How to set a tkinter window to a constant size

Question

I m programming a little game with tkinter and briefly  I m stuck   I have a kind od starting menu  in which are two buttons and one label   If I just create the frame everything is fine  it has the size 500x500 pixels  I want the background not to change when I create the buttons and the labe  but it adapts the size whatever I do  Here is my code   import tkinter as tk  def startgame        pass  mw   tk Tk                 Here I tried  1  mw title  The game    back   tk Frame master mw  width 500  height 500  bg  black   back pack    go   tk Button master back  text  Start Game   bg  black   fg  red                        command lambda startgame    pack   close   tk Button master back  text  Quit   bg  black   fg  red                        command lambda quit    pack   info   tk Label master back  text  Made by me    bg  red                            fg  black   pack    mw mainloop     I ve searched around on stackoverflow and didn t get anything useful  I ve found just one question a bit similar to mine but the answer didn t work  I tried this    1   mw resizable width False  height False   I can t imagine what is the problem  I m really desperate

Here is the most simple way  import tkinter as tk  root   tk Tk    root geometry  200x200   root resizable width 0  height 0   root mainloop    I don t think there is anything to specify  It s pretty straight forward

If you want a window as a whole to have a specific size  you can just give it the size you want with the geometry command  That s really all you need to do   For example   mw geometry  500x500     Though  you ll also want to make sure that the widgets inside the window resize properly  so change how you add the frame to this   back pack fill  both   expand True

You turn off pack propagate by setting pack propagate 0   Turning off pack propagate here basically says don t let the widgets inside the frame control it s size  So you ve set it s width and height to be 500  Turning off propagate stills allows it to be this size without the widgets changing the size of the frame to fill their respective width   heights which is what would happen normally  To turn off resizing the root window  you can set root resizable 0  0   where resizing is allowed in the x and y directions respectively   To set a maxsize to window  as noted in the other answer you can set the maxsize attribute or minsize although you could just set the geometry of the root window and then turn off resizing  A bit more flexible imo   Whenever you set grid or pack on a widget it will return None  So  if you want to be able to keep a reference to the widget object you shouldn t be setting a variabe to a widget where you re calling grid or pack on it  You should instead set the variable to be the widget Widget master        and then call pack or grid on the widget instead   import tkinter as tk  def startgame         pass  mw   tk Tk     If you have a large number of widgets  like it looks like you will for your  game you can specify the attributes for all widgets simply like this  mw option add   Button Background    black   mw option add   Button Foreground    red    mw title  The game    You can set the geometry attribute to change the root windows size mw geometry  500x500    You want the size of the app to be 500x500 mw resizable 0  0   Don t allow resizing in the x or y direction  back   tk Frame master mw bg  black   back pack propagate 0   Don t allow the widgets inside to determine the frame s width   height back pack fill tk BOTH  expand 1   Expand the frame to fill the root window   Changed variables so you don t have these set to None from  pack   go   tk Button master back  text  Start Game   command startgame  go pack   close   tk Button master back  text  Quit   command mw destroy  close pack   info   tk Label master back  text  Made by me    bg  red   fg  black   info pack    mw mainloop

There are 2 solutions for your problem    Either you set a fixed size of the Tkinter window                  mw geometry  500x500     OR   Make the Frame adjust to the size of the window automatically back place x   0  y   0  relwidth   1  relheight   1     The second option should be used in place of back pack

Try parent window maxsize x x   to set the maximum size  It shouldn t get larger even if you set the background  etc   Edit  use parent window minsize x x  also to set it to a constant size
