I'd like to use some features from pygame (sprite graphics) in my GUI I made in Tkinter. I know of OcempGUI, but I'd prefer to stick to Tkinter, just use some modules from pygame. This is similar but not quite the same. Is this possible at all? What are potential problems (event loop)?
This works on Linux. If you're lucky, it might work on other operating systems as well.
import Tkinter as tk
import os
w, h = 500, 200
# Add a couple widgets. We're going to put pygame in `embed`.
root = tk.Tk()
embed = tk.Frame(root, width=w, height=h)
embed.pack()
text = tk.Button(root, text='Blah.')
text.pack()
# Tell pygame's SDL window which window ID to use
os.environ['SDL_WINDOWID'] = str(embed.winfo_id())
# The wxPython wiki says you might need the following line on Windows
# (http://wiki.wxpython.org/IntegratingPyGame).
#os.environ['SDL_VIDEODRIVER'] = 'windib'
# Show the window so it's assigned an ID.
root.update()
# Usual pygame initialization
import pygame as pg
pg.display.init()
screen = pg.display.set_mode((w,h))
pos = 0
while 1:
# Do some pygame stuff
screen.fill(pg.Color(0,0,0))
pos = (pos + 1) % screen.get_width()
pg.draw.circle(screen, pg.Color(255,255,255), (pos,100), 30)
# Update the pygame display
pg.display.flip()
# Update the Tk display
root.update()

A friend and I are making a game in pygame. We would like to have a pygame window embedded into a tkinter or WxPython frame, so that we can include text input, buttons, and dropdown menus that are supported by WX or Tkinter. I have scoured the internet for an answer, but all I have found are people asking the same question, none of these have been well answered.
What would be the best way implement a pygame display embedded into a tkinter or WX frame? (TKinter is preferable)
Any other way in which these features can be included alongside a pygame display would also work.
(Note this solution does not work on Windows systems with Pygame 2.
See Using 'SDL_WINDOWID' does not embed pygame display correctly into another application #1574. You can currently download older versions of Pygame here.)
According to this SO question and the accepted answer, the simplest way to do this would be to use an SDL drawing frame.
This code is the work of SO user Alex Sallons.
import os
import pygame
import Tkinter as tk
from Tkinter import *
root = tk.Tk()
embed = tk.Frame(root, width = 500, height = 500) #creates embed frame for pygame window
embed.grid(columnspan = (600), rowspan = 500) # Adds grid
embed.pack(side = LEFT) #packs window to the left
buttonwin = tk.Frame(root, width = 75, height = 500)
buttonwin.pack(side = LEFT)
os.environ['SDL_WINDOWID'] = str(embed.winfo_id())
os.environ['SDL_VIDEODRIVER'] = 'windib'
screen = pygame.display.set_mode((500,500))
screen.fill(pygame.Color(255,255,255))
pygame.display.init()
pygame.display.update()
def draw():
pygame.draw.circle(screen, (0,0,0), (250,250), 125)
pygame.display.update()
button1 = Button(buttonwin,text = 'Draw', command=draw)
button1.pack(side=LEFT)
root.update()
while True:
pygame.display.update()
root.update()
This code is cross-platform, as long as the windib SDL_VIDEODRIVER line is omitted on non Windows systems. I would suggest
# [...]
import platform
if platform.system == "Windows":
os.environ['SDL_VIDEODRIVER'] = 'windib'

I'm trying to embed an SDL2 window into my Tkinter application, via pySDL2. How do I setup my pySDL2 window, renderer so that my rendering or drawing appears inside an embedded frame?
Other examples have shown for pygame, but I've discovered that my version of pygame currently does not properly work with SDL2. I understand that there are other implementations of pygame that are attempting to implement SDL2, but compatibility with SDL2 is of primary importance to me.
An example of this working correctly would be a frame in a Tkinter window having a screen which when a button is clicked, draws something to the frame via the pySDL2 API.
In attempting to use the pygame solution found elsewhere, I received a few different errors including BadWindow, BadDrawable (related to X server functions.)
Examples for this were difficult to find, so hopefully this answer will help others. In working with the pySDL2 wrapper API, you need to know about ctypes for different operations. In some cases, the API has been extended to avoid some of these seemingly arcane actions. An example code is provided and then explained below.
from sdl2 import *
import tkinter as tk
from tkinter import *
import random, ctypes
def draw():
global renderer
x1 = ctypes.c_int(random.randrange(0, 600))
y1 = ctypes.c_int(random.randrange(0, 500))
x2 = ctypes.c_int(random.randrange(0, 600))
y2 = ctypes.c_int(random.randrange(0, 500))
r = ctypes.c_ubyte(random.randrange(0, 255))
g = ctypes.c_ubyte(random.randrange(0, 255))
b = ctypes.c_ubyte(random.randrange(0, 255))
SDL_SetRenderDrawColor(renderer, r, g, b, ctypes.c_ubyte(255))
SDL_RenderDrawLine(renderer, x1, y1, x2, y2)
def sdl_update():
global window, event, renderer
SDL_RenderPresent(renderer);
if SDL_PollEvent(ctypes.byref(event)) != 0:
if event.type == SDL_QUIT:
SDL_DestroyRenderer(renderer)
SDL_DestroyWindow(window)
SDL_Quit()
# tkinter stuff #
root = tk.Tk()
embed = tk.Frame(root, width = 500, height = 500) #creates embed frame for pygame window
embed.grid(columnspan = (600), rowspan = 500) # Adds grid
embed.pack(side = LEFT) #packs window to the left
buttonwin = tk.Frame(root, width = 75, height = 500)
buttonwin.pack(side = LEFT)
button1 = Button(buttonwin,text = 'Draw', command=draw)
button1.pack(side=LEFT)
root.update()
#################################
# SDL window stuff #
SDL_Init(SDL_INIT_VIDEO)
window = SDL_CreateWindowFrom(embed.winfo_id())
renderer = SDL_CreateRenderer(window, -1, 0)
SDL_SetRenderDrawColor(renderer, ctypes.c_ubyte(255), ctypes.c_ubyte(255),
ctypes.c_ubyte(255), ctypes.c_ubyte(255))
SDL_RenderClear(renderer)
event = SDL_Event()
draw()
while True:
sdl_update()
root.update()
The example above shows that you can create your tkinter GUI, and then initialize your pySDL2 code, creating a window from whichever frame or window you want, in this case, I've chosen to use a frame I've created, called embed. Using the winfo_id() function available (see the tkinter docs) we can get a handle to the window. The draw() function simply does the drawing using the render module. Notice that for the SDL2 functions that expect certain types, ctypes is used to format those parameters in a way that is expected by SDL2. In the main while loop, a call to the sdl_update() function checks for SDL events. That is followed by the root window (tkinter) update call.
The Button we created has its command linked to draw() and when you click this button, a randomly colored line appears in the frame the SDL2 window is linked to.
This code was adapted from This SO answer from PythonNut regarding pygame and tkinter. That code was originally by user Alex Sallons.
I am trying to make a fullscreen window with tkinter but the window covers the whole screen including the windows taskbar.How do i make the window fit nicely into the screen without covering the taskbar? Here is my source code:
from tkinter import*
my_window = Tk()
my_window.title("Demo")
screen_width = my_window.winfo_screenwidth()
screen_height = my_window.winfo_screenheight()
x = (screen_width /2) - (width_of_window/2)
y = (screen_height/2) -(height_of_window/2)
my_window.geometry("%dx%d+0+0"%
(my_window.winfo_screenwidth(),my_window.winfo_screenheight())
my_window.mainloop()
I am coding in windows 10 using vs code.
This seems to be a difficult task. The easiest way I have found is to:
my_window.wm_state('zoomed')
This corresponds to maximized, but not fullscreen. This does not seem to work on all platforms.
