Qt里内置了一批图标，qstyle.h头文件里有QStyle::StandardPixmap枚举了这些图标，接下来一起看看这些图标分别是什么样，如何使用内置图标。

Qt版本:Qt5.9.6，操作系统:windows10。

### 1.  先看看这些图标的枚举值及官方描述。 ###

### 2.  接下来揭开这些图标的庐山真面目 ###

QGridLayout *layout = new QGridLayout(this);
 int iconIndex = 0;
 
 for (int row = 0; row < 7; ++row)
 {
 for (int col = 0; col < 10; ++col)
 {
 enum QStyle::StandardPixmap standardIcon = (enum QStyle::StandardPixmap)iconIndex;
 layout->addWidget(new QPushButton(QApplication::style()->standardIcon(standardIcon),
 QString::number(iconIndex++)), row, col);
 }
 }
 layout->addWidget(new QPushButton( QApplication::style()->standardIcon(QStyle::SP_LineEditClearButton),
 QString::number(QStyle::SP_LineEditClearButton)), 7, 0);
 
 this->setLayout(layout);

### 3.  最后附上一句使用Qt logo的示例代码 ###

this->setWindowIcon( QIcon(QApplication::style()->standardIcon(QStyle::SP_TitleBarMenuButton)) );
