在我的treeview (python tkinter)中，当我添加数据时，我希望根据父名称(tkinter)添加数据.

Question

在我的TreeView中，我手动输入值，我想让它们像这样显示:

Parent name1
child 1 
child 2 

child 3 
parent name 2 
child 1 
child 2 

我输入的数据应该在每次输入时作为子数据添加到各自的父数据中(输入的父名称应该与treeview中已有的父名称进行检查)。注:只有当故障率为数值时，数据才会输入到TreeView中。

#treeview
my_tree = ttk.Treeview(tree_frame,height= 15, yscrollcommand=tree_scroll.set)
my_tree.pack()
tree_scroll.config(command=my_tree.yview)
my_tree['columns'] = ("fun"," rate", "cv", "id")
my_tree.column("#0",width=100)
my_tree.column("fun",anchor=W,width=100)
my_tree.column("rate",anchor=W,width=100)
my_tree.column("cv",anchor=W,width=120)
my_tree.column("id",anchor=W,width=120)
my_tree.heading("#0",text='name',anchor=W)
my_tree.heading("fun", text='Fun', anchor=W)
my_tree.heading("rate",text='rate',anchor=W)
my_tree.heading("cv", text='Cv',anchor=W)
my_tree.heading("id",text='id',anchor=W)
main.mainloop()

首先所有的ieX都是None，因为它是.grid(...)的结果。你需要像这样分割行:

ie1 = Entry(input_frame, width = 50).grid(row=0, column=1,padx=5,pady=5)

分成两行:

ie1 = Entry(input_frame, width = 50)
ie1.grid(row=0, column=1,padx=5,pady=5)

则需要修改add()，分别插入父和子:

def add():
global count
a = ie3.get()
try:
float(a)
component = ie1.get()
if not my_tree.exists(component):
# insert parent
my_tree.insert(parent="", index="end", iid=component, text=component)
# insert child
my_tree.insert(parent=component, index='end', iid=count, values=(ie2.get(),ie3.get(),ie4.get(),ie5.get()))                                                                                         
count += 1
except ValueError:
