允许调整窗口大小 pyGame

问题描述

我正在尝试允许调整此应用程序的大小，我放置了 RESIZABLE 标志，但是当我尝试调整大小时，它搞砸了！试试我的代码.

I am trying to allow resizing for this app, I put the RESIZABLE flag, but when I try to resize, it messes up! Try my code.

这是一个网格程序，当窗口调整大小时，我希望网格也调整大小/缩小.

It is a grid program, when the window resizes I want the grid to also resize/shrink.

import pygame,math
from pygame.locals import *
# Define some colors
black    = (   0,   0,   0)
white    = ( 255, 255, 255)
green    = (   0, 255,   0)
red      = ( 255,   0,   0)

# This sets the width and height of each grid location
width=50
height=20
size=[500,500]
# This sets the margin between each cell
margin=1


# Initialize pygame
pygame.init()

# Set the height and width of the screen

screen=pygame.display.set_mode(size,RESIZABLE)

# Set title of screen
pygame.display.set_caption("My Game")

#Loop until the user clicks the close button.
done=False

# Used to manage how fast the screen updates
clock=pygame.time.Clock()

# -------- Main Program Loop -----------
while done==False:
    for event in pygame.event.get(): # User did something
        if event.type == pygame.QUIT: # If user clicked close
            done=True # Flag that we are done so we exit this loop
        if event.type == pygame.MOUSEBUTTONDOWN:
            height+=10

    # Set the screen background
    screen.fill(black)

    # Draw the grid
    for row in range(int(math.ceil(size[1]/height))+1):
        for column in range(int(math.ceil(size[0]/width))+1):
            color = white
            pygame.draw.rect(screen,color,[(margin+width)*column+margin,(margin+height)*row+margin,width,height])

    # Limit to 20 frames per second
    clock.tick(20)

    # Go ahead and update the screen with what we've drawn.
    pygame.display.flip()
# Be IDLE friendly. If you forget this line, the program will 'hang'
# on exit.
pygame.quit ()

请告诉我有什么问题，谢谢.

Please tell me whats wrong, thanks.

推荐答案

当窗口更改时，您不会更新宽度、高度或大小.

You are not updating your width, height, or size when the window changes.

来自文档:http://www.pygame.org/docs/ref/display.html

如果显示设置为 pygame.RESIZABLE 标志，pygame.VIDEORESIZE 事件将在用户调整窗口尺寸.

您可以从事件 VIDEORESIZE 中获取新的 size, w, h http://www.pygame.org/docs/ref/event.html

You can get the new size, w, h from the event VIDEORESIZE http://www.pygame.org/docs/ref/event.html
