step 1:使用qt designer建立.ui文件(helloworld.ui)python
step 2:建立一個獨立的main.py文件,並加載helloworld.uiapp
import sys from PyQt5 import QtWidgets from PyQt5.uic import loadUi class mywin(QtWidgets.QDialog): def __init__(self): super(mywin,self).__init__() loadUi('helloworld.ui',self) if __name__ == "__main__": app = QtWidgets.QApplication(sys.argv) w = mywin() w.show() w.setWindowTitle("window") sys.exit(app.exec_())
step3 運行main.pyui
