c – 带刻度文本标签的Qt滑块小部件

我会使用附带QLabel的QSlider,如下所示.我通常的免责声明是你可能需要自己进行一些微调和调整. @H_971_2@main.cpp中

#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,1,4);
            layout->addWidget(label1,1);
            layout->addWidget(label2,1);
            layout->addWidget(label3,2,1);
            layout->addWidget(label4,3,1);
            setLayout(layout);
        }
};

#include "main.moc"

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

@H_971_2@main.pro

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

构建并运行

qmake && make && ./main
