I have some issues with the fullscreen option of pygame. Here is some code that simply draws a blue window and by pressing R we can switch between blue and purple. Then we can also toggle between fullscreen and windowed mode using F or G. F is implemented explicitly and G uses the method toggle_fullscreen()
.
import pygame, sys
from pygame.locals import *
#Initializes pygame
pygame.init()
#Defines the Clock object
clock = pygame.time.Clock()
#Just draws a blue screen
size = (960, 540)
blue = (0,0,100)
purp = (100,0,100)
is_blue = True
display_surf = pygame.display.set_mode(size, RESIZABLE)
display_surf.fill(blue)
mainLoop = True
is_fullscreen = False
#Mainloop
while mainLoop:
dt = clock.tick(12)
for event in pygame.event.get():
if event.type == pygame.QUIT:
mainLoop = False
if event.type == pygame.KEYDOWN:
#Single key pressed
if event.key == K_f:
#Toggles fullscreen
is_fullscreen = not is_fullscreen
old_surface = display_surf
setmode = FULLSCREEN if is_fullscreen else RESIZABLE
display_surf = pygame.display.set_mode(size, setmode)
display_surf.blit(old_surface, (0,0))
del old_surface
if event.key == K_q:
#Quits the app
mainLoop = False
if event.key == K_r:
#Redraws the blue or purple
print("Trying to flip colors")
display_surf.fill(purp if is_blue else blue)
is_blue = not is_blue
if event.key == K_g:
#Toggles fullscreen with the dedicated method
is_fullscreen = not is_fullscreen
pygame.display.toggle_fullscreen()
pygame.display.update()
pygame.quit()
I am on Ubuntu 18.04 using Python 3.6.8. Here are my observations:
- Using pygame 2.0.0.dev6, when going fullscreen with either F or G the screen does the following:
- flashes a few times
- goes in the task bar as a minimized icon
- if I click on the icon the screen flashes a few more times and finally we are fullscreen
- problem: the screen is entirely black and the button R does not flip the colors (but prints the message)
- Still using pygame 2.0.0.dev6. In this case the G and the F button behave differently: when going back from fullscreen to windowed with G, the R button doesn't flip the colors, even in the windowed version. When using F instead it works.
- With pygame version 2.0.0.dev3 the G button does not work at all, while F has the same behavior as before.
My major problem is 1.4.: the fullscreen mode is entirely black.
Now let's do a modification. Change the following line in the code for the F button
setmode = FULLSCREEN|SCALED if is_fullscreen else RESIZABLE #FULLSCREEN -> FULLSCREEN|SCALED
This goes fullscreen with the current screen resolution and not the one I specify at the top. Now the problems 1.1., 1.2 and 1.3. are gone: the app goes to fullscreen immediately. But the problem 1.4. persists and furthermore the program does not accept inputs anymore. If I press Q it won't quit. It doesn't take Alt+Tab or Alt+F4 and so I have to restart the computer.
