可以使用以下代码实现:
```python
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QLineEdit
from PyQt5.QtGui import QGuiApplication
from PyQt5.QtCore import Qt, QProcess
class Example(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
self.setGeometry(300, 300, 300, 200)
self.setWindowTitle('Virtual Keyboard')
self.lineedit = QLineEdit(self)
self.lineedit.setGeometry(50, 50, 200, 30)
self.lineedit.setFocusPolicy(Qt.StrongFocus)
self.lineedit.editingFinished.connect(self.hideKeyboard)
self.show()
def hideKeyboard(self):
QGuiApplication.inputMethod().hide()
def focusInEvent(self, event):
if self.lineedit.hasFocus():
self.showKeyboard()
else:
self.hideKeyboard()
super().focusInEvent(event)
def showKeyboard(self):
osk_path = r'C:\Windows\System32\osk.exe'
process = QProcess(self)
process.start(osk_path)
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
```
当用户点击 `QLineEdit` 时,会弹出虚拟键盘 `osk.exe`。当用户点击其他部分时,虚拟键盘会隐藏。
