min-height:25px;

border: 1px solid rgb(41, 57, 85);

border-radius: 3px;

background: white;

selection-background-color: blue;

min- 75px;

min-height: 35px;

}

QPushButton:enabled {

background: rgb(85, 85, 85);

}

QPushButton:enabled:pressed{

}

3、QMenu

sysMenu->setStyleSheet("QMenu {background-color:rgb(89,87,87); border: 3px solid rgb(235,110,36);}
QMenu::item{font - size: 10pt;color: rgb(225, 225, 225);border: 3px solid rgb(60, 60, 60);
background - color:rgb(89, 87, 87);padding:16px 16px;margin:2px 2px;}
QMenu::item:selected{background - color:rgb(235, 110, 36);}
QMenu::item:pressed{border: 1px solid rgb(60, 60, 61);background - color: rgb(220, 80, 6); }");

 4、蓝色风格QTableWidget

/*tabelwidget*/
QTableWidget{
text-align:center;
color:#E4D625;
background:#31419B;
border:1px solid #242424;
alternate-background-color:#B3C6E7;/*交错颜色*/
gridline-color:#242424;
}

/*选中item*/
QTableWidget::item:selected{
color:black;
background:#B3C6E7;
}

/*
悬浮item
QTableWidget::item:hover{
background:#FFFFFF;
}*/
/*表头*/
QHeaderView::section{
text-align:center;
background:#021482;
font:15pt;
padding:3px;
margin:0px;
color:white;
border:1px solid #242424;
border-left-0;
}

/*表右侧的滑条*/
QScrollBar:vertical{
background:#484848;
padding:0px;
border-radius:6px;
max-12px;
}

/*滑块*/
QScrollBar::handle:vertical{
background:#CCCCCC;
}
/*
滑块悬浮，按下*/
QScrollBar::handle:hover:vertical,QScrollBar::handle:pressed:vertical{
background:#A7A7A7;
}
/*
滑块已经划过的区域*/
QScrollBar::sub-page:vertical{
background:444444;
}

/*
滑块还没有划过的区域*/
QScrollBar::add-page:vertical{
background:5B5B5B;
}

/*页面下移的按钮*/
QScrollBar::add-line:vertical{
background:none;
}
/*页面上移的按钮*/
QScrollBar::sub-line:vertical{
background:none;
}

 设置代码可实现居中：

   int row = ui->tableWidget->rowCount();
    int columns = ui->tableWidget->columnCount();
    for (int i=0;i<row;i++)
    {
        for (int j=0;j<columns;j++)
        {
            ui->tableWidget->item(i,j)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);
        }
    }

 5、设置点击之后没有虚线

outline:0px
