How to catch mouse click in QDoubleSpinbox

[MasterBlade]

Hello I have a QDoubleSpinbox and I want to make it so that when a user clicks its value, it automatically selects the value so the user can type a new value to it.

I used the following event filter. But during my test, the function is only called when I click on the main framework (anywhere outside those spinboxes). What should I do?

bool MainWindow::eventFilter(QObject* obj, QEvent* event)
{
    if (event->type() == QEvent::MouseButtonPress){
        if (obj == ui->input){
            ui->input->selectAll();
            return true;
        }
        if (obj == ui->error){
            ui->error->selectAll();
            return true;
        }
    }
    return QObject::eventFilter(obj, event);
}

I don't know, but would it work if you sub-classed the QDoubleSpinbox and overrode its eventFilter() instead? You can have an eventFilter() on every QWidget (and then it is self-contained/standalone, does not rely on writing it in container), you don't have to have it on just your QMainWindow or whatever.

Hi,

You likely want to apply that to the QLineEdit used in the QDoubleSpinBox. See the lineEdit method to get it.
