在tkinter中,可以使用Treeview小部件来显示层次结构数据,例如树形结构的数据。以下是在tkinter中为应用程序编写Treeview信息的步骤:
import tkinter as tk
from tkinter import ttk
root = tk.Tk()
tree = ttk.Treeview(root)
tree["columns"] = ("Name", "Age", "Gender")
tree.column("#0", width=100)
tree.column("Name", width=100)
tree.column("Age", width=100)
tree.column("Gender", width=100)
tree.heading("#0", text="ID")
tree.heading("Name", text="Name")
tree.heading("Age", text="Age")
tree.heading("Gender", text="Gender")
# 添加根节点
root_node = tree.insert("", "end", text="Root", values=("John Doe", "30", "Male"))
# 添加子节点
child_node = tree.insert(root_node, "end", text="Child", values=("Jane Smith", "25", "Female"))
tree.pack()
完整的示例代码如下:
import tkinter as tk
from tkinter import ttk
root = tk.Tk()
tree = ttk.Treeview(root)
tree["columns"] = ("Name", "Age", "Gender")
tree.column("#0", width=100)
tree.column("Name", width=100)
tree.column("Age", width=100)
tree.column("Gender", width=100)
tree.heading("#0", text="ID")
tree.heading("Name", text="Name")
tree.heading("Age", text="Age")
tree.heading("Gender", text="Gender")
root_node = tree.insert("", "end", text="Root", values=("John Doe", "30", "Male"))
child_node = tree.insert(root_node, "end", text="Child", values=("Jane Smith", "25", "Female"))
tree.pack()
root.mainloop()
这样,您就可以在tkinter应用程序中使用Treeview小部件来显示层次结构数据了。
