如何填充tkinter中由循环创建的输入框

Question

基本上我创建了许多输入框，我想在单击特定按钮时填充它，但当我这样做时，它只填充最后一个。我知道我可以一个一个地创建方框，但是有没有办法这样做呢?

def Roll_Dice(Dice):
if Dice=="d6":
Rolls=[]
for i in range(0,4):
Rolls.append(random.randint(1,6))
return Rolls
elif Dice=="d20":
return random.randint(1,20)
def check(name):
if name=="Str":
StrDice.append(Roll_Dice("d6"))
StrRoll.config(state="disabled")
Fill(name,StrDice)
def Fill(stat,list):
if stat=="Str":
for i in range(0,4):
strength.insert(i,list[i])
STR=LabelFrame(root,text="Str")
STR.place(x=10,y=10)
j=0
for i in range(0,4):
j+=1
strength=Entry(STR)
strength.grid(row=j,column=0,pady=5)

STATS=Frame(root)
STATS.place(x=10,y=150)
StrRoll=Button(STATS,text="Roll for your Str stats",command=lambda:check("Str"))
StrRoll.grid(row=0,column=0,columnspan=1,padx=2)

下面是我的代码:

from tkinter import*
import functions
import random
root=Tk()
StrDice=[]
DexDice=[]
IntDice=[]
ConsDice=[]
WisDice=[]
CharDice=[]
def Roll_Dice(Dice):
if Dice=="d6":
Rolls=[]
for i in range(0,4):
Rolls.append(random.randint(1,6))
return Rolls
elif Dice=="d20":
return random.randint(1,20)
def check(name):
if name=="Str":
StrDice.append(Roll_Dice("d6"))
StrRoll.config(state="disabled")
Fill(name,StrDice)
elif name=="Dex":
DexDice.append(Roll_Dice("d6"))
DexRoll.config(state="disabled")
elif name=="Int":
IntDice.append(Roll_Dice("d6"))
IntRoll.config(state="disabled")
elif name=="Cons":
ConsDice.append(Roll_Dice("d6"))
ConsRoll.config(state="disabled")
elif name=="Wis":
WisDice.append(Roll_Dice("d6"))
WisRoll.config(state="disabled")
else:
CharDice.append(Roll_Dice("d6"))
CharRoll.config(state="disabled")
def Fill(stat,list):
if stat=="Str":
for i in range(0,4):
strength.insert(i,list[i])
pass
Stats=["Str","Dex","Int","Cons","Wis","Char"]
STR=LabelFrame(root,text="Str")
STR.place(x=10,y=10)
j=0
for i in range(0,4):
j+=1
strength=Entry(STR)
strength.grid(row=j,column=0,pady=5)
DEX=LabelFrame(root,text="Dex")
DEX.place(x=140,y=10)
j=0
for i in range(0,4):
j+=1

IntRoll=Button(STATS,text="Roll for your Int stats",command=lambda:check("Int"))
IntRoll.grid(row=0,column=2,columnspan=1,padx=2)
ConsRoll=Button(STATS,text="Roll for your Cons stats",command=lambda:check("Cons"))
ConsRoll.grid(row=0,column=3,columnspan=1,padx=2)
WisRoll=Button(STATS,text="Roll for your Wis stats",command=lambda:check("Wis"))
WisRoll.grid(row=0,column=4,columnspan=1,padx=2)
CharRoll=Button(STATS,text="Roll for your Char stats",command=lambda:check("Char"))
CharRoll.grid(row=0,column=5,columnspan=1,padx=2)
root.mainloop()

你可以做很多事情来简化你想要达到的目标，但我将保持简单，只回答你的问题。

在您创建小部件的循环中，您在每次迭代中重新分配变量。当循环结束时，第一个示例中的变量'strength'只引用了最后创建的条目小部件。

一个简单的解决方案是将小部件放在一个列表中:

strength = []
for i in range(4):
strength.append(Entry(STR))
strength[i].grid(row=i, column=0, pady=5

之后插入:

strength[i].insert(0, value)

编辑:下面是一个简化/缩短代码的简单示例。总数假设你做了4d6，把最低的去掉。

import random
import tkinter as tk
from tkinter import ttk

STAT_BLOCKS = ['STR', 'DEX', 'CON', 'WIS', 'INT', 'CHA']
fields = {}
buttons = {}
labels = {}
def roll_dice(num_sides, num_dice=1):
return [random.randint(1, num_sides) for i in range(num_dice)]
def fill(stat, rolled_values):
for idx, value in enumerate(rolled_values):
fields[stat][idx].insert(0, value)
buttons[stat].config(state='disabled')
labels[stat].config(text=f'Total: {sum(sorted(rolled_values)[1:])}')
def reset():
for stat in STAT_BLOCKS:
for field in fields[stat]:
field.delete(0, 'end')
buttons[stat].config(state='normal')
labels[stat].config(text='')

root = tk.Tk()
for stat in STAT_BLOCKS:
frame = ttk.Labelframe(root, text=stat)
frame.pack(side='left', padx=10)
buttons[stat] = ttk.Button(
frame,
text='ROLL',
command=lambda s=stat: fill(s, roll_dice(6, 4))
)
buttons[stat].pack(pady=5)
fields[stat] = [ttk.Entry(frame, width=3, justify='right')
for i in range(4)]
for field in fields[stat]:
field.pack(pady=(0, 5))
labels[stat] = ttk.Label(frame)
labels[stat].pack(pady=(0, 5))
reset_button = ttk.Button(text='Reset', command=reset).pack(side='right', padx=(0, 10))
root.mainloop()
