How to set QPlainTextEdit text background color?

[Violet Giraffe]

I've tried setStyleSheet with "background-color: #rrggbb", it does the trick, but it also affects scrollbars. How to set just the text bg color?

Hi!

QPalette p = ui->plainTextEdit->palette();
p.setColor(QPalette::Active, QPalette::Base, Qt::black);
ui->plainTextEdit->setPalette(p);
ui->plainTextEdit->setBackgroundVisible(false);

If you want to change only the color of the entire viewport background (except scrollbar), must specify a selector.

like this:

ui->plainTextEdit->setStyleSheet("QPlainTextEdit {background-color: #rrggbb;}")

And if you want to set only the text background color,

like this:

QTextCharFormat fmt;
fmt.setBackground(QBrush(Qt::yellow));
ui->plainTextEdit->mergeCurrentCharFormat(fmt);
