Qt 用样式实现实心圆和空心圆

实心圆和空心圆的样式

//实心圆
background-color: qradialgradient(spread:pad, cx:0.5, cy:0.5, radius:0.5, fx:0.5, fy:0.5, stop:0 rgba(63, 158, 208, 255), stop:0.8 rgba(63, 158, 208, 255),stop:0.85 rgba(255, 255, 255, 255) );

//空心圆
background-color: qradialgradient(spread:pad, cx:0.5, cy:0.5, radius:0.5, fx:0.5, fy:0.5, 
stop:0 rgba(255, 255, 255, 255), 
stop:0.7 rgba(255, 255, 255, 255), 
stop:0.8 rgba(63, 158, 208, 255),
stop:0.85 rgba(255, 255, 255, 255) 
);

例子：

QLabel *label = new QLabel(this);
    if(label)
    {
        if(solid == SOLID)//实心圆
        {
            label->setStyleSheet("background-color: qradialgradient(spread:pad, cx:0.5, cy:0.5, radius:0.5, fx:0.5, fy:0.5, stop:0 rgba(63, 158, 208, 255), stop:0.8 rgba(63, 158, 208, 255),stop:0.85 rgba(255, 255, 255, 255) );");
        }
        else if(solid == HOLLOW)//空心圆
        {
            label->setStyleSheet("background-color: qradialgradient(spread:pad, cx:0.5, cy:0.5, radius:0.5, fx:0.5, fy:0.5,stop:0 rgba(255, 255, 255, 255), stop:0.7 rgba(255, 255, 255, 255), stop:0.8 rgba(63, 158, 208, 255),stop:0.85 rgba(255, 255, 255, 255) );");
        }
        else//空白
        {
            label->setStyleSheet("background-color: rgba(255, 255, 255, 255);");
        }
    }
