pyqt5界面切换

调用的关键

在主界面中，主函数首先创建次界面的类，然后在主界面类内部调用类让他显示。

if __name__ == ‘__main__‘:
 
  
    #----------------------QT界面主进程--------------------------------
    app = QApplication(sys.argv)
    
    ui=UI1_MAIN()
    ui.show()
    
    ui21=UI21_MAIN()#必须在住函数定义，在类的内部定义不行
    #ui21.show()   
    ui22=UI22_MAIN()
    ui31=UI31_MAIN()
    ui32=UI32_MAIN()
    
    sys.exit(app.exec_())

触发按钮函数

    def open_v21(self):     
        print("打开窗口",1)
        #ui21=UI21_MAIN()#必须在主界面类外部，主函数定义
        ui21.show()#

其他界面类似，测试时候可以只用一个界面测试

额外说明

跨文件调用py

1要在文件目录下创建一个空的__init__.py文件

2使用文件名字.要调用的文件名字
