Qt设置QLineEdit的背景色 [英] Qt Set Background Color of QLineEdit

问题描述

我正在尝试更改QLineEdit的背景颜色，我根本无法弄清.

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

我原本是这样尝试使用stylesheets

I tried using stylesheets originally like this

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

但是什么也没做.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);    

但是这也没有做任何事情.我整天都在找东西，什么也找不到.我是在做错什么，还是有另一种方法?

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); }");
