Python GUI – make a button – python programming

This library uses pygame and lets you use some widgets ready to be used in your games.

Installation

If you do not have pygame

pip install pygame

If you want to use pygame 2 with python 3.8 use this

pip install pygame==2.0.0.dev10

Check for more recent version of this. Maybe there is an official version of pygame 2 for python 3.8 or more when you read this.

To install pygame_gui:

pip install pygame_gui

Your first program

Taken from the official documentation, here is how you make a button in a window. The repository og pygame_gui is here.

import pygame
import pygame_gui
import sys


pygame.init()

pygame.display.set_caption('Quick Start')
window_surface = pygame.display.set_mode((800, 600))

background = pygame.Surface((800, 600))
background.fill(pygame.Color('#000000'))

manager = pygame_gui.UIManager((800, 600))

hello_button = pygame_gui.elements.UIButton(relative_rect=pygame.Rect((350, 275), (100, 50)),
                                            text='Say Hello',
                                            manager=manager)

clock = pygame.time.Clock()
is_running = True

while is_running:
    time_delta = clock.tick(60)/1000.0
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            is_running = False

        if event.type == pygame.USEREVENT:
            if event.user_type == pygame_gui.UI_BUTTON_PRESSED:
                if event.ui_element == hello_button:
                    print('Hello World!')

        manager.process_events(event)

    manager.update(time_delta)

    window_surface.blit(background, (0, 0))
    manager.draw_ui(window_surface)

    pygame.display.update()

pygame.quit()
sys.exit()
