QSS优雅界面示例展示了通过Qt Style Sheets(QSS)实现的美观且用户友好的图形用户界面设计，为开发者提供了一系列界面美化技巧和实践案例。
比较漂亮的实例代码如下：
```cpp
#include iconhelper.h
IconHelper* IconHelper::_instance = 0;
IconHelper::IconHelper(QObject* parent)
: QObject(parent)
{
int fontId = QFontDatabase::addApplicationFont(:/image/fontawesome-webfont.ttf);
QString fontName = QFontDatabase::applicationFontFamilies(fontId).at(0);
iconFont = QFont(fontName);
}
void IconHelper::SetIcon(QLabel* lab, QChar c, int size)
{
iconFont.setPointSize(size);
lab->setFont(iconFont);
lab->setText(c);
}
void IconHelper::SetIcon(QPushButton* btn, QChar c, int size)
{
iconFont.setPointSize(size);
btn->setFont(iconFont);
btn->setText(c);
}
```
