PYGLET - 无格式文档

在本文中，我们将了解如何在Python的 PYGLET 模块中创建无格式文档。 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）。无格式文档的布局通常是为了方便复制粘贴而无需添加结构，例如标题、缩进、字体变化。换句话说，我们可以说这个文档包含纯文本。

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 pyglet.text.document.UnformattedDocument( method
Syntax : pyglet.text.document.UnformattedDocument(text)
Argument : It takes string as argument
Return : It returns UnformattedDocument object

编程需要懂一点英语

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 Learn and Grow"
  
# batch object
batch = pyglet.graphics.Batch()
  
# creating a unformatted document
# unlike formatted document it is just plain text
document = pyglet.text.document.UnformattedDocument(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)
  
# creating a caret
caret = pyglet.text.caret.Caret(layout, color =(150, 255, 150))
  
  
  
# 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 == pyglet.window.key.C:
          
        # closing the window
        # window.close()
        pass
     
# image for icon
img = pyglet.resource.image("gfg.png")
 
# setting image as icon
window.set_icon(img)
 
  
# start running the application
pyglet.app.run()

输出：
