一般对应fsndust文件的图象照应模块。具体的////系统右键菜单写注册表
//QString strValue = m_FileTransMainWnd->m_strAppPath+"/FYSystemRightButtonUploadU.exe %1";//系统右键菜单响应程序转发给主程序
//strValue.replace('/', '\\');
////文件
//m_FileTransMainWnd->RegSettings = new QSettings("HKEY_CLASSES_ROOT\\*\\shell\\RYFileTranClient", QSettings::NativeFormat);
//m_FileTransMainWnd->RegSettings->setValue(NULL,m_FileTransMainWnd->m_strRighttext);
//m_FileTransMainWnd->RegSettings = new QSettings("HKEY_CLASSES_ROOT\\*\\shell\\RYFileTranClient\\command", QSettings::NativeFormat);
//m_FileTransMainWnd->RegSettings->setValue(NULL,strValue);
////文件夹
//m_FileTransMainWnd->RegSettings = new QSettings("HKEY_CLASSES_ROOT\\Folder\\shell\\RYFileTranClient", QSettings::NativeFormat);
//m_FileTransMainWnd->RegSettings->setValue(NULL,m_FileTransMainWnd->m_strRighttext);
//m_FileTransMainWnd->RegSettings = new QSettings("HKEY_CLASSES_ROOT\\Folder\\shell\\RYFileTranClient\\command", QSettings::NativeFormat);
//m_FileTransMainWnd->RegSettings->setValue(NULL,strValue);
上面的这些在调试时会提示：ASSERT failure in QSettings:"empty key",file io\qsettings.cpp line322
将null换成"."后就可以了，而且可以写注册表
//系统右键菜单写注册表
QString strValue = m_FileTransMainWnd->m_strAppPath+"/FYSystemRightButtonUploadU.exe %1";//系统右键菜单响应程序转发给主程序
strValue.replace('/', '\\');
//文件
m_FileTransMainWnd->RegSettings = new QSettings("HKEY_CLASSES_ROOT\\*\\shell\\RYFileTranClient", QSettings::NativeFormat);
m_FileTransMainWnd->RegSettings->setValue(".",m_FileTransMainWnd->m_strRighttext);
m_FileTransMainWnd->RegSettings = new QSettings("HKEY_CLASSES_ROOT\\*\\shell\\RYFileTranClient\\command", QSettings::NativeFormat);
m_FileTransMainWnd->RegSettings->setValue(".",strValue);
//文件夹
m_FileTransMainWnd->RegSettings = new QSettings("HKEY_CLASSES_ROOT\\Folder\\shell\\RYFileTranClient", QSettings::NativeFormat);
m_FileTransMainWnd->RegSettings->setValue(".",m_FileTransMainWnd->m_strRighttext);
m_FileTransMainWnd->RegSettings = new QSettings("HKEY_CLASSES_ROOT\\Folder\\shell\\RYFileTranClient\\command", QSettings::NativeFormat);
m_FileTransMainWnd->RegSettings->setValue(".",strValue);
