PyQT调用ui界面文件

通过QtDesigner将ui文件转存为py文件

1. 不继承Ui_Form

import sys
from PySide6 import QtCore,QtWidgets
from PySide6.QtWidgets import *
from ui_test import Ui_Form

class readfile(QWidget):
    def __init__(self):
        super().__init__()  
        self.ui = Ui_Form()         
        self.ui.setupUi(self) 
        self.__create_connections()

    def __create_connections(self):              
        self.ui.pushButton.clicked.connect(self.open_file)        


    def open_file(self):        
        fname,_ = QFileDialog.getOpenFileName(self,"打开文件", '.')
        if fname:            
            self.ui.lineEdit.setText(fname)            
            with open(fname,'r') as f:
            	content = f.read()
            self.ui.textBrowser.setText(str(content))            
            


if __name__ == '__main__':
	app = QApplication(sys.argv)
	w = readfile()
	w.show()       
	sys.exit(app.exec())

2. 继承Ui_Form

import sys
from PySide6 import QtCore,QtWidgets
from PySide6.QtWidgets import *
from ui_test import Ui_Form

class readfile(Ui_Form,QWidget):
    def __init__(self):
        super().__init__()          
        self.setupUi(self) 
        self.__create_connections()

    def __create_connections(self):              
        self.pushButton.clicked.connect(self.open_file)        


    def open_file(self):        
        fname,_ = QFileDialog.getOpenFileName(self,"打开文件", '.')
        if fname:            
            self.lineEdit.setText(fname)            
            with open(fname,'r') as f:
            	content = f.read()
            self.textBrowser.setText(str(content))                 


if __name__ == '__main__':
	app = QApplication(sys.argv)
	w = readfile()
	w.show()       
	sys.exit(app.exec())
