Switching DesktopSettingsAware colors for a button

[cadol001]

If I have a button where it's default colors are set through the Desktop settings, can I switch out two of those colors?

For example:

    QPushButton* button = new QPushButton("hello world",this);
    QPalette pal = button->palette();
    pal.setColor(QPalette::Button, QPalette::Base);
    button->setAutoFillBackground(true);
    button->setPalette(pal);
    button->update();

In this code I'm setting the button color to QPalette::Base. This works as long as I restart the app whenever settings change, but I'd like to just specify to use the new QPalette::Base during runtime whenever the color changes. ie. switching from light theme to dark theme changes the default QPalette::Base color, but it only updates buttons that don't have their palettes changed.

How can I accomplish this?

Thanks

@cadol001 try this:

void MainWindow::changeEvent(QEvent *event)
{
    if (event->type() == QEvent::PaletteChange) {
       QPalette palette = QApplication::style()->standardPalette();
       palette.setColor(QPalette::Button, palette.color(QPalette::Base));
       button->setPalette(palette);
    }
 event->ignore();
}
