Qt5 - setting background color to QPushButton and QCheckBox

Question

I\'m trying to change the background color of a QAbstractButton (either a QPushButton or QCheckBox) in Qt5 and having zero luck.

This does nothing:

p         


        

Answer 1

Try this:

QColor col = QColor(Qt::blue);
if(col.isValid()) {
   QString qss = QString("background-color: %1").arg(col.name());
   button->setStyleSheet(qss);
}

as mentioned at the QT Forum by @goetz.

I used some different definition of Qcolor col as QColor col = QColor::fromRgb(144,238,144); and this works for me.
