如何在QLineEdit中以只读方式显示闪烁的光标

lineEdit = QLineEdit()
lineEdit.setReadOnly(True)

timer = QTimer()
timer.setInterval(500)  # 设置定时器间隔为500毫秒

def toggleCursor():
    cursor = lineEdit.cursor()
    if cursor.hasSelection():
        cursor.clearSelection()
    else:
        cursor.select(QTextCursor.WordUnderCursor)
    lineEdit.setTextCursor(cursor)

timer.timeout.connect(toggleCursor)

timer.start()

from PyQt5.QtWidgets import QApplication, QLineEdit
from PyQt5.QtCore import QTimer, QTextCursor

app = QApplication([])

lineEdit = QLineEdit()
lineEdit.setReadOnly(True)

timer = QTimer()
timer.setInterval(500)

def toggleCursor():
    cursor = lineEdit.cursor()
    if cursor.hasSelection():
        cursor.clearSelection()
    else:
        cursor.select(QTextCursor.WordUnderCursor)
    lineEdit.setTextCursor(cursor)

timer.timeout.connect(toggleCursor)
timer.start()

lineEdit.show()
app.exec_()
