PYGLET – 隐藏事件

在本文中，我们将看到如何在Python的 PYGLET 模块中触发隐藏事件。 Pyglet 是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。 Windows 可能显示为浮动区域，也可以设置为填充整个屏幕（全屏）。当窗口被最小化或（在 Mac OS X 上）被用户隐藏时触发此事件。
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 hide 事件的语法，当这个事件被触发时这个方法被调用

@window.event       
def on_hide():
    print("Window is minimised")

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):
     
    print("nn")
    # key "C" get press
    if symbol == pyglet.window.key.C:
         
        # close the window
        window.close()
 
 
# on hide event
@window.event
def on_hide():
     
    # printing some message
    print("Window is minimized")
     
 
  
 
# image for icon
img = image = pyglet.resource.image("logo.png")
 
# setting image as icon
window.set_icon(img)
 
# minimize the window
window.minimize()
                
# start running the application
pyglet.app.run()

输出 ：

Window is minimized
