PYGLET–鼠标按钮串

原文:https://www.geeksforgeeks.org/pyglet-mouse-button-string/

在本文中，我们将看到如何在 python 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，用于开发视觉上丰富的图形用户界面应用程序，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，或者可以设置为充满整个屏幕(全屏)。鼠标状态处理程序类是一个简单的处理程序，从鼠标跟踪按钮的状态。如果一个按钮被按下，那么这个处理程序为它保存一个真值。鼠标字符串是描述一组活动鼠标按钮的字符串。
我们可以借助下面给出的命令
创建一个窗口

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


为了创建窗口，我们将 buttons_string 方法与 pyglet.window.mouse 一起使用
语法:mouse . buttons _ string(buttons)
参数:它以整数(即鼠标按钮常量的按位组合)作为参数
返回:它返回字符串

下面是实现

Python 3

# 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:
