在treeview tkinter python中搜索并选择项

我想创建

search\u函数

来搜索treeview表中的数据。 在我的代码中，我确实需要单击

search_按钮

，根据下面的3个请求选择treeview表中的数据

from tkinter import *
from tkinter import ttk

GUI = Tk()
GUI.geometry('1920x1080')

tree_view_frame = Frame(GUI)
tree_view_frame.pack()
tree_scroll = Scrollbar(tree_view_frame)
tree_scroll.pack(side = RIGHT, fill = Y)
header = ['Part No.', 'Name', 'Unit', 'Quan', 'Price','Total', 'Initial Total']
hdsize = [60,240,60,60,70,80,80]
aanchor = [W,W,E,E,E,E,E]
global product_table
product_table = ttk.Treeview(tree_view_frame, columns = header, show = 'headings', height = 20, yscrollcommand=tree_scroll.set, selectmode="extended")
def treeview_sort_column(product_table, col, reverse):
    l = [(product_table.set(k, col), k) for k in product_table.get_children('')]
    l.sort(reverse=reverse)
    for index, (val, k) in enumerate(l):
        product_table.move(k, '', index)
    product_table.heading(col, command=lambda _col=col: treeview_sort_column(product_table, _col, not reverse))
for col in header:
    product_table.heading(col, text=col,command=lambda _col=col: treeview_sort_column(product_table, _col, False))
product_table.pack()
tree_scroll.config(command = product_table.yview)
for h,s,a in zip(header, hdsize, aanchor):
    product_table.heading(h, text = h)
    product_table.column(h,width = s, anchor = a)

Nameget = StringVar()
E_namme = ttk.Entry(GUI,textvariable = Nameget)
E_namme.pack()

def Add_Product(event = None):
    product_table.insert('', 'end', value = ('', Nameget.get()))
B_Add_product = ttk.Button(GUI, text = "Add Product", command = Add_Product)
B_Add_product.pack()

def search_function():
    query = Nameget.get()
    selections = []
    for child in product_table.get_children():
        if query in product_table.item(child)['values'][1]:
            selections.append(child)
            product_table.selection_set(selections[0])
            product_table.focus(selections[0])
    product_table.focus_force()
search_button = ttk.Button(GUI, text = "search_button", width = 15, command = search_function)
search_button.pack()

GUI.mainloop()

第一次单击是选择第一个结果。

第二次或下一次单击是选择下一个结果，直到最后一个结果，并作为循环执行。

自动向下滚动滚动条以选择当前页面中未显示的结果。

在当前代码中，它只能选择第一个结果，不能自动向下滚动滚动条

---

提前谢谢。

您可以使用

查看（确保项目可见）并循环

在这里，任何数据结构都有助于使用
队列
或
dict
，如下例所示：

（使用一些OOP很好）

谢谢，我的第三个请求正在运行，但第二个请求没有被修复。@VittawatLaorungroj Edited代码正在将所选结果从第一行移到另一行。但我需要的只是将选择行从一个结果移动到另一个结果。@VittawatLaorungroj editedit的工作非常感谢
