Hi I’ve been tracking QEvent::PaletteChange events, like this:
bool MainWindow::event(QEvent *event)
{
if (event->type() == QEvent::PaletteChange) {
QPalette p = palette();
m_clearColor = p.color(QPalette::Base);
emit clearColorChanged(m_clearColor);
}
return QMainWindow::event(event);
}
Event gets sent when switching between themes…
Of course, I’m just using the base colour as is, not trying to figure out if
it’s light or dark…
Hope this helps,
Mike
