fill=BOTH)
tree.bind("<<TreeviewSelect>>",lambda event=None:Open_file_from_list_box(path))
root.mainloop()
uj5u.com熱心網友回復：
iid您只需在內部獲取所選專案Open_file_from_list_box()：
def Open_file_from_list_box(value):
global file
file = tree.selection() # return item iid, not the file name
...
它應該是：
def Open_file_from_list_box(value):
global file
item_id = tree.selection()
file = tree.item(item_id, 'text') # get the filename from 'text' option
...
