PYGLET – 调整大小事件
在本文中,我们将看到如何在Python的 PYGLET 模块中触发 resize 事件。 Pyglet 易于使用但功能强大的库,用于开发视觉丰富的 GUI 应用程序,如游戏、多媒体等。窗口是占用操作系统资源的“重量级”对象。窗口可能显示为浮动区域,也可以设置为填充整个屏幕(全屏)。调整窗口大小时会调用此事件。调度此事件时,窗口将具有 GL 上下文;无需在此处理程序中调用 switch_to。我们可以在 set_size 方法的帮助下改变窗口的大小。
我们可以在下面给出的命令的帮助下创建一个窗口
pyglet.window.Window(width, height, title)
下面是 on resize 事件的语法,这个方法在这个事件被触发时被调用
@window.event
def on_resize(width, height):
print("Window Resized")
下面是实现
Python3
# importing pyglet module
import pyglet
import pyglet.window.key
# width of window
width = 500
# height of window
height = 500
# caption i.e title of the window
title = "Geeksforgeeks"
# creating a window
window = pyglet.window.Window(width, height, title)
# text
text = "GeeksforGeeks"
# creating a label with font = times roman
# font size = 36
# aligning it to the center
label = pyglet.text.Label(text,
font_name ='Times New Roman',
font_size = 36,
x = window.width//2, y = window.height//2,
anchor_x ='center', anchor_y ='center')
new_label = pyglet.text.Label(text,
font_name ='Times New Roman',
font_size = 10,
x = 25, y = 25)
# on draw event
@window.event
def on_draw():
# clearing the window
window.clear()
# drawing the label on the window
label.draw()
# key press event
@window.event
def on_key_press(symbol, modifier):
# key "C" get press
if symbol == pyglet.window.key.C:
print("Key C is pressed")
# on resize event
@window.event
def on_resize(width, height):
# printing some message
print("Window Resized")
print("New Size : ", end = "")
print(width, height)
# image for icon
img = image = pyglet.resource.image("logo.png")
# setting image as icon
window.set_icon(img)
# moving window
window.set_size(300, 400)
# start running the application
pyglet.app.run()
输出 :
Window Resized
New Size : 300 400
