我直接用QMotifStyle 类设置风格：QApplication::setStyle(new QMotifStyle );
但链接时出现如下错误：
Preferences.obj : error LNK2001: unresolved external symbol "public: virtual void __thiscall QMotifStyle::drawControl(enum QStyle::ControlElement,class QPainter *,class QWidget const *,class QRect const &,class QColorGroup const &,unsigned int,class QStyleOption const &)const " (?drawControl@QMotifStyle@@UBEXW4ControlElement@QStyle@@PAVQPainter@@PBVQWidget@@ABVQRect@@ABVQColorGroup@@IABVQStyleOption@@@Z)

........
我的静态库qmotifsytle.lib加入到工程里了。环境：vc6+qt3.3.5。
请问这是怎么回事？？？？？
