• PyQt: “AttributeError: 'Form' object has no attribute 'exec_'” when opening second window


    # -*- coding: utf-8 -*-
    
    import sys     
    from PyQt5.QtWidgets import QApplication , QMainWindow
    from PyQt5.QtCore import *
    from PyQt5.QtGui import *
    from PyQt5.QtWidgets import *
    from Ui_splashView import *
    from LoginMain import LoginMain
    
    class SplashMain(QMainWindow, Ui_Form):
        def __init__(self, parent=None):    
            super(SplashMain, self).__init__(parent)
            self.setWindowFlags(Qt.SplashScreen|Qt.FramelessWindowHint)
            self.setupUi(self)
            
            self.time=5
            self.timer=QTimer(self)
            self.timer.timeout.connect(self.countTime)
            self.timer.start(1000)
            
        def countTime(self):
            self.time-=1
            self.label_2.setText("还有"+str(self.time)+"秒跳转登入界面")
            if(self.time==0):
                self.close()
                self.myWin2 = LoginMain()  
                self.myWin2.show()  
                
                
                
    
                
    if __name__=="__main__":  
        app = QApplication(sys.argv)  
        myWin = SplashMain()  
        myWin.show()  
        sys.exit(app.exec_())  

    以上代码是 splash窗口负责欢迎提示的,然后关闭自身窗口打开一个新的窗口。

    以上红色部分的代码是修正以后的,之前的代码为:

                myWin2 = LoginMain()  
                myWin2.show()
    myWin2.exec_()

    如果这么写的话就会报错,如下:

    PyQt: “AttributeError: 'Form' object has no attribute 'exec_'” when opening second window

    照此修正,不再报错。
