Tkinter Grid Overlapping

I am building a calendar that allows the user to cycle through the months and years by pressing the buttons created of the previous month and next month. Essentially what I want th

Solution 1:

This is a modified version of the proposed answer that also includes the original desired intent of allowing the user to cycle through the months and will also increment the year.

Solution 2:

Tkinter is fairly efficient. And for the number of widgets that you have, it won't impact performance much to create them all initially. Here is a sample that works about like what you were trying to do.

from calendar import *
import datetime
try:
    from tkinter import *   # Python 3.xexcept:
    from Tkinter import *   # Python 2.xclassApplication(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 - 1for i inrange(3):
            if amonth < 0:
                amonth = 11
                year -= 1elif amonth == 12:
                amonth = 0
                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)


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

    defshowMonth(self, mFrame, mButton):
        # Display all buttons normallyfor button in self.buttonList:
            button['relief'] = 'raised'# Set this month's button relief to flat

            frame.grid_remove()

        mFrame.grid()

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

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