一、简述

QSS：全称 Qt Style Sheets（Qt样式表），用于美化Qt程序界面，类似于CSS，但不如CSS强大，选择器和属性较少。Qt定制化CSS。

QSS可以通过控件对象的setStyleSheet方法设置控件样式。

二、控件样式设置

2.1边框线

2.1.1按钮QPushButton

  1 //线粗细：1px
  2 //线类型：solid实线
  3 border:1px solid;

2.2背景色/字体颜色

2.2.1表格表行头/列头颜色

行头颜色(行列交叉也设置背景颜色)：

  1 QHeaderView::section::horizontal,QTableCornerButton:section{ padding:3px; margin:0px; color:#DCDCDC;  border:1px solid #242424; border-left-width:0px; border-right-width:1px; border-top-width:0px; border-bottom-width:1px; background:qlineargradient(spread:pad,x1:0,y1:0,x2:0,y2:1,stop:0 #646464,stop:1 #525252); } QTableWidget{background-color:white;border:none;}
  2 QTableWidget::item:hover{background-color:rgb(92,188,227,200)}
  3 QTableWidget::item:selected{background-color:#1B89A1}

列头颜色：

  1 QHeaderView::section::vertical,QTableCornerButton:section{ padding:3px; margin:0px; color:#DCDCDC;  border:1px solid #242424; border-left-width:0px; border-right-width:1px; border-top-width:0px; border-bottom-width:1px; background:qlineargradient(spread:pad,x1:0,y1:0,x2:0,y2:1,stop:0 #646464,stop:1 #525252); } QTableWidget{background-color:white;border:none;}
  2 QTableWidget::item:hover{background-color:rgb(92,188,227,200)}
  3 QTableWidget::item:selected{background-color:#1B89A1}

2.3控件圆角弧度

  1 //角弧度，半径5的圆
  2 
  3 border-radius:5px;

2.4鼠标悬停颜色
