Solved How to find button name?
-
I'm currently trying to find the button name with this but it says 'expression must have class type'.
QPushButton* button = (QPushButton*)sender(); QString btn = button.objectName();

Hi
When casting QWidgets please use the Qt version and not c-casts.void MainWindow::on_pushButton_2_clicked() { QPushButton *but = qobject_cast<QPushButton * >( sender() ); if (but) qDebug() << but ->objectName(); }
Note that if sender is not a QPushButtonm then "but" will be null and will crash
if you use it. Hence always use the if check :)
