首先是定义宏定义：头文件中

//以下是图标的宏设定

#ifndef TREE_ITEM_ICON_Project

#define TREE_ITEM_ICON_Project QStringLiteral("treeItem_Project")

#endif

#ifndef TREE_ITEM_ICON_folder

#define TREE_ITEM_ICON_folder QStringLiteral("treeItem_folder")

#endif

#ifndef TREE_ITEM_ICON_folderOriginal

#define TREE_ITEM_ICON_folderOriginal QStringLiteral("treeItem_folder-ansys")

#endif

#ifndef TREE_ITEM_ICON_folderAnsys

#define TREE_ITEM_ICON_folderAnsys QStringLiteral("treeItem_folder-ansys")

#endif

#ifndef TREE_ITEM_ICON_TdmsGroup

#define TREE_ITEM_ICON_TdmsGroup QStringLiteral("treeItem_group")

#endif

#ifndef TREE_ITEM_ICON_TdmsChannel

#define TREE_ITEM_ICON_TdmsChannel QStringLiteral("treeItem_channel")

#endif

#ifndef TREE_ITEM_ICON_DataItem

#define TREE_ITEM_ICON_DataItem QStringLiteral("treeItem_dataItem")

#endif

在类的成员中添加：

private:
    QMap<QString,QIcon> m_publicIconMap;///< 存放公共图标

接着在构造函数中：添加图标

    m_publicIconMap[TREE_ITEM_ICON_Project] = QIcon(QStringLiteral(":/treeIcon/res_treeItemIcon/Project.png"));

    m_publicIconMap[TREE_ITEM_ICON_folder] = QIcon(QStringLiteral(":/treeIcon/res_treeItemIcon/folder.png"));

    m_publicIconMap[TREE_ITEM_ICON_folderAnsys] = QIcon(QStringLiteral(":/treeIcon/res_treeItemIcon/folder-ansys.png"));

    m_publicIconMap[TREE_ITEM_ICON_TdmsGroup] = QIcon(QStringLiteral(":/treeIcon/res_treeItemIcon/group.png"));

    m_publicIconMap[TREE_ITEM_ICON_TdmsChannel] = QIcon(QStringLiteral(":/treeIcon/res_treeItemIcon/channel.png"));

    m_publicIconMap[TREE_ITEM_ICON_folderOriginal] = QIcon(QStringLiteral(":/treeIcon/res_treeItemIcon/folder_original.png"));

    m_publicIconMap[TREE_ITEM_ICON_DataItem] = QIcon(QStringLiteral(":/treeIcon/res_treeItemIcon/dataItem.png"));

接着就可以使用图标了：

QStandardItem* itemProject = new QStandardItem(m_publicIconMap[QStringLiteral("treeItem_Project")],QStringLiteral("项目1"));
