Python PyQt5實戰(zhàn)項目之網(wǎng)速監(jiān)控器的實現(xiàn)
發(fā)布日期：2021-12-13 07:30 | 文章來源：源碼之家
簡介
看到了一個能夠輕松實現(xiàn)獲取系統(tǒng)運行的進程和系統(tǒng)利用率（包括CPU、內(nèi)存、磁盤、網(wǎng)絡(luò)等）信息的模塊–psutil模塊。這次利用psutil.net_io_counters()這個方法。
psutil模塊使用
>>> psutil.net_io_counters() # 獲取網(wǎng)絡(luò)讀寫字節(jié)／包的個數(shù)
snetio(bytes_sent=16775953, bytes_recv=712657945, packets_sent=216741, packets_recv=485775, errin=0, errout=0, dropin=0, dropout=0)
bytes_sent:上傳數(shù)據(jù)
bytes_recv: 接收數(shù)據(jù)

def mousePressEvent(self, event):
'''

'''
self.start_x = event.x()
self.start_y = event.y()
def mouseMoveEvent(self, event):
'''
重寫移動事件
'''
dis_x = event.x() - self.start_x
dis_y = event.y() - self.start_y
self.move(self.x()+dis_x, self.y()+dis_y)
- mousePressEvent()
獲取鼠標按下時的坐標位置(相對于窗口左上角)
- mouseMoveEvent()
當鼠標處于按下狀態(tài)并開始移動時，鼠標離窗口左上角的位置會不斷更新并保存在event.x()和event.y()中。
我們將更新后的x和y值不斷減去鼠標按下時的坐標位置，就可以知道鼠標移動的距離。最后再調(diào)用move方法將窗口當前坐標加上移動距離即可
