Ⅰ. Init

from PySide2.QtWidgets import * class Window:def __init__(self):self.win = QMainWindow() if __name__ == '__main__':app = QApplication([])w = Window()w.win.show()app.exec_()

from PySide2.QtWidgets import * if __name__ == '__main__':app = QApplication([])win = QMainWindow()win.show()app.exec_()

Ⅱ Example

from PySide2.QtWidgets import * class Window:def __init__(self):self.win = QMainWindow()self.win.resize(500, 400)self.win.move(700, 210)self.win.setWindowTitle("测试窗口") self.textEdit = QTextEdit(self.win)self.textEdit.move(50, 50)self.textEdit.resize(200, 300)self.textEdit.setPlaceholderText("请输入文本") self.button = QPushButton("button", self.win)self.button.move(300, 100)self.button.clicked.connect(self.btnClick) def btnClick(self):info = self.textEdit.toPlainText()# 获取文本信息print(info)# print("button被点击") if __name__ == '__main__':app = QApplication([])# win = QMainWindow()# win.show()w = Window()w.win.show()app.exec_()

1.自动生成代码

...from PySide2.QtCore import QFilefrom PySide2.QtUiTools import QUiLoader ... if __name__ == "__main__":app = QApplication([])win = QMainWindow()w = Ui_Form()w.setupUi(win)win.show()app.exec_()

2.动态加载ui文件

from PySide2.QtWidgets import *from PySide2.QtCore import QFilefrom PySide2.QtUiTools import QUiLoader class Window:def __init__(self):super(Window, self).__init__() # 从文件中加载UI定义qfile = QFile("demo1.ui")qfile.open(QFile.ReadOnly)qfile.close() # 从UI定义中动态创建一个相应的窗口对象, 将其内部文件定义为self.ui.buttonself.ui = QUiLoader().load(qfile) self.ui.button.clicked.connect(self.btnClick)# self.button.clicked.connect(self.btnClick) def btnClick(self):info = self.ui.textEdit.toPlainText()# 获取文本信息# info = self.textEdit.toPlainText()print(info) if __name__ == '__main__':app = QApplication([])w = Window()w.ui.show()# w.win.show()app.exec_()
