*QT 生成水晶圓角按鈕樣式*
不用任何圖示就可以生成水晶按鈕，看起來還是比較好看，直接上圖看效果

可以通過QPushButton 和QToolButton 實現
QPushButton具體程式碼如下：

QPushButton{  
       min-width:80px;  
       min-height:32px;  
    }  
 QPushButton{  
    color:rgb(233, 236, 243);  
    min-height:20;  
    border-style:solid;  
    border-top-left-radius
 
:2px;  
    border-top-right-radius:2px;  
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop:0 rgb(226,236,241),   
                                stop: 0.3 rgb(33,184,150),  
                                  stop: 1 rgb(29,170,140));  
    border:1px;  
    border-radius:5px;padding:2px 4px
 
;/*border-radius控制圓角大小*/  
    }  
    QPushButton:hover{  /*滑鼠放上後*/  
    color:rgb(233, 236, 243);  
    min-height:20;  
    border-style:solid;  
    border-top-left-radius:2px;  
    border-top-right-radius:2px;  
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop:0 rgb(226,236,241),   
                                stop: 0.3
 
 rgb(37,189,252),  
                                  stop: 1 rgb(32,170,240));  
    border:1px;  
    border-radius:5px;padding:2px 4px;  
    }  
    QPushButton:pressed{ /*按下按鈕後*/  
    color:rgb(233, 236, 243);  
    min-height:20;  
    border-style:solid;  
    border-top-left-radius:2px;  
    border-top-right-radius:2px;  
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop:0 rgb(226,236,241),   
                                stop: 0.3 rgb(38,190,255),  
                                  stop: 1 rgb(33,184,240));  
    border:1px;  
    border-radius:5px;padding:2px 4px;  
    };  

QToolButton 樣式如下：

QToolButton{  
       min-width:80px;  
       min-height:32px;  
    }  
    QToolButton{  
    color:rgb(233, 236, 243);  
    min-height:20;  
    border-style:solid;  
    border-top-left-radius:2px;  
    border-top-right-radius:2px;  
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop:0 rgb(226,236,241),   
                                stop: 0.3 rgb(33,184,150),  
                                  stop: 1 rgb(29,170,140));  
    border:1px;  
    border-radius:5px;padding:2px 4px;/*border-radius控制圓角大小*/  
    }  
    QToolButton:hover{  /*滑鼠放上後*/  
    color:rgb(233, 236, 243);  
    min-height:20;  
    border-style:solid;  
    border-top-left-radius:2px;  
    border-top-right-radius:2px;  
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop:0 rgb(226,236,241),   
                                stop: 0.3 rgb(37,189,252),  
                                  stop: 1 rgb(32,170,240));  
    border:1px;  
    border-radius:5px;padding:2px 4px;  
    }  
    QToolButton:pressed{ /*按下按鈕後*/  
    color:rgb(233, 236, 243);  
    min-height:20;  
    border-style:solid;  
    border-top-left-radius:2px;  
    border-top-right-radius:2px;  
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop:0 rgb(226,236,241),   
                                stop: 0.3 rgb(38,190,255),  
                                  stop: 1 rgb(33,184,240));  
    border:1px;  
    border-radius:5px;padding:2px 4px;  
    }  
    QToolButton:checked{    /*選中後*/  
    color:rgb(233, 236, 243);  
    min-height:20;  
    border-style:solid;  
    border-top-left-radius:2px;  
    border-top-right-radius:2px;  
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop:0 rgb(226,236,241),   
                                stop: 0.3 rgb(38,190,255),  
                                  stop: 1 rgb(33,184,240));  
    border:1px;  
    border-radius:5px;padding:2px 4px;  
    }
