PYGLET——鼠标按钮字符串

在本文中，我们将看到如何在Python中的 PYGLET 模块中使用鼠标按钮字符串。 Pyglet 是一个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）。鼠标状态处理程序类是一个简单的处理程序，用于跟踪来自鼠标的按钮状态。如果按下按钮，则此处理程序为其保存一个 True 值。鼠标字符串是描述一组活动鼠标按钮的字符串。
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)

In order to create window we use buttons_string method with pyglet.window.mouse
Syntax : mouse.buttons_string(buttons)
Argument : It takes integer i.e bitwise combination of mouse button constants as argument
Return : It returns string

编程需要懂一点英语

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)
     
 
       
# 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 mouse button string
value = pyglet.window.mouse.buttons_string(2 | 5)
 
# creating text from the value
text = "Mouse Button 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：
