I don't know. Maybe cache the value if isDarkMode() and see whether that changed after a signal emission. As for the workarea, calling d->color_cache_.clear(); should re-trigger the colors Toolbars looks more difficult, as there is no way to trigger a rebuild of the toolbars AFAICS. One way might be to save lightmode and darkmode icons, as we do for rtlIcon_ and switch that after the signal. Jürgen
