PYGLET – 键修饰符字符串

在本文中,我们将看到如何在Python的 PYGLET 模块中获取修饰符的键字符串值。 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。 Windows 可能显示为浮动区域,也可以设置为填充整个屏幕(全屏)。键状态处理程序类是一个简单的处理程序,用于跟踪键盘上的键状态。如果按下某个键,则此处理程序为其保存一个 True 值。修饰符字符串返回描述一组修饰符的字符串。

我们可以在下面给出的命令的帮助下创建一个窗口

# creating a window
window = pyglet.window.Window(width, height, title) 

下面是实现

Python3
# importing pyglet module
import pyglet
import pyglet.window.key as 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 = "Welcome to GeeksforGeeks Have a nice day"
   
# batch object
batch = pyglet.graphics.Batch()
   
# creating document
document = pyglet.text.document.FormattedDocument(text)
   
# setting style to the document
document.set_style(0, len(document.text), dict(
                         font_name ='Arial', font_size = 16, 
                         color =(255, 255, 255, 255)))
   
# creating a incremental text layout
layout = pyglet.text.layout.IncrementalTextLayout(
               document, 400, 350, batch = batch)
 
# making layout to display multiline
layout.multiline = True
   
# creating a caret
caret = pyglet.text.caret.Caret(layout, color =(255, 255, 255))
   
# caret to window push handlers
window.push_handlers(caret)
   
# setting caret style
caret.set_style(dict(font_name ="Arial"))
   
   
# on draw event
@window.event
def on_draw():
       
    # clear the window
    window.clear()
       
    # draw the batch
    batch.draw()
       
    # caret to window push handlers
    window.push_handlers(caret)
     
     
 
# creating a key state handler
key_handler = pyglet.window.key.KeyStateHandler()
       
# key press event    
@window.event
def on_key_press(symbol, modifier):
   
    # key "C" get press
    if symbol == key.C:
         
        # printing the message
        print("Key : C is pressed")
         
# image for icon
img = image = pyglet.resource.image("gfg.png")
 
# getting modifier string
value = key.modifiers_string(10 | 20)
 
# creating text from the value
text = "Modifier to string : " + str(value)
 
# setting this text to the document
document.text = text
   
# setting image as icon
window.set_icon(img)
    
# start running the application
pyglet.app.run()


输出 :
