可以使用QLineEdit的setInputMethodHints()方法来设置输入法提示,例如设置Qt.ImhDigitsOnly表示只允许输入数字,这样在点击QLineEdit时就会自动弹出数字键盘。如果需要弹出osk虚拟键盘,可以使用QProcess类来启动osk.exe程序。具体实现可以参考以下代码:
```python
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QLineEdit
from PyQt5.QtCore import Qt, QProcess
class MyWidget(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.setInputMethodHints(Qt.ImhDigitsOnly) # 只允许输入数字
self.lineEdit.installEventFilter(self) # 安装事件过滤器
def eventFilter(self, obj, event):
if obj == self.lineEdit and event.type() == Qt.QEvent.MouseButtonPress:
# 点击QLineEdit时启动osk.exe程序
process = QProcess(self)
process.start('osk.exe')
return super().eventFilter(obj, event)
if __name__ == '__main__':
app = QApplication(sys.argv)
widget = MyWidget()
widget.show()
sys.exit(app.exec_())
```
