@Gojir4 said in Styling the QMdiArea using the the fusion style and QPalette (dark theme): darkPalette.setColor(QPalette::Disabled, QPalette::Shadow, QColor(r, g, b)); (Edited) tried, but it didn't work. I suspect that underneath it's a QLabel with a raised text but I don't know how to set the color of those using QPalette
