QT小技巧

滑条的美化

美化前

代码如下

    //滑条的美化
    ui->horizontalSlider->setStyleSheet(
                "QSlider::groove:horizontal {"
                "border:1px solid skyblue;"
                "background-color:skyblue;"
                "height:10px;"
                "border-radius:5px;"
                "}"

                "QSlider::handle:horizontal {"
                "background:qaradialgradient(spread:pad,cx:0.5,cy:0.5,radius:0.5,fx:0.5,fy:0.5,stop:0.7 white,stop:0.8 rgb(140,212,255));"
                "width:20px;"
                "border-radius:10px;"
                "margin-top:5px;"
                "margin-bottom:-5px;}"

                "#horizontalSlider::sub-page:horizontal{"
                "background:red;"
                "margin:10px;"
                "border-radius:5px;}"
                );

窗口的设计

    //禁止使窗口放大
    setWindowFlags(windowFlags()&~Qt::WindowMaximizeButtonHint);
    //设置窗口大小
    setFixedSize(width(),height());
