Qt Development QLineEdit Cursor Color

[byrAlpha]

I'm trying to customize the QLineEdit cursor (the blinking caret), especially its color and thickness. I’ve tried both QPalette::Text and QLineEdit { color: xxx; } in stylesheet, but the cursor remains black regardless of these settings.

I’ve confirmed that QTextEdit allows customizing cursor color via palette, but QLineEdit does not respond to that. Even using a dark background, the insertion cursor remains hard to see.

I also checked Qt source code and found the cursor is drawn in QWidgetLineControl::draw(), using p.setPen(pal.text().color()). However, stylesheet seems to override palette partially.

Is there an official or recommended way to override QLineEdit’s caret color? Or is subclassing + reimplementing paintEvent() the only way?
