解决方法
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.
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();
}
main.pro
TEMPLATE = app TARGET = main QT += widgets SOURCES += main.cpp
构建并运行
qmake && make && ./main
