Question

我对自己面临的问题感到非常困惑。我花了一些时间来尽力解决这个问题，这里是：

我正在使用tkinter和ttk，我想创建一个按钮网格，就像下面的代码一样：（取自https://www.edureka.co/community/1539/tkinter-grid-overlapping-issue） TL; DR：只是一个工作日历，每天在网格中都有一个按钮

from calendar import *
import datetime
try:
    from tkinter import *   # Python 3.x
except:
    from Tkinter import *   # Python 2.x


class Application(Frame):

    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.grid(row=0, column=0, sticky='news')

        DateNow = datetime.datetime.now()
        month = int(DateNow.month)
        year = int(DateNow.year)
        self.createDaysOfWeekLabels()
        month_name = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        # Create frames and button controls for previous, current and next month.
        self.frameList = []    # List that contains the frame objects.
        self.buttonList = []   # List that contains the button objects.
        amonth = month - 1
        for i in range(3):
            if amonth < 0:
                amonth = 11
                year -= 1
            elif amonth == 12:
                amonth = 1
                year += 1

            mFrame = Frame(self)
            self.createMonth(mFrame, amonth, year)
            self.frameList.append(mFrame)
            mButton = Button(self, text=month_name[amonth-1])
            mButton['command'] = lambda f=mFrame, b=mButton: self.showMonth(f, b)
            mButton.grid(row=0, column=i)
            # Grid each frame
            mFrame.grid(row=2, column=0, columnspan=7, sticky='news')
            if (i == 1):
                mButton['relief'] = 'flat'
            else:
                # Remove all but the ith frame. More efficient to remove than forget and configuration is remembered.
                mFrame.grid_remove()
            self.buttonList.append(mButton)
            amonth += 1

        # Create year widget at top left of top frame
        label = Label(self, text=year)#displaying year
        label.grid(row=0, column=6)


    def createDaysOfWeekLabels(self):
        days = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
        for i in range(7):
            label = Label(self, text=days[i])
            label.grid(row = 1, column = i)

    def showMonth(self, mFrame, mButton):
        # Display all buttons normally
        for button in self.buttonList:
            button['relief'] = 'raised'

        # Set this month's button relief to flat
        mButton['relief'] = 'flat'

        # Hide all frames
        for frame in self.frameList:
            frame.grid_remove()

        mFrame.grid()

    def createMonth(self, mFrame, month, year):
        weekday, numDays = monthrange(year, month)
        week = 0
        for i in range(1, numDays + 1):
            button = Button(mFrame, text = str(i), width=3)
            button.grid(row = week, column = weekday)

            weekday += 1

            if weekday > 6:
                week += 1
                weekday = 0

mainWindow = Tk()
obj = Application(mainWindow)
mainWindow.mainloop()

然后我尝试做类似的事情，但是使用字典，其键是坐标元组，值是按钮（以父帧为框架），像这样：

coords = {(0, 0):ttk.Button(self.frame_p1g), (0, 1): ttk.Button(self.frame_p1g)}

我刚刚对我的网格使用了同样的字典，下面的代码很完美：

x = 2
    for i in coords.values():
        i.grid(row=x, column=2)
        x += 1

Image of the result

但是，只要我使用一个简单的函数自动生成一个网格，然后将其放置在网格中，它就不会起作用：

def make(width, height, element):
grid = {}
for y in range(height):
    for x in range(width):
        print ("X: " + str(x))
        print ("Y: " + str(y))
        grid[x, y] = element
return grid

Image with result

我试图找到原因，但是我唯一能找到的是该函数似乎创建了完全相同的按钮，并且当我尝试放置它们时，每个按钮都具有相同的行和列配置：

Dict print from working dict

Dict print from bugged list

这是放置每个按钮的代码（与另一个按钮非常相似，只是使用字典的长度来知道将其放置在何处）

    self.p1g = make(int(self.size[0]), int(self.size[1]), ttk.Button(self.frame_p1g))
    print(self.p1g)
    x = 2
    y = 2
    for butt in self.p1g.values():
        butt.grid(row=y, column=x)
        x += 1
        if x > (list(self.p1g.keys())[-1][0]):
            x = 2
            y += 1

问题：如何使它与字典配合使用（我真的需要那些坐标来引用按钮）

python字典中的ttk按钮引用了同一对象，生成问题？
