 使用方法：

 CToolButton *button=new CToolButton(this);button->setObjectName("MyButton");button->setGeometry(100,200,70,32);button->setPopupMode(QToolButton::InstantPopup);button->setMenu(menu1);

QToolButton#MyButton
{qproperty-icon: url(:/file_pressed.png) center;qproperty-normalIconPath: url(:/file_hover.png);qproperty-hoverIconPath: url(:/file_pressed.png);qproperty-iconSize: 18px 18px;qproperty-toolButtonStyle:ToolButtonTextBesideIcon;background-color:transparent;qproperty-text:"文件"; border:none;
}
QToolButton#MyButton:hover
{color:blue;
}
QToolButton#MyButton:pressed
{color:red;
}
QToolButton::menu-indicator{width:0px;}/*去掉右下方的三角*/
