发送消息和QTableWidget

发送消息和QTableWidget

发送消息

1.创建消息类

from PyQt5.Qt import QObject
from PyQt5.QtCore import pyqtSignal

class SignalCenter(QObject):
    	login_succeed_signal = pyqtSignal(str, int)
        
signal_center = SignalCenter()

2.发送消息

signal_center.login_succeed_signal.emit(username, result)

3.接受消息做出反应

signal_center.login_succeed_signal.connect(self.login_succeed)
def login_succeed(self, username, role):
	pass

QTableWidget

1.构造QTableWidget对象

self.left_view = QTableWidget(3, 1, self)

2.QTableWidgetItem对象

i1 = QTableWidgetItem('用户列表')

3.添加元素

self.left_view.setItem(0, 0, i1)

4.隐藏头部

self.left_view.verticalHeader().setVisible(False)
self.left_view.horizontalHeader().setVisible(False)
