调用的关键python

在主界面中，主函数首先建立次界面的类，而后在主界面类内部调用类让他显示。app

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()#

次界面调用UI_v21use.py3d

 

 

import sys
from PyQt5.QtWidgets import QApplication,QMainWindow,QFileDialog
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5 import QtWidgets, QtCore, QtGui
 


#导入本身建立的图形类
from UI.V21_teacherPublish import *
 
  

#一个是这个类自己的，一个是这个类继承
class UI21_MAIN(QMainWindow,Ui_MainWindow_V21):
 
    def __init__(self):
        #类的初始化
        super(UI21_MAIN, self).__init__()
        self.setupUi(self)#界面控件初始化              
              
        self.UI_Int()

    def open_v21(self):     
        print("打开窗口",1)    
    def open_v22(self):        
        print("打开窗口",2)    
   
         
    def UI_Int(self):
          
         #按钮绑定函数
        self.pushButton.clicked.connect(self.open_v21)  #开始按键
        self.pushButton_2.clicked.connect(self.open_v22)  #开始按键
       
    def closeEvent(self, event):
        
        print("QT关闭窗口")
        
'''            
 
if __name__ == '__main__':
 
  
    #----------------------QT界面主进程--------------------------------
    app = QApplication(sys.argv)
    
    ui=UI21_MAIN()
    ui.show()
    
    sys.exit(app.exec_())
 '''

　　

 

其余界面相似，测试时候能够只用一个界面测试code

 

 

额外说明orm

跨文件调用pyblog

1要在文件目录下建立一个空的__init__.py文件

2使用 文件名字.要调用的文件名字

 

 

 

界面转化命令
