QT经验：[2]怎么设置QPushButton样式表

1、首先要定义一个QPushButton对象QPushButton button = new QPushButton（）；

2、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;}");

3、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);}"）；

4、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);}"）；
