Python 移动 pygame 表面不会移动 thorpy 按钮

The first argument of tp.init is supposed to be the screen, but not a surface that is moved on the screen. If you move the surface, you would also have to move the mouse position, respectively the UI would have to evaluate the mouse position relative to the surface. But I don't see any possibility for this.
I suggest drawing the menu on the screen and marking the center of the menu with:

tp.init(screen, tp.theme_round)
...
group.set_center(300, 400)

要使其起作用，需要在绘制场景之后更新UI，但就在更新显示之前.您甚至可以使用曲面的中心来对齐UI.例如:

screen.fill((255, 0, 0))
surface_rect = screen.blit(surface, (100, 0))
game_GUI.element.set_center(*surface_rect.center)
game_GUI.update()
pygame.display.flip()

完整的示例:

import pygame
import thorpy as tp

pygame.init()
def GUI_elements():
    tp.init(screen, tp.theme_round)
    button1 = tp.Button('Main Menu')
    button2 = tp.Button('Exit Game')
    group = tp.Group([button1, button2], 'v')
    game_GUI = group.get_updater()
    return game_GUI

screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("Pygame Window")
surface = pygame.Surface((400, 800))
surface.fill((0, 0, 200))

def main_loop():
    game_GUI = GUI_elements()
    menu_button = game_GUI.element.children[0]
    menu_button.at_unclick = exit
    exit_button = game_GUI.element.children[1]
    exit_button.at_unclick = exit

    running = True
    while running:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False

        screen.fill((255, 0, 0))
        surface_rect = screen.blit(surface, (100, 0))
        game_GUI.element.set_center(*surface_rect.center)
        game_GUI.update()
        pygame.display.flip()

if __name__ == '__main__':
    main_loop()
    pygame.quit()
