在QLineEdit中以只读方式显示闪烁的光标,可以通过以下步骤实现:
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()
完整的代码示例:
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_()
这样,QLineEdit中的光标将以只读方式显示,并且会以一定的频率闪烁。
