So, I added a QTStackedWidget named: stackedWidget (as default). The problem is in mainwindow.cpp, I added a custom SLOT that contain: ui->stackedWidget->setCurrentIndex(1); when I build this the compiler says: mainwindow.cpp:25: error: no member named 'stackedWidget' in 'Ui::MainWindow' ui->stackedWidget-

Is there a standard mime-type I can use for this - providing file paths as mime data? 回答1: QMimeData has a functionality to add a text/uri-list . To drag/drop a file onto the system add a QUrl that starts with
