PYGLET——鼠标离开事件
在本文中,我们将看到如何在Python的 PYGLET 模块中触发鼠标离开事件。 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,或者可以设置为填充整个屏幕(全屏)。当鼠标移到窗口外时,将调用此事件。如果当前正在拖动鼠标,则不会触发此事件。请注意,鼠标指针的坐标将在窗口矩形之外。
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)
下面是鼠标离开事件的语法,当这个事件被触发时这个方法被调用
@window.event
def on_mouse_leave(x, y):
print("Mouse left the window")
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 centre
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):
# key "C" get press
if symbol == pyglet.window.key.C:
print("Key C is pressed")
# on mouse leave event
@window.event
def on_mouse_leave(x, y):
# printing some message
print("Mouse left the window")
# image for icon
img = image = pyglet.resource.image("logo.png")
# setting image as icon
window.set_icon(img)
# start running the application
pyglet.app.run()
输出 :
Mouse left the window
Mouse left the window
Mouse left the window
Mouse left the window
