可以通过以下代码实现： ```python from PyQt5.QtWidgets import QApplication, QMainWindow, QLineEdit, QPushButton from PyQt5.QtCore import Qt import os class MyWindow(QMainWindow): def __init__(self): super().__init__() self.initUI() def initUI(self): self.setGeometry(100, 100, 300, 200) self.setWindowTitle('Virtual Keyboard') self.lineEdit = QLineEdit(self) self.lineEdit.setGeometry(50, 50, 200, 30) self.lineEdit.mousePressEvent = self.showVirtualKeyboard self.button = QPushButton('Button', self) self.button.setGeometry(50, 100, 100, 30) self.button.clicked.connect(self.destroyLineEdit) def showVirtualKeyboard(self, event): os.system('osk.exe') def destroyLineEdit(self): self.lineEdit.deleteLater() if __name__ == '__main__': app = QApplication([]) window = MyWindow() window.show() app.exec_() ``` 当鼠标点击QLineEdit时，会弹出osk.exe虚拟键盘。当点击其他控件（如QPushButton）时，QLineEdit会被销毁。
