Button draws image for only a second

Question

So I been trying make it so when I press my button it draws my image forever, but nothing is happening:https://gyazo.com/83017705fa2b3f40ca26112a153791c5 I'm pressing my button but nothing is happening, I want it to draw my image and make my image stay when I press my button

This is what I tried

    if event.type == pygame.MOUSEBUTTONDOWN:
        pos = pygame.mouse.get_pos()
            
    if Abutton.clicked:
        Abutton.clicked = True
        window.blit(A,(0,0))

My full code

import pygame
pygame.init()

# Drawing window screen
window = pygame.display.set_mode((700,500))
# The Name of my window
pygame.display.set_caption("StickMan")
# Drawing the buttons
A = pygame.image.load("A.png")
A2 = pygame.image.load("A1.png")

# Button class
class button1():
    def __init__(self, color, x,y,width,height, text=''):
        self.color = color
        self.x = x
        self.y = y
        self.width = width
        self.height = height
        self.text = text
        self.clicked = False
    def draw(self,window,outline=None):
        #Call this method to draw the button on the screen
        if outline:
            pygame.draw.rect(window, outline, (self.x-2,self.y-2,self.width+4,self.height+4),0)
 
        pygame.draw.rect(window, self.color, (self.x,self.y,self.width,self.height),0)
 
        if self.text != '':
            font = pygame.font.SysFont('comicsans', 60)
            text = font.render(self.text, 1, (0,0,0))
            window.blit(text, (self.x + (self.width/2 - text.get_width()/2), self.y + (self.height/2 - text.get_height()/2)))
 
    def isOver(self, pos):
        #Pos is the mouse position or a tuple of (x,y) coordinates
        if pos[0] > self.x and pos[0] < self.x + self.width:
            if pos[1] > self.y and pos[1] < self.y + self.height:
                return True
 
            return False
 
    def playSoundIfMouseIsOver(self, pos, sound):
        if self.isOver(pos):            
            if not self.over:
                eat.play()
                self.over = True
        else:
            self.over = False

# Color
white = (255,255,255)


def redrawwindow():
    window.fill((0,0,0))

    

    
    Abutton = button1((0,255,0),287,310,55,55, '')

    Abutton.draw(window)

    if event.type == pygame.MOUSEBUTTONDOWN:
        pos = pygame.mouse.get_pos()
            
    if Abutton.clicked:
        Abutton.clicked = True
        window.blit(A,(0,0))



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


        

    redrawwindow()
    pygame.display.update()
pygame.quit()

Answer 1

In this part of your code:

    if event.type == pygame.MOUSEBUTTONDOWN:
        pos = pygame.mouse.get_pos()
            
        if Abutton.isOver(pos):
            window.blit(A,(0,0))

you are telling pygame to only draw A when you click. Simply set a variable, like self.clicked = False, and add self.clicked = True in the if statement. Then, instead of drawing A in the if block, move it out:

if event.type == pygame.MOUSEBUTTONDOWN:
    pos = pygame.mouse.get_pos()
        
if self.clicked:
    window.blit(A,(0,0))

If you only want the image to show while the mouse is over the button, simply change event.type == pygame.MOUSEBUTTONDOWN to event.type == pygame.MOUSEMOTION.

QUESTION EDITED; NEW ANSWER:

The main problem is that you defined your Abutton inside the redrawwindow function. Because you call the function during each iteration of the for loop, the purpose of the self.clicked variable is lost, as in every iteration of the while loop, the Abutton is redefined with self.clicked set to False.

A tip: in your isOver function, you can directly return the expression, as the expression returns a bool value.

The working code:

import pygame
pygame.init()

# Drawing window screen
window = pygame.display.set_mode((700,500))
# The Name of my window
pygame.display.set_caption("StickMan")
# Drawing the buttons
A = pygame.image.load("A.png")
A2 = pygame.image.load("A1.png")

# Button class
class button1():
    def __init__(self, color, x,y,width,height, text=''):
        self.color = color
        self.x = x
        self.y = y
        self.width = width
        self.height = height
        self.text = text
        self.clicked = False
    def draw(self,window,outline=None):
        #Call this method to draw the button on the screen
        if outline:
            pygame.draw.rect(window, outline, (self.x-2,self.y-2,self.width+4,self.height+4),0)
 
        pygame.draw.rect(window, self.color, (self.x,self.y,self.width,self.height),0)
 
        if self.text != '':
            font = pygame.font.SysFont('comicsans', 60)
            text = font.render(self.text, 1, (0,0,0))
            window.blit(text, (self.x + (self.width/2 - text.get_width()/2), self.y + (self.height/2 - text.get_height()/2)))
 
    def isOver(self, pos):
        #Pos is the mouse position or a tuple of (x,y) coordinates
        return pos[0] > self.x and pos[0] < self.x + self.width and pos[1] > self.y and pos[1] < self.y + self.height
 
    def playSoundIfMouseIsOver(self, pos, sound):
        if self.isOver(pos):            
            if not self.over:
                eat.play()
                self.over = True
        else:
            self.over = False

# Color
white = (255,255,255)
Abutton = button1((0,255,0),287,310,55,55, '')

def redrawwindow():
    window.fill((0,0,0))
    Abutton.draw(window)
    if Abutton.clicked:
        window.blit(A,(0,0))


run = True
while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
        elif event.type == pygame.MOUSEBUTTONDOWN:
            pos = pygame.mouse.get_pos()
            if Abutton.isOver(pos):
                Abutton.clicked = True
    redrawwindow()
    pygame.display.update()
pygame.quit()
