【Python-GUI】利用pyside2开发简单的GUI界面

from PySide2.QtCore import Signal,QObject


class MySignals(QObject):
    # 定义一种信号, 两个参数类型分别是OTextBrowser和字符串
    text_print = Signal(str)

        self.ui = QUiLoader().load('pyside2_login.ui')
        self.ui.loginButton.clicked.connect(self.login)

        self.ms.text_print.connect(self.printToGui)

    def printToGui(self, text):

                self.ms.text_print.emit(logmsg)
