Image buttons cannot be integrated

[MaxNacemit]

I tried to integrate an image button into my pygame code, following the exact steps of the tutorial. It gave me the error of "NoneType object has no attribute 'size'". I traced it to the get_current_application function, which apparently returns nothing. When I replaced the image button with a button, everything started working.

What is the Python and Pygame version used ?

[MaxNacemit]

Python 3.6/Pygame 1.9

I cannot reproduce the bug. Are you reallly copy/pasting the code from the tutorial ? If so, can you post the entire error traceback with lines numbers ?

Same issue. I use Python 3.7.4/pygame 1.9.6/ThorPy 1.6.2

The bug happens when you include thorpy image object into another pygame code. It doesn't concern thorpy applications.

This is the tutorial on including thorpy in a pre-existing code. I replaced the make_button by make_image_button.

#Tutorial : how to use ThorPy with a pre-existing code - step 1

QUIT_BUTTON_IMAGE = "ressources/constantes/quitbuttonimage.png"

import pygame, thorpy

pygame.init()
pygame.key.set_repeat(300, 30)
screen = pygame.display.set_mode((400,400))
screen.fill((255,255,255))
rect = pygame.Rect((0, 0, 50, 50))
rect.center = screen.get_rect().center
clock = pygame.time.Clock()

pygame.draw.rect(screen, (255,0,0), rect)
pygame.display.flip()

#declaration of some ThorPy elements ...
slider = thorpy.SliderX(100, (12, 35), "My Slider")
button = thorpy.make_image_button(QUIT_BUTTON_IMAGE)
box = thorpy.Box(elements=[slider,button])
#we regroup all elements on a menu, even if we do not launch the menu
menu = thorpy.Menu(box)
#important : set the screen as surface for all elements
for element in menu.get_population():
    element.surface = screen
#use the elements normally...
box.set_topleft((100,100))
box.blit()
box.update()

playing_game = True
while playing_game:
    clock.tick(45)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            playing_game = False
            break
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                pygame.draw.rect(screen, (255,255,255), rect) #delete old
                pygame.display.update(rect)
                rect.move_ip((-5,0))
                pygame.draw.rect(screen, (255,0,0), rect) #drat new
                pygame.display.update(rect)
        menu.react(event) #the menu automatically integrate your elements

pygame.quit()

Same error happens when you use Image(path="path/to/an/image").

Also thank you for this lib, really helped me with my projects.

I updated the code so that it can be used outside of a thorpy application. Thanks for your useful comments !
