Qt设置QLineEdit的背景颜色

2022-01-08 00:00:00 qt background qlineedit c++ palette

我正在尝试更改 QLineEdit 的背景颜色，但我根本想不通.

I'm trying to change the background color of the QLineEdit and I can't figure it out at all.

我尝试使用 stylesheets 原来是这样的

I tried using stylesheets originally like this

QLineEdit *le = new QLineEdit(); le->setStyleSheet("background:#000;");

但这并没有做任何事情.我尝试像这样使用 QPalette

but that didn't do anything. I tried using QPalette like this

QPalette palette; palette.setColor(QPalette::Base, Qt::black); palette.setColor(QPalette::Background, Qt::black); le.setPalette(palette);

但这也没有做任何事情.我一直在寻找一整天，找不到任何东西.我做错了什么还是有其他方法可以做到这一点?

but this didn't do anything either. I've been looking all day and can't find anything. am I doing something wrong or is there another way to do it?

推荐答案

对我来说很好:

QLineEdit *le = new QLineEdit(); le->setStyleSheet("QLineEdit { background: rgb(0, 255, 255); selection-background-color: rgb(233, 99, 0); }");
