推荐答案

我将使用带有 QLabel 的 QSlider ，如下所示.我通常的免责声明是，您可能需要确定自己进行一些微调和调整.

I would use a QSlider with QLabel(s) attached as below. My usual disclaimer goes that you may need some fine-tuning and adjustment on your own for sure.

#include <QMainWindow>
#include <QApplication>
#include <QGridLayout>
#include <QSlider>
#include <QLabel>

class MainWindow Q_DECL_FINAL : public QMainWindow
{
    Q_OBJECT
    public:
        explicit MainWindow(QWidget *parent = Q_NULLPTR) : QMainWindow(parent)
        {
            QSlider *slider = new QSlider(Qt::Horizontal, this);
            slider->setRange(1, 4);
            slider->setSingleStep(1);
            QLabel *label1 = new QLabel("Novice", this);
            QLabel *label2 = new QLabel("Intermediate", this);
            QLabel *label3 = new QLabel("Advanced", this);
            QLabel *label4 = new QLabel("Expert", this);
            QGridLayout *layout = new QGridLayout;
            layout->addWidget(slider, 0, 0, 1, 4);
            layout->addWidget(label1, 1, 0, 1, 1);
            layout->addWidget(label2, 1, 1, 1, 1);
            layout->addWidget(label3, 1, 2, 1, 1);
            layout->addWidget(label4, 1, 3, 1, 1);
            setLayout(layout);
        }
};

#include "main.moc"

int main(int argc, char **argv)
{
    QApplication application(argc, argv);
    MainWindow mainWindow;
    mainWindow.show();
    return application.exec();
}

main.pro

TEMPLATE = app
TARGET = main
QT += widgets
SOURCES += main.cpp

构建并运行

qmake && make && ./main
