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

I found a stupid way, tried every attribute in palette, and it works for me when changing 'QPalette::Base'. Maybe you can have a try.

    pButton->setAutoFillBackground(true);
    QPalette palette = pButton->palette();
    //palette.setColor(QPalette::Window, QColor(Qt.blue));
    //palette.setColor(QPalette::Foreground, QColor(Qt.blue));
    palette.setColor(QPalette::Base, QColor(Qt.blue));
    //palette.setColor(QPalette::AlternateBase, QColor(Qt.blue));
    //palette.setColor(QPalette::ToolTipBase, QColor(Qt.blue));
    //palette.setColor(QPalette::ToolTipText, QColor(Qt.blue));
    //palette.setColor(QPalette::Text, QColor(Qt.blue));
    //palette.setColor(QPalette::Button, QColor(Qt.blue));
    //palette.setColor(QPalette::ButtonText, QColor(Qt.blue));
    //palette.setColor(QPalette::BrightText, QColor(Qt.blue));
    pButton->setPalette(palette);
    pButton->show();

I've struggled with same problem. You need to choose QPalette::Button instead of QPalette::Window. Qt reference says this: QPaletteButton - The general button background color. This background can be different from Window as some styles require a different background color for buttons. So I solved it this way:

        QPalette pal=this->palette(); \\"this" is my derived button class
        pal.setColor(QPalette::Window, style.background);
        QColor col=style.background; \\ my style wrapper, returns QColor
        this->setAutoFillBackground(true);
        this->setPalette(pal);

I had the same issue, but finally got this to work. I'm using Qt 5 with the Fusion color theme:

QPalette pal = button->palette();
pal.setColor(QPalette::Button, QColor(Qt::blue));
button->setAutoFillBackground(true);
button->setPalette(pal);
button->update();

Try these commands in the exact order as above, and if that still doesn't work, set your theme to Fusion and try again.

Good luck!

Changing the Dialog styleSheet Property works for me, set this property to:

QPushButton:pressed {
    background-color: qlineargradient(spread:pad, x1:0, y1:0, x2:0, y2:1,   stop:0 rgba(60, 186, 162, 255), stop:1 rgba(98, 211, 162, 255))
}
QPushButton {
     background-color: #3cbaa2; border: 1px solid black;
     border-radius: 5px;
}

QPushButton:disabled {
    background-color: rgb(170, 170, 127)
}

Answer 5

Add propoerty border:none; to the stylesheet

For some reason this removes the default background color also.

Example: background-color: rgba(46, 204, 113, 0.4); border: none;

Answer 6

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.
