首先要定义一个QPushButton对象
QPushButton button = new QPushButton（）；
设置button的字体类型、字体大小和字体颜色代码如下：
button->setStyleSheet"QPushButton{ font-family:'Microsoft YaHei';font-size:12px;color:#666666;}");
设置button的状态图片：正常、鼠标移入、鼠标点击状态的图片切换。代码如下：
button->setStyleSheet( "QPushButton{border-image: url(Resources/images/BreadCrumbNavigation/navigation_more_normal.png);}" "QPushButton:hover{border-image: url(Resources/images/BreadCrumbNavigation/navigation_more_hover.png);}" "QPushButton:pressed{border-image: url(Resources/images/BreadCrumbNavigation/navigation_more_pressed.png);}"）；

也可以同时设置这两种属性：
button->setStyleSheet( "QPushButton{font-family:'Microsoft YaHei';font-size:12px;color:#666666;}”
border-image: url(Resources/images/BreadCrumbNavigation/navigation_more_normal.png);}" "QPushButton:hover{border-image: url(Resources/images/BreadCrumbNavigation/navigation_more_hover.png);}" "QPushButton:pressed{border-image: url(Resources/images/BreadCrumbNavigation/navigation_more_pressed.png);}"）；

部件大小和字体设置
QPushButton quit("Quit");
quit.resize(75, 30);
quit.setFont(QFont("Times", 18, QFont::Bold));
