如何使用按钮将值输入到不同的输入框中？

Question

我对 python 非常陌生，我正在尝试制作一个可以跟踪篮球比赛中团队成员统计数据的程序。我对设计没有任何问题，但功能是一个难题，我不确定如何拥有它，以便我可以按下按钮并将正确的积分和统计数据分配给正确的团队成员。

我希望能够选择输入框，然后按其中一个按钮来添加积分/统计数据，或者使用菜单功能并让它以这种方式工作。

Answer 1

创建一个球员姓名字典，其值为球员的行号。然后，您可以使用.grid_slaves(row, column) 在该位置获取小部件。

这应该是你增加积分的功能

def addPoints(column):

    widget = newWindow.grid_slaves(row=playerDic[selectPlayer.get()], column=column)[0]

    currentScore = widget.get()

    if currentScore == '':
        currentScore = 0

    widget['state'] = 'normal'
    widget.delete(0, 'end')
    widget.insert(0, int(currentScore) + 1)
    widget['state'] = 'readonly'

你的选项菜单：

selectPlayer = StringVar()
selectPlayer.set("john")

playerDic = {"john": 2, "simon": 3, "joel": 5, "kaur": 6, "genom": 7, "kieran": 8} # row values

menu = OptionMenu(newWindow, selectPlayer, *playerDic.keys()).grid(row=10, column=1)

并且您的按钮必须传递列号。像这样的：

twoButton = Button(newWindow,text = '2pt +', command=lambda :addPoints(2)).grid(row=10, column=3)
threeButton = Button(newWindow,text = '3pt +', command=lambda :addPoints(3)).grid(row=10, column=4)
assistButton = Button(newWindow,text = 'Assist +', command=lambda :addPoints(4)).grid(row=10, column=5)
reboundButton = Button(newWindow,text = 'Rebound +', command=lambda :addPoints(5)).grid(row=10, column=6)
stealButton = Button(newWindow,text = 'Steal +', command=lambda :addPoints(6)).grid(row=10, column=7)
blockButton = Button(newWindow,text = 'Block +', command=lambda :addPoints(7)).grid(row=10, column=8)
turnoverButton = Button(newWindow,text = 'Turnover +', command=lambda :addPoints(8)).grid(row=10, column=9) 

注意：如果您更改条目小部件的行或列，请不要忘记更新 command=lambda :addPoints(column) 中的字典和列号

_{附带说明：您还应该知道分配给<widget>.grid() 的所有变量都是None，因为.grid() 返回None，所以您的所有变量都几乎没有用。}

使用

Button(newWindow, text='2pt +', command=lambda: click(1))

创建按钮回调函数并将按钮的值传递给函数

您的按钮应如下所示

def click(a):
    print(a)

twoButton = Button(newWindow, text='2pt +', command=lambda: click(1)).grid(row=10, column=3)
threeButton = Button(newWindow, text='3pt +', command=lambda: click(2)).grid(row=10, column=4)
assistButton = Button(newWindow, text='Assist +', command=lambda: click(3)).grid(row=10, column=5)
reboundButton = Button(newWindow, text='Rebound +', command=lambda: click(4)).grid(row=10, column=6)
stealButton = Button(newWindow, text='Steal +', command=lambda: click(5)).grid(row=10, column=7)
blockButton = Button(newWindow, text='Block +', command=lambda: click(6)).grid(row=10, column=8)
turnoverButton = Button(newWindow, text='Turnover +', command=lambda: click(7)).grid(row=10, column=9)
